In dry-mix cementitious tile adhesive plants running horizontal twin-shaft forced-action mixers of 600–2,000 kg nominal capacity, ELOTEX FX7000 is metered at 2.5–4.0 wt% on total dry mortar using loss-in-weight feeders. The powder is a vinyl acetate–ethylene redispersible polymer with a minimum film-forming temperature of approximately 0 °C by DIN ISO 2115, an ash content typically 9–13 wt%, and an oversize fraction on a 400 μm sieve below 4%. The powder is supplied under REACH Regulation (EC) No 1907/2006 and does not require a CLP (EC) No 1272/2008 hazard label. It disperses in alkaline cement paste without pre-emulsification; after hydration and drying, the ethylene-rich film bridges microcracks at the tile-to-substrate interface. Compliance in this segment is established under EN 12004-1:2017 and EN 1348:2007, with C2, C2S1, C2S2, C2TE, and C2E product types evaluated for tensile adhesion, open time, and slip resistance. The production sequence places the powder after cement but before fine fillers; dropping the powder directly onto high-velocity mixing shafts has been observed to increase baghouse filter clogging and batch air content. End product types include large-format porcelain tile adhesives, deformable adhesives for underfloor heating screeds, and low-VOC C2TE adhesives. The low film formation temperature contributes to adhesion retention after heat-ageing cycles, but published counter-test data against all three EN 1348:2007 conditioning regimes for this specific grade remains limited. Storage requires unopened bags below 30 °C and relative humidity below 60%; moisture uptake above 0.5% induces lump formation in pneumatic conveying lines and should be avoided.
At the formulation stage, flexible cementitious waterproofing slurries containing ELOTEX FX7000 at 3.5–7.0 wt% dry-mortar basis are processed in 500–1,000 kg high-shear dissolvers before water addition. The harmonised compliance framework is EN 14891:2017; relevant assessed properties include water impermeability, crack bridging, and adhesion after normal, water-immersion, and heat-ageing conditions. The dry blend is pre-mixed with CEM I 52.5R, 0.1–0.5 mm quartz sand, cellulose ether, and calcium formate for 180 s at 12–16 m/s tip speed before discharge into paper bags with polyethylene liners or directly into site silos. At the point of use, wet slurry is mixed at 400–800 rpm with a water-to-powder ratio between 0.18–0.22, then applied by airless spray at 6–10 bar or by notched trowel in two passes to achieve 1.5–2.0 mm cured thickness. End product types include balcony membranes under tile beds, basement tanking slurries, wet-room sub-tile membranes, and cementitious pool surrounds. A field-observed bottleneck occurs when slurry is stored beyond 30 min; viscosity above 120,000 mPa·s at 20 °C causes spray atomization failure. Without sufficient defoamer, air entrainment above 4 vol% has reduced membrane adhesion to concrete by roughly 20–30%, evidenced by blistering under 48-hour ponding tests. The ethylene-rich film retains elongation after alkaline exposure, but formulators must verify crack bridging at the actual curing temperature because hydration below 5 °C delays film coalescence.
When a calcium sulfoaluminate–Portland cement blend is selected for self-leveling floor underlayments, addition of 1.5–3.5 wt% ELOTEX FX7000 on dry mix moderates surface curl and reduces edge lifting after water evaporation. EN 13813:2002 governs screed material performance, while placement over heated slabs follows EN 1264-4 for hydronic underfloor heating systems. In 2,000 kg twin-shaft mixers, the powder is homogenized with fast-setting cements, fine limestone fillers, and polycarboxylate ether superplasticizer for 240–300 s; continuous planetary mixers at the site operate with water-to-powder ratios of 0.19–0.23. Flow is determined by a 30-mm Hagerman ring with a target spread of 150–180 mm at 5 min. False set has been observed when calcium sulfoaluminate content exceeds 25 wt% and mixer discharge temperature exceeds 35 °C, producing pump pressure spikes above 20 bar in piston rotor pumps. End product types include high-build floor underlayments for vinyl and ceramic floor coverings, renovation screeds over old concrete, and cementitious overlays over heated hydronic systems. The polymer film contributes to low curl, but dosage above 4.0 wt% can delay setting and reduce 28-day compressive strength by 10–15% when tested under EN 13892-3 relative to the unmodified reference.
