As an accredited Vinavil 153 factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Vinavil 153 is supplied in 200 kg polyethylene-lined steel drums, with 1,000 kg IBC containers also available. |
| Container Loading (20′ FCL) | Vinavil 153 is loaded in a 20′ FCL on pallets, shrink-wrapped, secured, and protected from moisture for safe transport. |
| Shipping | Vinavil 153 is an aqueous vinyl acetate homopolymer dispersion, generally non-hazardous for transport. Ship in sealed, leak-proof drums, protected from freezing and extreme heat. Avoid prolonged storage above 35°C. No special dangerous-goods labelling is normally required, but secure loads properly and keep containers dry and upright. |
| Storage | Store Vinavil 153 in its original, tightly sealed container in a cool, dry, well-ventilated area. Protect from freezing and direct sunlight; ideal temperature 5–30°C. Keep away from heat sources and incompatible materials. Avoid prolonged skin contact. Use within manufacturer’s stated shelf life, stirring gently before use. |
| Shelf Life | Shelf life is 12 months from production date when stored in sealed original containers between 5–35°C, protected from frost. |
In cold-press lamination of 0.6 mm rotary-cut beech veneer to 18 mm medium-density fibreboard, Vinavil 153 is typically adjusted with 2–5 phr water and post-hardened using a 20 wt% aluminium chloride hexahydrate solution at 3–6 phr based on wet dispersion mass. The hardener shifts the EN 204 water-resistance class from D2 toward D3 but shortens pot life and narrows the processing window. A formulation at 100 phr Vinavil 153, 4 phr hardener solution, and 3 phr water shows open assembly time of 8–12 min at 20 °C and 50 % RH. Doctor-bar application at 0.20 mm wet film gives 120–150 g/m² adhesive coverage. Cold pressing at 0.4–0.7 MPa for 30 min followed by 24 h conditioning at 20 °C produces fibre-tear values above 70 % on EN 204 D2 specimens, while D3 pass rates require post-assembly curing at 23 °C for 7 days. Processing boundaries include skinning after 45 min in an open glue pan at 35 °C and thickening above 2,000 mPa·s when hardener addition exceeds 6 phr. Lamination on a rotary press with a 0.5 mm roll gap is prone to strike-through if coating weight exceeds 160 g/m². The end product is a short-cycle furniture panel with primary VOC emission controlled under CDPH Standard Method v1.2 and adhesive classification tested according to EN 204:2016 durability classes.
When 35 wt% of 5 µm ground calcium carbonate is dispersed into the dispersion, the filler compacts the wet adhesive and limits squeeze-out on short compression sections. A low-cost side-seam blend contains 100 phr Vinavil 153, 45 phr GCC, 0.2 phr polyacrylate thickener, and 0.1 phr mineral-oil defoamer. Mixing is carried out in a 50 L planetary dissolver with a butterfly blade at 450 rpm for 15 min; filler addition above 45 phr increases Brookfield RVT viscosity from 12,000 mPa·s to 25,000 mPa·s and creates clean-up bottlenecks on transfer rollers. Application on a side-seam line at 80–120 m/min uses a 0.5 mm nozzle orifice under 0.3–0.6 MPa air pressure. Open time at 25 °C and 60 % RH is 3–6 s, after which compression at 0.2 MPa must produce fibre tear on ECT-grade liners. For indirect food packaging, adhesive selection is governed by FDA 21 CFR 175.105 component clearance or EU 10/2011 migration limits where no functional barrier exists. The end product is a regular slotted case with seam burst resistance controlled by ISO 3037; adhesive failure is monitored as fibre tear below 80 % on kraft liner.
The following table records starting-point plant observations under one set of conditions; published reproducibility data for this specific configuration is limited.
| GCC loading (phr) | RVT viscosity (mPa·s) | Wet open time (s) | Fibre tear after 4 s compression (%) |
|---|---|---|---|
| 25 | 8,000–10,000 | 4–6 | 70–80 |
| 35 | 12,000–15,000 | 3–4 | 80–95 |
| 45 | 20,000–25,000 | 2–3 | 60–75 |
On a spiral tube winder running 25 m/min with 120 N web tension on recycled linerboard, the dispersion is diluted to 2,000–3,000 mPa·s to avoid slinging at the gravure transfer point. A working pot mix uses 100 phr Vinavil 153, 8–12 phr water, 0.15 phr silicone-free defoamer, and 0.1 phr benzisothiazolinone-based biocide. The adhesive is circulated through a 40 µm screen and applied by a gravure roll with 0.08 mm cell depth. Wet film weight is held at 12–18 g/m²; above 20 g/m² the outer plies show washboard marks at the knife. Splicing at 18 °C and 55 % RH yields green bond sufficient for rewinding within 6 s. Below 12 °C film formation is retarded because the minimum film formation temperature of the homopolymer is approached. The end product is a 70 mm inner diameter spiral-wound core for label stock; dimensional stability is checked by concentricity tolerance of 0.8 mm across a 1,000 mm length. Regulatory restrictions for industrial supply include REACH Annex XVII screening and absence of Substances of Very High Concern above the candidate-list threshold.
