Wacker Vinnapas® SAF 34 Styrene/Acrylate Copolymer
Categories: Polymer; Thermoplastic

Material Notes: Product description: VINNAPAS® SAF 34 is a fine-particle dispersion of a special styrene/acrylate copolymer. It is free from alkyl phenol ethoxylate (APEO) containing compounds.

Application: VINNAPAS® SAF 34 has an excellent pigment-binding capacity and very good adhesion to inorganic substrates. VINNAPAS® SAF 34 has proved for many years to be an outstanding binder in many fields of application and versatility is its special strength. VINNAPAS® SAF 34 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 34 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. VINNAPAS® SAF 34 is an outstanding binder for exterior masonry paints which show very low dirt pickup. Conventional masonry paints are frequently formulated below the critical pigment volume concentration (CPVC) but silicone resin paints must be permeable to water vapor and therefore should be formulated above the CPVC. WACKER silicone masonry water repellants like SILRES® BS 45 and SILRES BS® 1306 show good compatibility with VINNAPAS® SAF 34 and silicone resin paints containing VINNAPAS® SAF 34 exhibit excellent water repellency and low capillary water absorption. If VINNAPAS® SAF 34 is to be used in dispersion silicate paints, the compatibility with the corresponding water glass should always be checked. VINNAPAS® SAF 34 is particularly recommended for producing pasty construction adhesives, which must have outstanding strength even when exposed to water. This improved wet adhesion is particularly useful for ceramic tiles adhesives.
