- Application Details
- 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.

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.
