ELOTEX HD2040 is supplied as a vinyl acetate-ethylene redispersible polymer powder with a hydrophobic modifying package. In a dry-mix route to an EN 12004:2012+A1:2021 C2TE classification, the powder is incorporated at 2.5–3.5 wt% of total dry weight into a blend of CEM I 42.5 R, graded quartz sand 0.06–0.5 mm, cellulose ether with a Brookfield viscosity of 15,000–40,000 mPa·s, and 0.5–1.0 wt% calcium formate accelerator. Dry blending in a twin-shaft paddle mixer of 100–500 kg batch capacity is held to 180–240 s at a tip speed below 3.0 m/s; material temperature is maintained below 35°C because the polyvinyl alcohol protective colloid softens at elevated temperatures and causes powder agglomeration. Wet mixing on site requires 23–25 parts water per 100 parts dry mortar in a planetary paddle mixer at 140–285 rpm for 60–90 s, followed by a 5 min slaking period and 15 s remix. Under EN 1348/ISO 13007-2, tensile adhesion after 7-day water immersion and after heat ageing at 70°C must remain above 1.0 MPa. On dense porcelain tiles, field failures are typically cohesive within the polymer-cement matrix or interfacial at the tile back when the open time exceeds the skinning limit. Terminal products include large-format exterior porcelain tile adhesives for swimming pools and ventilated façades.
Replacing a conventional VAE powder with HD2040 in an EPS-based external thermal insulation composite system changes capillary water uptake and reduces the water supply that drives render cracking at mesh interfaces. Formulations designed to EAD 040083-00-0404 and EN 998-1 use 3.0–5.0 wt% HD2040 with CEM II/A-M 42.5, limestone sand 0–1.0 mm, an air-entraining agent, cellulose ether, and 0.2–0.5 wt% calcium stearate. Dry blending in a helical ribbon blender at a fill ratio of 50–70% and a mixing time of 6–10 min prevents fines segregation; high-shear pin mixers are not recommended because the hydrophobic shell on the powder particle can be mechanically stripped. The wet base coat is applied at 4–6 mm thickness over EPS boards, and alkali-resistant glass fibre mesh is embedded at the mid-thickness by trowel pressure. Capillary water absorption under EN 1062-3 on a cured base coat typically falls below 0.5 kg/m²·h⁰·⁵; values above 0.7 kg/m²·h⁰·⁵ correlate with field reports of premature render cracking after freeze-thaw cycling. Premature exposure to freeze-thaw before 28 days curing must be avoided because the latex film has not reached full modulus development. Terminal products include thin-render systems over EPS and mineral wool boards.
When the specification for a cementitious waterproofing slurry is written against EN 14891, HD2040 is incorporated at 3.5–5.0 wt% of the powder component. The formulation combines CEM I 42.5 N, quartz sand 0.1–0.5 mm, a 6 mm polyester fibre at 0.3–0.5 wt%, and a powdered defoamer. Mixing at 300–450 rpm with a high-torque paddle for 90 s, followed by a 3 min slaking period and 30 s remix, disperses the powder without damaging the polymer particles; high-speed dispersers above 800 rpm introduce air and lower the water impermeability performance under the 1.5 bar for 7 days test of EN 14891. The slurry is applied in two coats of 1.0–1.5 mm wet film thickness each, with the second coat placed after the first has set but before the surface has dried. Crack-bridging testing under EN 14891 at 23°C requires a minimum crack width of 0.75 mm; formulations near 4.0 wt% HD2040 and 0.4 wt% fibre approach this value, while published data for thinner coats is limited. Film coalescence is interrupted at substrate temperatures below 5°C; cold joints and surface whitening at the coat interface are indicators of incomplete polymer film formation. At ambient relative humidity above 60%, fine sand must be pre-dried to below 0.05% moisture before dry blending to prevent silo bridging. Terminal products include balconies, wet rooms, and internal basement tanking.