Perfect binding lines operating at 7,000 cycles/h expose the dispersion to high shear at the nipping point between side clamps and the book block; a backbone adhesive based on Vinavil 153 is therefore thickened to 4,000–6,000 mPa·s. A formulation for softcover adhesive binding uses 100 phr Vinavil 153, 4–8 phr triacetin or acetyl tributyl citrate, 0.3 phr high-shear associative thickener, and 2 phr water. The plasticizer reduces the film-forming temperature and improves flexibility of the dried spine. Above 8 phr plasticizer the dried film shows creep at stack temperatures above 35 °C and pages can separate in accelerated peel testing. Application is by roller to the milled spine at 0.15–0.25 mm wet film, followed by 2–4 s pressing in a nipping station at 0.1 MPa; an infrared tunnel at 50–60 °C removes water to a moisture content below 1.5 % before casing-in. Clean-up uses water below 30 °C to avoid coalesced deposits on adhesion-tape guides. The end product is a perfect-bound paperback with peel strength of at least 4 N/cm after 24 h conditioning at 23 °C and 50 % RH when tested on uncoated book paper according to ASTM D 903-98. Compliance for schoolbooks in Europe is evaluated under REACH Annex XVII entry 51 for phthalates when plasticized grades are used; triacetin and acetyl tributyl citrate are selected to avoid phthalate triggers.
Vinyl-coated wallcovering installation in corridor applications uses a high-solids dispersion carrying 20–30 phr water and 5–10 phr bentonite clay or cellulosic thickener. The adhesive mass is spread with a 0.5 mm notched trowel, giving 250–350 g/m² wet coverage on gypsum board primed to 0.2 g/cm³ surface density. Open time at 20 °C and 40 % RH is 20–30 min, allowing repositioning of the wallcovering. Above 60 % RH the open time shortens to 10–15 min and the risk of blisters under semi-rigid vinyl increases. The dried film must retain enough water redispersibility for dry-stripping; complete coalescence is undesirable. Slip resistance is assessed on site by the pendulum friction tester specified in EN 13036-4 for surface condition monitoring, with a minimum acceptable value determined by the building specification. VOC emissions from the installed adhesive are evaluated by chamber testing under CDPH Standard Method v1.2; plasticizer-free PVAc systems typically show 3-day chamber concentrations below 1,500 µg/m³ total VOC. Heavy metals migration from the dried film is tested by EN 71-3 when the wallcovering is installed in children’s environments. The end product is a vinyl-coated wallcovering in hospitality and healthcare corridors with a dry-strippable adhesive interlayer that must not fracture the gypsum board surface during removal.

An aqueous dispersion of a vinyl acetate homopolymer stabilized with a polyvinyl alcohol protective colloid, Vinavil 153 is supplied as a solvent-free, medium-viscosity liquid for use in paper and packaging adhesives, wood assembly, and laminating operations. The model designation Vinavil 153 identifies a specific production grade within the Vinavil aqueous dispersion range. It is categorized as a thermoplastic, non-structural adhesive when tested under EN 204:2016. The material is characterized by a non-volatile content of 50 ± 1% when measured in accordance with ISO 3251:2019 using a forced-air oven at 105 °C for 2 h, a pH of 4.0–5.5 at 25 °C under ISO 976:2013, and a Brookfield viscosity at 25 °C of 2,500–5,000 mPa·s when tested with RVT spindle 4 at 20 rpm in accordance with ISO 2555:2018. Density at 25 °C is 1.07–1.10 g/cm³ by ISO 2811-1:2016, and minimum film formation temperature is 15–18 °C according to ISO 2115:1996. Residual vinyl acetate monomer is controlled below 0.1% by gas chromatography. These values are representative production-control ranges; the lot-specific certificate of analysis should be consulted for exact batch data.