ETICS base coat production at 1,500 kg batch scale requires a redispersible polymer with low film formation temperature to maintain impact resistance and glass-fibre mesh adhesion without increasing VOC content. ELOTEX FX7000 is added at 2.0–4.0 wt% of dry mortar and blended with cement, 0.2–0.7 mm graded limestone or quartz aggregates, hydrophobic admixtures, and air-entraining control agents. The European technical assessment route for external thermal insulation composite systems is EAD 040083-00-0404, with bond strength to insulation measured according to EN 13494 and impact resistance under ETAG 004-derived methods; water vapour permeability is assessed by EN ISO 7783-1. Downstream processing uses low-shear twin-shaft mixers followed by fluid-bed cooling to below 28 °C before bagging; on-site mixing at 400–600 rpm produces a workable mortar with water-to-powder ratio of 0.16–0.20. Trowel application embeds 160 g/m² alkali-resistant glass-fibre mesh in a 3–6 mm base coat. End products include base coats for EPS and mineral-wool external insulation boards, renovation base coats over old concrete, and reinforced mesh-bedding mortars. In coastal high-humidity installations, hydrophobic admixture levels above 0.5 wt% are often needed to avoid polymer film leaching from early rain exposure.
Because EN 1504-3 R4 repair mortars must retain compressive strength above 45 MPa while remaining sprayable, ELOTEX FX7000 is introduced at 3.0–6.0 wt% of dry mix in products formulated for structural and non-structural concrete repair. The compliance path includes EN 206:2013 for concrete, EN 1504-3:2005 for repair products, and ASTM C928-19 for export-oriented packaged repair materials. Production on 1,000 kg twin-shaft dry-mix lines incorporates silica fume, quartz sands, and shrinkage-compensating agents before polymer addition; dry-spray equipment then applies the material with water-to-powder ratio between 0.13–0.17 at air pressure of 4–6 bar. Sprayed layers range from 10–50 mm per pass, with rebound controlled below 10% when the polymer film and microsilica grading are balanced. End product types include bridge pier spalling repair mortars, parking deck patching compounds, and chloride-contaminated concrete overlay repair systems. At polymer addition above 6.0 wt%, some production trials have recorded compressive strength below the EN 1504-3 R4 limit of 45 MPa at 28 d; this is the operational boundary for structural overlays. Field data indicate that low-Tg VAE powder improves adhesion to damp substrates but does not by itself compensate for inadequate cement content or insufficient cover depth against carbonation.
For cementitious tile grouts produced in 500 kg ribbon mixers, ELOTEX FX7000 is metered at 1.0–2.5 wt% of dry mix to improve pigment dispersion and reduce water absorption after cure under ISO 13007-3:2014 CG2 and EN 13888:2009 classification paths. Dry raw materials are mixed for 150–180 s before iron oxide pigments are added; water demand is typically 0.18–0.22 by weight of powder. The wet grout is applied with a rubber trowel into joints between 1–8 mm, then washed after a setting time of 20–40 min. End products include ready-mix fine grouts for porcelain floor tiles, polymer-modified wall grouts for wet-room installations, and industrial floor grouts. At addition levels above 2.5 wt%, some formulations show a decline in 28-day compressive strength of 8–12% relative to unmodified grout; therefore upper dosage is verified per batch. The powder is not intended for movement joints; joints designed for dynamic movement require silicone or polyurethane sealants rather than cementitious grout.

ELOTEX FX7000 is a redispersible polymer powder based on a vinyl acetate–ethylene (VAE) copolymer. It is manufactured by emulsion polymerization followed by spray drying with a mineral anti-caking agent to maintain free flow and prevent cold-blocking during storage. The product is intended for dry-mix mortars in the construction sector, particularly cementitious tile adhesives, flexible waterproofing slurries, patching compounds, and repair mortars. The grade is distinguished by a glass transition temperature of approximately −14 °C and a minimum film formation temperature of 0 °C, values that allow polymer film coalescence at low application temperatures and separate it from conventional higher-Tg VAE powders. FX7000 is not a standalone adhesive; it is a polymer modifier that redisperses in water during mortar mixing to form a latex-like dispersion. Final tensile adhesion, deformability, water resistance, and open time are governed by the complete formulation, including cement type, aggregate grading, water demand, and curing conditions.
