VINNAPAS® eco EF 3777
VINNAPAS® eco EF 3777 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, organic solvents and plasticizers. Because VINNAPAS® eco EF 3777 has a low VOC content, it is suitable for the manufacture of low-emission products.
VINNAPAS® eco EF 3777 is a fossil resources saving product. Whenever this product is bought, up to 100% of the fossil-based raw materials required for manufacturing this product can be replaced by sustainably certified renewable feedstock. The replacement is based on the REDcert² mass balance approach, audited by TÜV Nord. The exact amount of fossil raw material replaced depends on the selected product version and is specified in the REDcert² certificate, which can be found on the product page on the WACKER website.
- Excellent pigment binding ability
- Very good scrub resistance
- Low blocking behavior in silk paint formulations
VINNAPAS® eco EF 3777 is designed to provide outstanding performances in interior paints flat to semi-gloss. Due to its low MFFT and low levels of residual monomers VINNAPAS® eco EF 3777 is especially recommended as binder for environmentally friendly decorative coatings.
The pigment binding ability is excellent. Hence, even with low amounts of binder high level of abrasive resistance of a coating can be achieved. The use of VINNAPAS® eco EF 3777 enables the production of interior coatings with low odor and free of intentionally added organic solvents, which provide high performance without compromises regarding environmental compatibility.

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 receipt if stored in the original, unopened containers at temperatures between 5 and 30 °C. Any longer periods for the maximum storage period that may be described in the Certificate of Analysis which accompanies each shipment of the product, take preference over this suggestion in which case the time period stated in the Certificate of Analysis shall be solely authoritative. Iron or galvanized iron containers and equipment are not recommended. Corrosion could result in discoloration of the dispersion or blends made from it in further processing. We therefore recommend the use of containers and equipment made of ceramic, rubberized or enameled materials, appropriately finished stainless steel, or plastic (rigid PVC, polyethylene or polyester resin). 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.
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.