| Property | Test method | Typical range | Unit |
|---|---|---|---|
| Non-volatile content | ISO 3251:2019 | 50 ± 1 | % |
| pH at 25 °C | ISO 976:2013 | 4.0–5.5 | — |
| Brookfield viscosity | ISO 2555:2018 | 2,500–5,000 | mPa·s |
| Density at 25 °C | ISO 2811-1:2016 | 1.07–1.10 | g/cm³ |
| Minimum film formation temperature | ISO 2115:1996 | 15–18 | °C |
Within the dispersion, the dispersed phase consists predominantly of polyvinyl acetate with a polymer-backbone glass transition temperature in the 28–33 °C range. The continuous aqueous phase is stabilized by polyvinyl alcohol, a nonionic protective colloid that provides shear-thinning rheology and wet tack on cellulose-based surfaces. The dispersion exhibits pseudoplastic flow: apparent viscosity decreases as shear rate increases from 5 rpm to 100 rpm on a Brookfield RVT spindle, a response that favors roller transfer but can produce strike-through if the formulation is overdiluted. Typical particle size is in the 0.5–2.0 µm range by laser diffraction, and the particle size distribution is broad. The presence of polyvinyl alcohol affects film water sensitivity; immersion in water reduces bond strength unless the formulation includes crosslinking additives. The pH range of 4.0–5.5 maintains colloidal stability, while alkaline additives may increase viscosity or induce gelation. The grade may contain minor process additives such as preservatives and defoamers; the safety data sheet lists the production-site additive package. Published data for the exact particle-size distribution under production-line conditions is limited; the stated range should be confirmed per batch with a Malvern Mastersizer or equivalent laser-diffraction instrument.
In paper sack, folding carton, and side-seam lamination, Vinavil 153 is applied with wheel, extrusion-nozzle, or engraved-roller systems. On corrugated board lines running at 40–80 m/min, wet film deposition of 80–150 µm is used to balance open time and initial tack. Field data from rotary side-seam equipment indicate that Brookfield viscosity is often adjusted to 1,800–2,500 mPa·s at 25 °C by adding 3–5 wt% deionized water; below 1,200 mPa·s, strike-through on 70 g/m² kraft becomes problematic, while above 3,000 mPa·s transfer is incomplete and adhesive buildup on doctor blades increases. Open time at 23 °C and 50% RH is 5–10 min for porous board, allowing machine stops without premature skinning. Bond formation is evaluated by EN 205:2016 tensile shear testing or ISO 1924-2:2008 tensile strength measurements on bonded substrates. The polyvinyl alcohol-stabilized dispersion demonstrates high adhesion to uncoated paperboard, clay-coated board, and sulfate kraft, but adhesion to corona-treated polyethylene film is lower than vinyl acetate-ethylene grades. For film-to-paper lamination, corona treatment at 38–42 mN/m surface energy is normally required, and bond strength should be validated at the specified machine speed. Published data for rotary die-cutting of 300 g/m² clay-coated board with this specific grade is limited; line trials should define the exact adhesive weight.
Storage at 5–30 °C in sealed original containers is required. Freeze-thaw cycling causes irreversible particle agglomeration because the polyvinyl alcohol protective layer is disrupted during ice-crystal growth; frozen product must be rejected if sedimentation or grit is visible after thawing. Shelf life is typically 12 months from production in unopened containers. Before use, product withdrawn from storage should be gently homogenized with low-shear mixing such as a paddle agitator at 20–50 rpm. High-shear dispersion with a dissolver disk above 800 rpm may generate foam and increase apparent viscosity. Rotary lobe and centrifugal pumps should be replaced by diaphragm or peristaltic transfer pumps to avoid shear-induced instability.
The product is incompatible with high concentrations of polyvalent metal ions, cationic wetting agents, and lower aliphatic alcohols such as ethanol or isopropanol above 5–10 wt%; these can induce coagulation or a sharp viscosity rise. pH adjustment should remain between 3.0–8.0. Borax and other borate anions complex with polyvinyl alcohol and should not be used unless a controlled increase in tack is specifically formulated and viscosity is checked after 24 h. Equipment contact surfaces may be stainless steel, high-density polyethylene, or polypropylene; mild steel is not recommended because iron ions can darken the film. The material is non-flammable under CLP Regulation (EC) No 1272/2008 and is not classified as acute hazardous; spill containment should nevertheless follow site wastewater protocols for polymer dispersions. The product must not be discharged to surface water without coagulation and removal of suspended solids.
