VINNAPAS® EAF 730
VINNAPAS® EAF 730 is a polymer dispersion based on vinyl ester, ethylene and acrylic acid ester. It is characterized by its very good hydrophobic properties combined with an excellent color stability.
- Excellent cost-in-use compared to alternative high-end technologies
- Perfectly spans all PVC levels (30% – 90%)
- Very good hydrophobicity
- Outstanding color stability and compatibility even with sensitive organic pigments
- Higher inherent flame retardancy than standard acrylic systems
- Very good film-forming properties
- Very good scrub resistance
- High blocking resistance
- Very low dirt pick-up
- Excellent saponification resistance
- Very good compatibility with cement
- Produced without the use of APEOs
The principal feature of VINNAPAS® EAF 730 is its wide range of uses in coating systems containing opacifying pigments. Versatility is its special strength.
VINNAPAS® EAF 730 is particularly recommended to produce masonry paints with good hiding power and great flexibility.
Thanks to its good resistance to saponification, VINNAPAS® EAF 730 can be employed as the organic polymer component of organo-silicate paints and renders. To ensure a good shelf life, the formulation must be carefully built around the binder.
Due to its minimum film forming temperature of approx. +3°C VINNAPAS® EAF 730 does not need any coalescing aids for filming, thus it is a very suitable binder for paints which complies with the criteria of tighter environmental-labels.
VINNAPAS® EAF 730 has proved itself as an excellent binder for resin bound plasters, especially in external thermal insulation composite systems with rendering (ETICS). In such a system, VINNAPAS® EAF 730 can also be used as binder for the base coat. Hence, only one binder is needed for the entire system.
The dispersion is readily compatible with Portland cement and its setting behavior is hardly influenced. As a consequence, water resistance of the base coat can be increased.
Due to the low calorific value of VINNAPAS® EAF 730, correctly installed ETICS with this composition fall under Fire Class A2 as per EN 13501.
VINNAPAS® EAF 730 is also a suitable binder for silicone resin emulsion paints (SREP) as well silicone renders.

When the dispersion is stored in tanks, proper storage conditions must be maintained. VINNAPAS® EAF 730 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. 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
VINNAPAS® EAF 730 is adequately preserved during transportation and storage if kept in the original, unopened containers. When stored in tanks, the dispersion should be modified with a preservative to prevent microbial contamination. Suitable measures should be taken to ensure that the tanks are properly clean. In storage tanks in which the product is not stirred, it is advisable to cover the surface of the dispersion with 1 - 2 cm of water, to which a preservative has been added. This will prevent skin formation and microbial contamination. In the case of storage in silos, it is important that the air drawn into the silo when the product is discharged is also kept free of germs. As a rule, all finished products manufactured from polymer dispersions also require preservation. The type and extent of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility and effectiveness of the preservatives should be checked for a given formulation. Preservative manufacturers will be able to advise you on the type and amount of conservation agent to use.