Flowable cementitious underlayments for floor coverings mix ELOTEX HD2040 at 2.0–4.0 wt% into a ternary binder system of ordinary Portland cement, calcium aluminate cement, and anhydrite. The dry blend also contains silica sand 0.1–0.3 mm, a polycarboxylate superplasticizer at 0.3–0.8 wt%, a powdered defoamer, and a lithium carbonate accelerator. Water demand is adjusted to 20–24 parts per 100 parts dry mix to achieve a flow ring spread of 220–260 mm under EN 12706. Mixing is performed in a continuous mixing pump or a low-speed paddle mixer at 500–700 rpm for 2 min; prolonged mixing beyond 10 min causes air entrainment and surface pinholes after pouring. Hardened screed is classified to EN 13813 with compressive class C30 and flexural class F6. The polymer content reduces edge curl and increases adhesion to concrete substrates, but incomplete dry blending of the polymer into the calcium aluminate cement phase can retard early setting. Field data from pumped installations show that residual moisture in sand above 0.1% increases the incidence of micro-cratering on the surface. Terminals include underlayment below luxury vinyl tile and large-format ceramic tile.

| Structural repair mortar | EN 1504-3 class R4 | 2.0–4.5 wt% | Wet-spray screw pump | ≥45 MPa compressive strength, ≥2.0 MPa bond |
| Cementitious tile grout | EN 13888 CG2 WA | 1.5–3.5 wt% | Forced action mixer 50–200 L | ≤5 g at 30 min, ≤10 g at 240 min |
| Exterior mineral render | EN 998-1, EN 1062-3 | 2.0–4.0 wt% | Ploughshare mixer 90–120 rpm | ≤0.3 kg/(m²·min⁰·⁵) capillary water absorption |
A sulphate-resistant repair mortar classified to EN 1504-3 class R4 uses HD2040 at 2.0–4.5 wt% to meet the ≥45 MPa compressive strength requirement, the ≤0.05% chloride ion content limit, and the ≥2.0 MPa direct tensile bond requirement on concrete substrates. The dry mix comprises CEM I 52.5 R, densified silica fume at 5.0–8.0 wt%, quartz sand 0.2–0.5 mm, a shrinkage-compensating agent, and a polycarboxylate superplasticizer. Substrate preparation by high-pressure water jetting at 15–25 MPa removes laitance and creates a surface roughness profile of 1.5–2.5 mm. The repair mortar is applied by trowel or wet-spray equipment with a screw pump; wet density is controlled to 2,050–2,150 kg/m³. The polymer film forms after cement hydration and lowers capillary water absorption, but polymer addition above 5.5 wt% can reduce compressive strength below class R4 through increased air entrainment. Under EN 1542, pull-off adhesion values for field samples must exceed 2.0 MPa; cohesive failure in the concrete substrate is the preferred mode. Pre-bagged material must be stored below 30°C and below 60% relative humidity to prevent partial redispersion in the valve bag. Terminal products include overhead and vertical structural patch repairs on bridge decks and marine concrete.
Hydrophobic modification of tile grout against efflorescence transport is achieved by adding HD2040 at 1.5–3.5 wt% to a cementitious grout matrix of CEM I 42.5 N, calcium carbonate filler 0–0.2 mm, pigment, and water-repellent admixtures. The product is mixed to a stiff paste with 18–20 parts water per 100 parts dry grout and applied diagonally across joints with a hard rubber float; joints are compacted and then smoothed with a damp sponge after initial set. Per EN 13888 CG2 WA, water absorption after 30 min and 240 min must remain below 5 g and 10 g, respectively, using the method of EN 12808-5, and abrasion resistance under EN 12808-2 must not exceed 2,000 mm³. The hydrophobic polymer film reduces chloride ingress in swimming pool joints and discourages calcium hydroxide migration that causes efflorescence on coloured grouts. However, the film is not a substitute for low-cement design; if the cement content exceeds 35 wt% of the dry mix, free lime transport can still create surface discolouration. On production-scale forced action mixers of 50–200 L, the powder is added after pigments to avoid colour streaking; material temperature must stay below 32°C. Terminals include exterior facade mosaics and immersed tiling systems.
