In resilient floor covering adhesive production for luxury vinyl tile, vinyl composition tile, and fiberglass-backed sheet goods, the critical performance variable is retention of peel adhesion after plasticizer diffusion from the tile into the adhesive film. VINNAPAS 5710 N is a polyvinyl alcohol-stabilized vinyl acetate-ethylene copolymer dispersion with delivery pH of 4.0–5.0, nominal solids of 55 ± 1 wt%, anionic character, and an MFFT near 0°C. In wet-set adhesive formulations, it is added at 32–44 wt% as supplied, with the remaining wet phase comprising 35–50 wt% calcium carbonate filler, 5–12 wt% tackifier dispersion, 0.3–0.8 wt% wetting agent, 0.1–0.3 wt% biocide, and 0.2–0.7 wt% associative rheology modifier. Compounding is performed in a low-sweep planetary mixer or vacuum disperser with a butterfly rotor at 20–35 rpm; vacuum below −0.08 MPa is applied for 15–20 min to degas the compound. Batch temperature must remain below 35°C: above this threshold, polyvinyl alcohol-stabilized dispersions can shear-thin irreversibly and form micro-grit that rejects trowel ribs. Batch-to-batch variation in filler moisture above 0.3 wt% shifts open time by up to 5 min; therefore, calcium carbonate is pre-dried or moisture-monitored before charging. The applied adhesive is tested according to EN 14259 for floor covering adhesive requirements, ASTM D6862-11 for 90° peel resistance, GB 18583-2008 for interior hazardous substance limits, and REACH regulation (EC) No 1907/2006 for registration and authorization obligations. The lower addition limit is 30 wt%; below this level, plasticizer uptake from LVT produces a soft film at the adhesive interface and edge ooze. Above 44 wt%, viscosity in vacuum mixing exceeds 80,000 mPa·s and air release is insufficient. The terminal finished products are professional wet-set adhesives packaged in 14–20 kg pails for LVT, LVP, VCT, and fiberglass-backed vinyl sheet installation.
Tufted broadloom and carpet tile manufacture places the precoat compound as the load-bearing layer between primary backing and secondary backing. VINNAPAS 5710 N is used in this layer because it does not embrittle after oven cure and maintains adhesion to both polypropylene and nonwoven polyester. A standard precoat formulation mixes 100 dry parts calcium carbonate with 80–120 parts VINNAPAS 5710 N, 0.4–1.0 part polyacrylate thickener, 0.1–0.3 part fatty alcohol defoamer, and optional 0.5–2.0 parts dispersing agent. The compound is adjusted to 5,000–8,000 mPa·s at 20 rpm on a Brookfield RVT viscometer and applied by lick roll or doctor blade at 800–1,200 g/m² wet add-on. The secondary backing is introduced at a nip pressure of 2–5 bar, and the composite is dried in a three-zone flatbed oven at 110–135°C to a residual moisture content below 1.0 wt%. Delamination strength is measured according to ISO 11857; specification floorplans commonly set ≥ 1.5 N/50 mm as the lower control line for broadloom, while carpet tile constructions may require higher precoat wet-out because of surface tension differences in the secondary backing. Finished carpet is classified under EN 1307, and low-emission programs such as CRI Green Label Plus are typically applied to the final floor covering. Boric acid and borax must not be used as flame retardant synergists in this formulation; borate ions complex with the polyvinyl alcohol stabilizer and produce a false-body viscosity increase that collapses under shear. Flame retardant requirements are met with aluminum trihydrate, pre-dispersed with 0.2–0.5 part wetting agent before addition. The terminal products include tufted broadloom, carpet tiles, and automotive floor mats.
When an airlaid nonwoven line switches from a self-crosslinking acrylic to an APEO-free vinyl acetate-ethylene binder, the drying profile must be rebalanced because polyvinyl alcohol-stabilized VAE forms a surface film earlier than acrylic dispersions. VINNAPAS 5710 N is applied at 12–25 wt% binder solids on dry fiber mass for high-loft wipes and acquisition layers. The dispersion is diluted with deionized water to 8–15% solids before spray or foam deposition through a multi-nozzle manifold. Through-air drum drying uses a first zone at 120–130°C and a final zone at 140–150°C with dwell times of 8–25 s; if the first zone exceeds 150°C or dryer humidity rises above 65% RH, a skin forms on the web surface and internal water is trapped, producing lower caliper recovery and non-uniform tensile strength. The binder must be filtered through 100 µm in-line strainers because cationic fiber treatments can coagulate the anionic dispersion at the nozzle; nozzle tip fouling is the dominant production bottleneck when such chemicals are present. Industry compliance pathways for hygiene and food-adjacent grades include FDA 21 CFR 176.170 and 176.180 for paper and paperboard in food contact, OEKO-TEX Standard 100 product class I for baby wipes, ISO 9073-3 for strip tensile, ISO 9073-2 for caliper, and ISO 9073-6 for absorption capacity. The resulting terminal products are airlaid tabletop, wet wipes, industrial wipes, and acquisition distribution layers for hygiene cores.
