VINNAPAS® EP 3888

1 of 218 products in this brand
VINNAPAS® EP 3888 is an aqueous polymer dispersion based on vinyl acetate and ethylene. It is produced without the use of alkyl phenol ethoxylate (APEO)-containing compounds. The dispersion exhibits excellent binding properties, very high scrub resistance, and exceptional hiding power. It also provides very good color development and stability.

Chemical Family: Vinyl Acetate Ethylene (VAE) Copolymer

Features: Abrasion Resistance, Excellent Pigment Binding Capacity, Frost Resistance, Good Color Stability, Improves Coating Hiding Power , Low Odor, Tack-free

Application Details

VINNAPAS® EP 3888 has an exceptionally high binding power and is highly recommended as a binder for indoor-paints and dispersion based indoor-plasters. It can also be used as a binder for exterior paints and dispersion based plasters. Due to its minimum film forming temperature of approx. +2°C VINNAPAS® EP 3888 doesn’t need any coalescence aids for filming.

Storage & Handling

Shelf Life
6 Months
Storage Information
  • When the dispersion is stored in tanks, proper storage conditions must be maintained. The product has a shelf life of 6 months starting from the date of manufacture if stored in the original, unopened containers at temperatures between 5 and 30°C. 
  • Iron or galvanized-iron equipment and containers are not recommended because the dispersion is slightly acidic. Corrosion may result in discoloration of the dispersion or its blends when further processed. Therefore, the use of containers and equipment made of ceramics, rubberized or enameled materials, appropriately finished stainless steel, or plastic (e.g. rigid PVC, polyethylene or polyester resin) is recommended.
  • As polymer dispersions may tend to superficial film formation, skins or lumps may form during storage or transportation. Filtration is therefore recommended prior to utilization of the product.

Preservation for Transport, Storage and further Processing

  • The product is adequately preserved during transportation and storage if kept in the original, unopened containers. However, if it is transferred to storage tanks, the dispersion should be protected against microbial attack by adding a suitable preservative package. Measures should also be taken to ensure cleanliness of the tanks and pipes. In unstirred tanks, a layer of preservative-containing water should be sprayed onto the surface of the dispersion to prevent the formation of unwanted skin and possible attack by microorganisms.
  • The thickness of this water layer should be < 5 mm for low viscosity dispersions and up to 10-20 mm for high viscosity products. Proper procedures - periodic tank cleaning and sanitization - must be set up in order to prevent microbial attack. Contact your biocide representative/supplier for further plant hygiene recommendations.
  • Measures should be taken to ensure that only clean air enters the tank when the dispersion is removed. Finished products manufactured from polymer dispersions usually also require preservation.
  • The type and scope of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility with other components and the efficacy of the preservative should always be tested in the respective formulation. Preservative manufacturers will be able to advise you about the type and dosage of preservative required.