Mineral render for fair-faced concrete and masonry substrates incorporates HD2040 at 2.0–4.0 wt% to reduce surface cracking and water staining. The formulation uses CEM II/B-M 32.5 R, limestone sand 0.1–0.8 mm, hydrated lime at 5.0–10.0 wt%, and a methyl cellulose ether. Dry mixing in a horizontal ploughshare mixer at 90–120 rpm for 5 min produces a homogeneous powder that is then applied by stainless steel trowel or spray machine with a screw pump at 15–18 bar air pressure. The polymer-modified render must achieve a capillary water absorption coefficient below 0.3 kg/(m²·min⁰·⁵) under EN 1062-3 after 28 days of curing; this threshold reduces freeze-thaw damage on unprotected substrates. Because VAE films are thermoplastic, surface temperatures above 60°C on dark-coloured render can lower film modulus and increase soiling pick-up. Overworking the surface with a sponge before initial set disrupts film formation at the surface and produces laitance layers with lower adhesion under EN 1542. Terminal products include exterior render coats on low-rise masonry buildings.

ELOTEX HD2040 is a redispersible polymer powder based on a vinyl acetate-ethylene copolymer that is spray-dried with a protective colloid system and supplied as a free-flowing white powder. The product is intended for dry-mix mortar modification, particularly in cementitious tile adhesives, self-leveling underlayments, repair mortars, and waterproofing slurries. It is dry-blended with hydraulic binders and aggregates before water addition, and it redisperses into primary polymer particles during mixing. Product specifications are normally reported through bulk density, residue on a 315 µm or 400 µm screen, ash content, and the pH of the redispersed dispersion. Exact values are lot-specific and appear on the certificate of analysis; published data for this specific configuration is limited. The powder is hygroscopic and should be stored below 40 °C in closed bags, because exposure to high relative humidity produces caking and increases the risk of silo bridging during pneumatic transfer.
In bulk handling, the free-flowing powder is transferred by vacuum or screw conveyor into weigh hoppers. The powder is sensitive to static charge at low relative humidity; dust extraction systems should be designed to avoid fine particle loss. Field observations from dry-mix plants indicate that batch-to-batch variation in bulk density can affect gravimetric dosing accuracy unless the hopper software uses density-compensated setpoints. The powder should not be combined with liquid plasticizers or solvents in the dry mix, as this causes agglomeration in the mixer. If older bags are used, screening through a 1 mm sieve before blending removes soft lumps.
The polymer particles consist of a vinyl acetate-ethylene backbone in which ethylene segments reduce the glass transition temperature of the dried film and provide flexibility without external plasticizer addition. During spray drying, the aqueous dispersion is converted into a free-flowing powder embedded in a water-soluble protective colloid matrix, usually polyvinyl alcohol. The particle size distribution is designed to balance dry-mix segregation resistance and rapid redispersion; typical redispersible VAE powders of this type exhibit a bulk density in the range of 400 kg/m³ to 600 kg/m³ and a residual moisture content below 2 wt%, but the HD2040 certificate of analysis is the controlling document. Under mixer shear, the powder agglomerates break down into primary polymer particles below 5 µm, which then coalesce around cement grains and silica sand surfaces as free water is consumed by hydration. The final polymer phase is not a continuous film across the entire mortar cross-section; it is a network of film bridges located in the interfacial transition zone and pore throats. The minimum film-forming temperature is sufficiently low for application at 10 °C and above, although capillary pressure and cement hydration assist coalescence at lower surface temperatures.