During cement hydration, redispersed polymer particles deposit on cement gel surfaces and within capillary pores. As free water is consumed, the particles pack and coalesce into a continuous polymer film that bridges microcracks, increases cohesive strength, and contributes viscoelastic deformation. In mortars containing FX7000, this film-forming mechanism occurs at substrate temperatures down to 5 °C because the minimum film formation temperature is 0 °C. A VAE powder with a higher minimum film formation temperature may remain particulate and fail to develop coherent film strength under the same conditions. The polar vinyl acetate units promote adhesion to siliceous aggregates and ceramic tile backs, while the ethylene comonomer reduces chain rigidity and lowers the glass transition temperature. The film does not chemically crosslink in cement; it develops through thermoplastic interdiffusion of polymer chains, so high-temperature exposure above 60 °C softens the film and reduces shear modulus.

When dispersed at 50 wt% in demineralized water, FX7000 forms a milky, stable dispersion. The published viscosity range of 1,500–4,000 mPa·s at 25 °C is specific to this concentration and should not be used to predict the rheology of a finished cementitious mortar. Mortar viscosity is dominated by the water-to-powder ratio, aggregate fines, cellulose ether, and admixture package. The powder redisperses rapidly under low-shear mixing when dry-blended into the aggregate and cement; direct addition to water may create lumps. In automated dry-mix plants, gravimetric feeding is preferred because bulk density variations of ±100 g/L can alter the polymer dosage if volumetric screw feeders are used.
The ash value of 10–14 % reflects the inorganic anti-caking component. This mineral fraction does not participate as a binder and must be included in dry-mix formulation mass balances. In high-accuracy laboratory mortars, the powder should be preconditioned in a closed container at 23 °C and 50 % relative humidity before weighing. The redispersed particle size distribution is governed by the original emulsion and is typically submicronic; the dry powder sieve residue on 400 µm mainly identifies coarse anti-caking clusters or locally caked material.
Formulation requirements for cementitious tile adhesives are specified in EN 12004-2:2017. FX7000 is typically incorporated at 3.0–4.5 wt% based on dry mortar mass in flexible and deformable tile adhesive formulations. At these addition levels, the low-Tg VAE polymer reduces the elastic modulus of the hydrated cement matrix and supports transverse deformation values needed for S1 and S2 definitions under EN 12002:2008. The classification is assigned to the finished mortar, not to the polymer powder. A C2 adhesive must achieve tensile adhesion strengths of ≥1.0 MPa under dry, water-immersion, heat-ageing, and freeze-thaw cycles; C1 adhesives require ≥0.5 MPa. The contribution of FX7000 is formulation-dependent because cement grade, aggregate surface area, water/cement ratio, and curing history control the final microporosity and polymer film distribution.
In production, FX7000 should be dry-blended with cement, graded silica sand, cellulose ether, and auxiliary additives in a twin-shaft batch mixer or high-efficiency forced-action mixer. A workable sequence is to premix the fine components for 2–3 min, add cement and FX7000, and continue mixing for 3–5 min to achieve homogeneity. High-shear heat build-up above 60 °C should be avoided because the powder may soften and agglomerate if the anti-caking mineral is not distributed evenly. For continuous automated lines, loss-in-weight feeders provide better accuracy than screw feeders. Hopper bridging is possible due to the low bulk density and defined particle surface; fluidization pads or mechanical agitators should be used when hopper outlet diameters are below 200 mm.
On site, the dry mortar is mixed with water, typically for 2–3 min, allowed to slake, and remixed. Final workability and open time are strongly influenced by cellulose ether and water-retention agents; FX7000 does not by itself extend open time. Air content should be checked by EN 1015-7:1998, especially in machine-applied thin-bed mortars. If air content exceeds approximately 3–4 %, defoamer dosage or mixing intensity should be adjusted. The low minimum film formation temperature is advantageous on low-absorbent substrates, such as existing ceramic tile or metal, where thin-bed water loss is rapid. Film formation can still occur when the substrate temperature is 5–10 °C, which is a critical boundary for exterior work in cold climates.