For large-format porcelain and low-absorption stone, a two-component cementitious adhesive transfers deformability into the cured mortar through a liquid polymer phase. VINNAPAS 5710 N is used in the liquid component at 30–50 wt% as supplied, with the balance deionized water, 0.2–0.5 wt% defoamer, 0.1–0.3 wt% preservative, and sufficient wetting agent to wet cement at the mix ratio. The powder component is a blend of 35–40 wt% ordinary Portland cement, graded silica sand, and 0.3–0.6 wt% cellulose ether. The powder-to-liquid ratio is 3:1 to 4:1 by weight; lower liquid ratios reduce deformability and increase water demand. Mixing is carried out with a forced-action paddle at 300 rpm for 120 s, followed by 5 min slake and 30 s remix. Pot life closes at 60–90 min at 23°C; below 5°C, cement hydration and polymer film formation are both retarded. Air entrainment is controlled below 3.5%; excessive air reduces tensile adhesion after heat aging. The cured adhesive is classified under EN 12004:2017 and ISO 13007-1. Published product-specific data for dispersion-class D1/D2 tile adhesives based on this exact grade is limited; the C2 pathway should be confirmed with a laboratory batch before lot validation. The terminal finished products are two-component tile adhesive systems packaged as 25 kg powder plus 5–6 kg liquid canister for large-format porcelain and low-absorption stone installation.

Paper-to-paperboard lamination for folding cartons and tube winding balances water resistance and adhesive strike-through control through solids content and rheology. A starting lamination adhesive based on VINNAPAS 5710 N uses 65–80 wt% dispersion as supplied, 5–15 wt% of a 10% polyvinyl alcohol solution, 0.2–0.5 wt% deaerator, and water to a final viscosity of 1,500–2,500 mPa·s. The adhesive is applied by engraved roller or rubber roll at 10–25 g/m² dry coat weight, then wet-laminated under nip pressure of 3–6 bar. Stack curing at 20–25°C for 24–48 h develops full bond strength. Above 25 g/m² dry coat weight, blocking under stack pressure above 0.05 MPa increases unless the stack surface is kept below 35°C. Food-contact compliance is supported by FDA 21 CFR 176.170 and 176.180, EU 1935/2004, and BfR Recommendation XXXVI/1 for paper and board. The terminal products are folding cartons, book covers, paper tube winding, and litho-laminated corrugated display board.
Flat lamination of high-pressure laminate, resin-impregnated decorative paper, and edge banding to MDF or particleboard uses a water-based adhesive blend in which VINNAPAS 5710 N reduces cold-press time and increases low-temperature flexibility. The wet adhesive contains 20–40 wt% VINNAPAS 5710 N, 25–45 wt% PVAc dispersion, 5–15 wt% calcium carbonate filler, and water to a viscosity of 8,000–15,000 mPa·s. The blend is applied by roll coater at 60–120 g/m² wet; cold pressing at 0.5–1.0 MPa for 30–60 min fixes the laminate, followed by hot pressing at 70–90°C for 2–5 min where water resistance is required. Non-structural durability is tested according to EN 204 and EN 205, with D2 and D3 classification depending on exposure sequence; ANSI/HPVA HP-1 may apply to decorative laminate bonds in North American markets. The adhesive must not be adjusted with trivalent metal salts such as aluminum chloride, because coagulation occurs below pH 4.0; substrate moisture should be conditioned to 8–12% to prevent steam blisters at the hot-press interface. The terminal products are laminated MDF panels for cabinet doors, wardrobe backs, desk tops, and interior partition cladding.

VINNAPAS 5710 N is a redispersible polymer powder based on a polyvinyl alcohol-stabilized vinyl acetate-ethylene copolymer. The product is produced by spray drying of an aqueous dispersion and supplied as a white to off-white free-flowing powder. In dry-mix mortar manufacturing, it functions as an organic co-binder that redisperses to form a polymer film during hydration and drying. The grade is used where low-temperature film coalescence, adhesion to dense substrates, and water-immersion resistance are specification drivers. The designation differentiates the standard N-series stabilizer system from hydrophobizing and specialty-stabilized grades in the VINNAPAS range.
