VINNAPAS® EP 3360 (ULS)
VINNAPAS® EP 3360 (ULS) is an aqueous polymer dispersion based on vinyl acetate and ethylene. The dispersion is produced without the use of alkyl phenol ethoxylate (APEO) containing compounds.
- High solids content for formulation flexibility and supply-chain effciency
- Very high scrub resistance
- Excellent hiding power
- Low-odor and very-low-VOC (< 1 g/l)
All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence. This disclaimer of warranty and liability also applies particularly in foreign countries with respect to third parties' rights.
VINNAPAS® EP 3360 (ULS) 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. In paint applications it shows very high scrub resistance and high hiding power. Due to its minimum film forming temperature of approx. +2°C VINNAPAS® EP 3360 (ULS) doesn’t need any coalescence aids for film formation and is therefore suitable for formulation of very low VOC (<1g/l) and low odor paints.
If the product is used in applications other than those mentioned, the choice, processing and use of the product is the sole responsibility of the purchaser. All legal and other regulations must be complied with.

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EP 3360 (ULS) has a shelf life of 9 months from the date of manufacture if stored in the original, unopened containers at temperatures between 5 and 40 °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 be formed during storage or transportation. A filtration process is thus recommended prior to utilization of the product. If the product is stored for a longer period, stirring is recommended before use.
Preservation for Transport, Storage and further Processing
VINNAPAS® EP 3360 (ULS) 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.