Compared with general-purpose VAE redispersible powders whose glass transition temperatures are at or above 0 °C, FX7000 shifts failure behavior from brittle to ductile and is better suited to movement scenarios caused by thermal cycling, substrate shrinkage, or timber-frame vibration. The trade-off is lower shear strength at elevated service temperatures. Under sustained temperatures above 60 °C, a lower-Tg film softens more readily than a higher-Tg VAE or acrylic powder; therefore, FX7000 is not preferred for high-shear industrial flooring at elevated operating temperatures. Compared with acrylic redispersible powders, FX7000 generally shows good compatibility with alkaline cementitious matrices but lower inherent ultraviolet resistance. It should be specified for pigmented cementitious systems and tile adhesives, not for clear or exterior film applications requiring UV-stable polymer films. Published direct comparative data between FX7000 and named alternative grades is limited; benchmarking should be performed in the same mortar formulation using identical water demand and curing conditions.
Compared with liquid polymer dispersions, FX7000 reduces transported water mass and eliminates freeze-thaw damage in liquid storage. The powder is added to the dry mix and redisperses on site; this simplifies logistics for dry-mix manufacturers. However, dry mixing equipment and moisture protection are required, and direct site addition to water is not recommended. Liquid latex may be more appropriate where a producer lacks dry-mix equipment or where an additional polymer component is required for a simple cement-sand mortar.
In cementitious flexible waterproofing slurries, FX7000 is used at 20–30 wt% of total dry mix where crack-bridging and low-temperature adhesion are specified. Crack-bridging ability should be tested according to EN 14891:2017, including after exposure to 4 °C. The powder contributes to low-temperature flexibility and adhesion on concrete and masonry substrates. These formulations contain a high polymer volume fraction and require careful control of air voids and mix rheology. A two-layer application with a reinforcing fabric is common for movement joints, sumps, and balcony surfaces. Published data for this specific configuration is limited, so trial mixes and site application tests are required before approval.
FX7000 is supplied in moisture-resistant multi-layer paper bags with a polyethylene liner. Storage should be below 30 °C and below 60 % relative humidity. Unopened bags typically retain performance for 12 months from the production date when stored correctly. The powder is hygroscopic and will cake if exposed to moisture; opened bags should be resealed and used within 6 months. In bulk silo storage, conveying air should be dried or dew-point-controlled to prevent condensation in lines. As an organic powder, FX7000 can form combustible dust concentrations; local ATEX directives require dust explosion assessments and good housekeeping during bag emptying and silo filling.
Known incompatibilities are primarily with non-aqueous systems. The powder should not be added to solvent-borne adhesives, solvent-containing admixtures, or strong oxidizers. In cementitious systems, high-dose calcium chloride accelerators may increase ionic strength and destabilize the redispersed polymer; chloride-free accelerators are preferred where embedded steel must be protected from corrosion. Polycarboxylate ether superplasticizers and lignosulfonates can alter the adsorption environment and should be tested with the specific cement and aggregate combination. Calcium aluminate cement and rapid-setting systems may require compatibility trials because the polymer can affect setting kinetics and water demand.

For commercial building specifications, product acceptability is normally assessed through the complete mortar under project-specific conditions. Classification values quoted in third-party certifications refer to the formulated product, not to the polymer powder alone. The grade’s contribution is best isolated by comparing mortar performance with and without FX7000 at constant workability.
In gypsum-based patching compounds, addition levels of 2.0–5.0 wt% can improve sanding cohesion and reduce edge cracking. The powder should be dry-blended with gypsum, retarder, and filler before adding water. Because gypsum hydration is less alkaline and often slower than cement hydration, the polymer film forms later, and low minimum film formation temperature remains important in thin trowel applications at 10–15 °C. FX7000 is not a substitute for retarder or water-retention cellulose. Published data for this specific configuration is limited, and gypsum-specific trial batches are required to confirm setting time, adhesion, and surface hardness.
