- Application Details
- VINNAPAS® SAF 72 has an excellent pigment-binding capacity and very good adhesion to inorganic substrates.
- VINNAPAS® SAF 72 is a high performance binder for interior and exterior paints, dispersion modified silicate paints and plasters, silicone paints and plasters, synthetic resin bound plasters and roof coatings.
- VINNAPAS® SAF 72 is an ideal binder for manufacturing construction and tile adhesive paste with extremely good wet adhesion properties. Films produced from this dispersion have an excellent resistance to water and alkalis, with only slight water absorption and greatly delayed whitening.
- Paints and plasters based on this dispersion therefore show very little tendency to soften under prolonged immersion in water. If VINNAPAS® SAF 72 is to be used in dispersion silicate paints, the compatibility with the corresponding water glass should always be checked.
Processing- Since VINNAPAS® SAF 72 only forms a film at temperatures over approx. 23°C, it must, in practice, be combined with a film-forming agent. Depending on its type, a dosage between 3 – 10 % of film-forming agent on VINNAPAS® SAF 72 is recommended.

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.