Physical handling and metering on production-scale dry-mix lines depend on bulk density, sieve residue, and moisture uptake. On twin-shaft compulsory mixers with working capacities of 500–2,000 L, batch-to-batch variation in bulk density is controlled by gravimetric loss-in-weight feeders rather than volumetric screw feeders. A polymer dosing tolerance of ±0.5 wt% of the dry-mix formula is commonly applied because deviations above this level can shift water-immersion adhesion results beyond routine test repeatability. The exact setpoint must be derived from the final formulation and not from the powder specification alone.
Representative production-control values for VINNAPAS 5710 N are listed in Table 1. The values are typical ranges reported in technical data sheets and are not certified lot-specific specification limits. The limiting film-formation condition is a minimum film-forming temperature of 0 °C measured according to ISO 2115. The glass transition temperature determined by differential scanning calorimetry according to ISO 11357-2:2020 is approximately −7 °C.

The pH of the redispersed powder is mildly neutral to slightly alkaline and does not represent free alkali content; it results from the protective colloid and residual salts from polymerization. The ash content is not a simple extender addition but derives from inorganic components in the dispersion and contributes to powder flow and anti-caking behaviour. The residue on the 400 µm sieve is a dry-mix homogeneity control point. Material retained on the sieve should not be ground into the batch, because mechanical fracture of the agglomerates can release internal moisture and reduce redispersibility.
Redispersibility in water is not defined by a single ISO method. In laboratory evaluation, the powder should form a stable dispersion at 20 °C under low-shear propeller agitation at 500 rpm within 30 s. Lump formation after this interval indicates moisture damage or excessive storage temperature. Water resistance of the final mortar must be tested on the cured formulation, not inferred from the polymer dispersion alone.
During curing, the vinyl acetate-ethylene copolymer redisperses into primary particles and coalesces as free water is consumed by cement hydration. The glass transition temperature of approximately −7 °C supports film formation at ambient temperatures without coalescent addition. Ethylene units lower the minimum film-forming temperature and reduce hydrophilic character relative to vinyl acetate homopolymer, while vinyl acetate segments contribute adhesion to inorganic surfaces. The minimum film-forming temperature is not identical to the glass transition temperature because the polyvinyl alcohol colloid plasticises the particle surface under humid conditions. At relative humidity above 80%, film formation proceeds more readily, but water sensitivity may increase until cement hydration immobilises the film.
The practical addition range for VINNAPAS 5710 N in cementitious tile adhesives is 2.0–4.5 wt% based on dry mortar mass. At the lower bound, wet adhesion improves but deformability may remain insufficient for C2S1 or C2S2 classification under ISO 13007-1:2014. At 4.0 wt%, transverse deformation and water-immersion adhesion increase, but open time and wet mortar viscosity can change unless the water-to-solids ratio and cellulose ether dosage are rebalanced. The powder redisperses in alkaline cement paste and forms a continuous film during drying; defoamer selection is often necessary because the polyvinyl alcohol colloid stabilises fine air in high-shear mixing.
Laboratory mixing according to EN 196-1:2016 uses a planetary mixer with low-speed dry homogenization followed by water addition and wet mixing at 140 rpm for 60 s. After a maturing period of 3 min, remixing is performed for 15 s. For production-scale rheological control, a rotational viscometer with a vane spindle can be used to compare torque response at 0.5 rpm and 5 rpm; the ratio between the two torque values provides a thixotropy index that is sensitive to polymer dispersion state. If high-shear dispersers above 1,000 rpm are used, entrained air volume can rise by several volume percent, and wet density should be monitored against a formulation-specific target. Published quantitative viscosity curves for this specific VAE grade are limited; full-scale trials are required because aggregate origin, cement phase composition, and cellulose ether quality interact with the redispersed polymer.
Air void content in polymer-modified mortars can increase from below 5 vol% to above 15 vol% without defoamer control. Air content is measurable by ASTM C185-20 or EN 1015-7. Polyglycol defoamers at 0.1–0.5 wt% of dry mortar can reduce entrained air without necessarily disrupting polymer film formation, but excessive defoamer dosage may lower water-immersion adhesion. The formulation must be adjusted so that wet density remains within the target range of approximately 1.60–1.80 kg/L for C2 mortars, with the exact target dependent on aggregate density and cement content.
In a typical C2 cementitious adhesive, cement content often lies in the range 30–40 wt%, graded sand 50–60 wt%, cellulose ether 0.3–0.7 wt%, and VINNAPAS 5710 N 2.0–4.0 wt%. For C2 classification under ISO 13007-2:2013, tensile adhesion strength after water immersion, heat ageing, and freeze-thaw conditioning must remain at or above 1.0 N/mm², and open time after 30 min must meet the standard’s minimum adhesion. The powder contributes to water immersion performance by lowering film sensitivity to moisture and by improving adhesion to dense tiles.