The interaction between the redispersed polymer and the cement pore solution determines early film formation. Calcium ions and hydroxyl ions in the pore water interact with the protective colloid and can reduce its solubility beyond the first minutes after mixing. The powder is generally compatible with ordinary Portland cement and calcium aluminate cement systems, but compatibility with high-sulfate formulations should be checked because polyvinyl alcohol-based colloids can be destabilized by strongly acidic accelerators. In high-pH environments, partial hydrolysis of vinyl acetate units occurs at the film surface; this reaction is slower for ethylene-modified copolymers and contributes to the improved wet resistance of HD2040. Because film formation depends on water removal and hydration, the cure schedule has a measurable effect: wet adhesion after 7 days standard cure and 21 days water immersion is not equivalent to adhesion after 28 days dry storage. A formulation that shows cohesive failure at 2.5 wt% HD2040 under dry conditions may still show adhesive failure after immersion if the polymer film has not fully coalesced.
The addition of HD2040 changes the rheological profile of a fresh cementitious tile adhesive from shear-thinning to a more pronounced thixotropic response. Low-shear viscosity increases as the polymer particles adsorb onto cement grains and fill fine pores; this increases water retention and trowelability. Open time is evaluated by applying a thin adhesive layer, waiting 10 min to 30 min, and then placing tiles before testing adhesion according to EN 1346. The polymer film that forms on the surface is a diffusion-limiting layer; if it forms too early, it can reduce wetting of the tile backface and cause a drop in adhesion. This is why film-forming polymer powders are balanced with cellulose ethers that extend open time. The combined effect of HD2040 and cellulose ether is not additive; adsorption competition between the protective colloid and the cellulose ether can produce a viscosity plateau that is sensitive to mixing speed and temperature.
HD2040 is differentiated from unmodified VAE powders by a hydrophobic modification on the polymer backbone or at the film surface. This change reduces the equilibrium water uptake of a coalesced film and limits plasticization during prolonged water exposure. The practical consequence appears in tensile adhesion testing according to EN 1348, where specimens are cured for 7 days under standard conditions and then immersed in water for 21 days before pull-off. Unmodified VAE films tend to show a larger decrease in adhesion after immersion because absorbed water reduces film cohesion and weakens the interfacial bond. The hydrophobic character of HD2040 reduces this loss but does not eliminate it; the cement matrix remains porous, and water transport through capillary pores occurs independently of film hydrophobicity. Free-film water absorption can be tested in accordance with ISO 62, but film casting conditions, thickness, and drying history affect the result. Consequently, wet strength retention should be evaluated in the target mortar formulation rather than from polymer film data alone.
| Performance parameter | Standard designation | Role in specification |
|---|---|---|
| Dry tensile adhesion | EN 1348, EN 12004 | Evaluates bond strength after 28-day cure and film coalescence |
| Water immersion adhesion | EN 1348, EN 12004 | Quantifies wet strength retention and hydrophobic effect |
| Open time | EN 1346 | Determines skinning and trowelability after extended working time |
| Slip resistance | EN 1308 | Measures movement on vertical substrates for wall tile adhesives |
| Classification | ISO 13007-1 | Defines C1/C2 and optional adhesive characteristics |
In production-scale dry-mix manufacture, HD2040 is added to the mixer after a portion of the silica sand and cement has been charged to avoid polymer particle adhesion to hot mixer walls. Twin-shaft paddle mixers and ploughshare mixers with batch capacities between 500 kg and 2000 kg are commonly used. Dry blending times of 10 min to 15 min are typical, but heat generation from extended shear can soften the polymer particles and form agglomerates that do not redisperse. Laboratory evaluation is performed in an EN 196-1 planetary mortar mixer; a representative procedure uses low-speed mixing at 140 rpm for 30 s, then high-speed mixing at 285 rpm for 60 s. Water demand is adjusted with a polycarboxylate ether superplasticizer to reach a flow of 150–170 mm. Air content of the fresh mortar is measured by the pressure method in EN 1015-7; air contents above 5% are common with polymer-modified mixes and may require an antifoam agent. The material is then applied to a concrete substrate with a notched trowel and covered with porcelain tiles; pull-off adhesion is measured after the specified storage conditions.