When beech, pine, or poplar adherends are bonded with Vinavil 153, the moisture content of the wood should be maintained at 8–12% to avoid delayed curing or excessive substrate swelling. Glue spread rates of 120–200 g/m² are common for cold-press laminating; open assembly time at 20 °C and 65% RH is limited to 5–10 min, while closed assembly time should not exceed 15–20 min. Press pressure of 0.5–1.0 MPa is applied for 30–90 min depending on wood density and adhesive weight; panels should be conditioned at 23 °C and 50% RH for 7 days before destructive testing. Joints produced under these conditions are typically assigned to durability class D2 or D3 under EN 204:2016, provided they meet the minimum tensile shear strengths defined in the standard. The product is not a load-bearing structural adhesive under EN 302-1:2013 and is not rated for D4 exterior exposure unless formulation with a suitable crosslinker is validated. In high-frequency curing equipment, dielectric heating may accelerate water removal but may also generate steam pockets; radio-frequency press settings should be reduced compared with solvent-borne PVAc adhesives. Batch-to-batch adhesive performance is monitored by tensile shear on beech strips per EN 205:2016. Published data for red oak and tropical hardwood species with this specific grade is limited; high extractive content can retard wetting and requires pre-cleaning or primer evaluation.
Film integrity depends on the minimum film formation temperature of 15–18 °C determined by ISO 2115:1996. At application temperatures below the MFFT, the dispersion particles do not coalesce into a continuous film, and dried adhesive layers appear white and powdery. In unheated plants operating below 15 °C, substrates should be warmed to at least 18–20 °C or a temporary coalescent should be used. Once coalesced, the polyvinyl acetate film has a glass transition temperature of 28–33 °C and develops high dry tensile strength but limited low-temperature flexibility. Drying rate at 23 °C and 50% RH is governed by water loss from the edge and surface; a wet film of 100 µm typically reaches a clear film within 10–20 min. The addition of plasticizers such as dibutyl phthalate or citrate esters lowers MFFT and increases flexibility but reduces bond strength and heat resistance. Any plasticizer addition should be validated by ISO 527-1:2019 tensile testing or EN 205:2016. The homopolymer film is soluble in lower alcohols and partially swells in water; it resists aliphatic hydrocarbons but should not be used where continuous solvent immersion is specified.
Relative to vinyl acetate-ethylene (VAE) dispersions, Vinavil 153 exhibits a higher glass transition temperature and a less flexible polymer backbone. VAE grades with ethylene contents of 10–25 wt% have lower minimum film formation temperatures and improved adhesion to low-energy polymer films, but they usually show lower dry heat resistance and higher tack under heat. Vinavil 153 gives fast wet tack and high dry strength on porous paperboard and wood, but its water resistance is lower than VAE or vinyl acetate-vinyl chloride (VAc-VC) grades. VAc-VC dispersions provide better solvent and water resistance because of the vinyl chloride comonomer, but they require strict handling and may carry higher regulatory burden. Compared with solvent-borne polyvinyl acetate systems, the aqueous dispersion reduces volatile organic compound emissions and eliminates solvent-handling controls. Substitution is not a direct drop-in; pot life, open time, and bond strength must be revalidated under EN 205:2016 or ASTM D1876-08 depending on the application.
| Performance dimension | Vinavil 153 | VAE dispersion | VAc-VC dispersion |
|---|---|---|---|
| Polymer backbone | PVAc homopolymer | Vinyl acetate-ethylene | Vinyl acetate-vinyl chloride |
| Glass transition temperature | 28–33 °C | -15 to +15 °C depending on ethylene content | Grade-dependent, typically higher than homopolymer |
| Minimum film formation temperature | 15–18 °C | 0–10 °C | Grade-dependent |
| Adhesion to porous substrates | High | Moderate to high | Moderate |
| Water resistance under EN 204:2016 | D2/D3 typical | D3/D4 achievable | D4 achievable |
| Low-temperature flexibility | Lower | Higher | Lower to moderate |
| VOC profile | Low | Low | Low, with chloride handling controls |
The dispersion falls under REACH Regulation (EC) No 1907/2006 as a polymer with registration obligations for imported monomers. It is classified in accordance with CLP Regulation (EC) No 1272/2008; no acute toxicity, flammability, or environmental hazard classification is assigned in the typical safety data sheet. For food contact, the product may be considered for use in packaging adhesives under FDA 21 CFR 175.105 if the adhesive is separated from food by a functional barrier or if migration limits are met; specific food-contact approval must be confirmed with the manufacturer’s compliance statement. The grade is not intended for medical device applications under ISO 10993-1:2018 without biocompatibility testing. Heavy metal content is controlled under typical adhesive industry specifications; test reports may include lead, cadmium, mercury, and hexavalent chromium below 10 ppm each. The product contains no intentionally added formaldehyde, but preservative and defoamer packages vary by production site and must be listed on the safety data sheet. For European Ecolabel or Nordic Swan compliance, the formulation’s preservatives and residual monomer levels should be checked against the relevant criteria.