Outside tile adhesives, the grade is used in cementitious patching mortars, crack-bridging slurries, and repair mortars exposed to intermittent water contact. In such systems, flexural strength measured by EN 196-1 or ASTM C348 increases relative to an unmodified mortar, while compressive strength may plateau or decrease at dosages above 3.0 wt% because the continuous polymer phase modifies stress distribution. Tensile elongation of free films formed from redispersed VINNAPAS 5710 N can be measured by ISO 527-2:2012; published free-film data for this specific grade are limited and should be generated on the final formulation under controlled 23 °C and 50% relative humidity conditions.
In one-component cementitious waterproofing slurries, addition rates up to 5.0 wt% are sometimes used. Crack-bridging performance must be confirmed on the fully formulated slurry by the relevant liquid-applied waterproofing product standard, such as EN 14891:2017, because the polymer alone does not define system deformability. Self-leveling underlayment use is possible but not the primary application; if used, dosages are generally limited to 1.0–2.0 wt% to avoid excessive flexural modulus reduction and surface softness.
Substitution of VINNAPAS 5010 N with VINNAPAS 5710 N is appropriate where the hardened mortar must accommodate substrate movement or where adhesion after water immersion is critical. VINNAPAS 5010 N, with a higher glass transition temperature of approximately 16 °C and a minimum film-forming temperature near 4 °C, contributes higher modulus and surface hardness. VINNAPAS 5710 N, at approximately −7 °C and 0 °C respectively, reduces stiffness and increases elongation at break. Consequently, the 5710 N grade is selected for flexible C2S1 and C2S2 tile adhesives, while 5010 N is retained in rigid repair mortars and self-leveling underlayments where surface hardness and compressive strength are primary.
| Property | VINNAPAS 5710 N | VINNAPAS 5010 N |
| Glass transition temperature, DSC, ISO 11357-2 | approx −7 °C | approx 16 °C |
| Minimum film-forming temperature, ISO 2115 | 0 °C | approx 4 °C |
| Film character | Flexible, lower modulus | Harder, higher modulus |
| Primary use | Flexible tile adhesives, crack-bridging slurries | Rigid repair mortars, self-leveling underlayments |
Compared with VINNAPAS 5044 N, the 5710 N grade is selected when water-immersion adhesion rather than general-purpose flexibility is the specification driver. The products overlap in minimum film-forming temperature but differ in ethylene balance and stabilizer distribution; formulators should not assume equivalent dosage-response. Comparative evaluation should include ISO 13007-2 water immersion, heat ageing, and freeze-thaw cycles at the target addition rate. Unlike hydrophobizing VAE grades or organosilicon-modified powders, VINNAPAS 5710 N does not provide capillary water repellency by itself; waterproofing claims require a separate water repellent or a hydrophobizing powder grade.
Compared with styrene-butadiene rubber redispersible powders, the VAE grade has a different backbone unsaturation profile and therefore different UV ageing behaviour. In cementitious mortars, UV exposure is limited by the opaque mineral matrix, but exposed slurry coatings can show property drift that should be evaluated under accelerated weathering. Compared with polyvinyl acetate homopolymer powders, the ethylene-modified VAE structure reduces hydrolysis sensitivity in alkaline cement paste. Selection against acrylic or vinyl acetate-versatate powders must be based on formulation-specific tensile adhesion, water immersion, and deformability data rather than glass transition temperature alone.
Formulation boundaries must be observed when combining VINNAPAS 5710 N with cellulose ethers, accelerators, and superplasticizers. High-retention cellulose ethers may increase water demand and delay film coalescence, while strong liquefying admixtures can increase segregation unless the powder dosage and water-to-solids ratio are adjusted. Dry blending should avoid mixer jacket temperatures above 40 °C; prolonged shearing at elevated temperature may plastify powder on mixer blades and shafts. Bags should be stored in sealed conditions below 30 °C and 70% relative humidity; moisture uptake above the original value can cause caking and loss of redispersibility. In silo storage, the powder should be treated as an organic dust, with explosion protection documentation prepared according to applicable ATEX requirements.
Under EU CLP Regulation 1272/2008, VINNAPAS 5710 N is not classified as a hazardous substance or mixture in its supplied powder form. The current safety data sheet should be consulted for occupational exposure limits for respirable dust and for dust explosion parameters relevant to silo handling. The product is not intended for solventborne coatings, thermoplastic melt compounding, or applications where the polymer must remain unreactive with hydraulic binders. In gypsum-based systems, the effect of polyvinyl alcohol on setting retardation and crystal nucleation must be evaluated with the specific gypsum source; published data for this specific configuration is limited.