Styrene-acrylic redispersible powders typically offer higher tensile strength and better heat resistance than standard VAE powders, but they usually require a higher minimum film-forming temperature and may produce stiffer films. HD2040 belongs to the higher-ethylene VAE class, which provides lower film-forming temperature and greater elongation at low addition levels. The replacement is not a one-to-one weight substitution. Protective colloid content, alkali resistance, and water demand differ between polymer types, and these differences shift dosage response. A reformulation should compare tensile adhesion after water immersion, tensile adhesion after freeze-thaw cycling, and transverse deformation according to EN 12004; the transverse deformation test distinguishes deformable adhesives classified as S1 or S2. In exterior applications exposed to repeated freezing, the hydrophobic film of HD2040 may retain a higher fraction of the dry adhesion than an unmodified VAE, but direct comparative data against a specific styrene-acrylic grade is limited in public sources. The formulator must also check air void stability and mortar skinning, since styrene-acrylic powders can differ from VAE powders in their interaction with cellulosic thickeners.
Within the ELOTEX range, HD2040 is generally specified where hydrophobicity and flexibility are required simultaneously, whereas standard VAE grades are selected for general-purpose adhesives with lower wet strength demands. The hydrophobic modification changes the film surface energy and can alter adhesion to low-energy tile backfaces; contact angle testing is not a routine mortar test but may be used for polymer film characterization. Compared with a high-ethylene VAE grade without hydrophobic modification, HD2040 typically shows lower water absorption of a free film but similar elongation. The difference is more visible after immersion than after dry cure. Formulators using standard VAE grades can sometimes approach HD2040 wet adhesion by increasing dosage, but this also increases air entrainment and may reduce compressive strength. Therefore, the selection of HD2040 is justified when water immersion adhesion is the limiting specification and when standard VAE powders at higher dose create processing problems.
Thermal aging resistance is evaluated by conditioning specimens at 70 °C for 14 days before pull-off testing in some high-performance adhesive specifications. VAE films can undergo progressive hydrolysis and embrittlement under sustained heat, while the ethylene content of HD2040 reduces the number of hydrolyzable acetate groups per unit mass. The result is less loss of elongation after heat aging compared with unmodified VAE, although product-specific comparative data is limited. This property is relevant for tile adhesives installed over underfloor heating or in warm climates.
Self-leveling underlayments and repair mortars use HD2040 to improve adhesion to calcium sulfate substrates and to reduce surface dusting. In these systems, the powder is combined with high-alumina cement, calcium sulfate hemihydrate, lithium carbonate, and graded fillers. Flow is controlled by the water-to-solids ratio, typically 0.22–0.28, and by a polycarboxylate ether superplasticizer; the addition of the polymer powder increases plastic viscosity and may require a slightly higher dosage of dispersant. Flow spread is measured by a ring test according to EN 12706, with target spreads often between 220 mm and 260 mm after 5 min. Surface dusting is a common failure mode when the polymer film does not coalesce at the surface before drying; this is more frequent at low ambient temperature or low relative humidity. Pre-conditioning the dry mix to 18–25 °C before water addition and avoiding rapid air movement across the installed surface reduce this defect. HD2040 does not replace the plasticizer or the leveling binder; it contributes to adhesion, flexibility, and surface quality.
In cementitious waterproofing slurries applied at wet film thicknesses up to 2 mm, HD2040 is added at 3.0–7.0 wt% of dry solids. The mixed slurry is applied by brush or airless spray; airless spray equipment requires a wear-resistant rotor-stator pump and operating pressures above 0.8 MPa to prevent clogging. The polymer-modified slurry develops crack-bridging capacity only if the film is allowed to coalesce after application and before curing water evaporates. Pinhole defects can form when a dried skin develops too early, which is a processing boundary for sprayed membranes. The powder improves adhesion to damp concrete but does not remove the need for substrate preparation to saturated surface-dry condition in accordance with the membrane system’s specification. Its incompatibility boundary includes strongly acidic accelerators and high levels of aluminum sulfate, which destabilize the protective colloid and reduce redispersibility. HD2040 is therefore specified as a dry-mix modifier within a formulated hydraulic binder system, not as a standalone binder or liquid polymer replacement.
