Copolymerization of vinyl acetate with vinyl laurate yields copolymers that are more flexible than VINNAPAS® homopolymer resins. Properties: VINNAPAS® B 500/20 VL is pale yellow, transparent and has good light stability. Water absorption is lower and alkali resistance higher compared to VINNAPAS® homopolymer resins. A remarkable feature of VINNAPAS® copolymer resins is that they release solvent more quickly than other vinyl resins, e.g. VINNAPAS® homopolymers. VINNAPAS® copolymer resins are permanently flexible since they are internally plasticized. There is no separate plasticizing component to evaporate or migrate. VINNAPAS® B 500/20 VL is solid and plastic at room temperature and becomes very tacky at elevated temperatures. Manufacturer recommends incorporating an aging stabilizer if VINNAPAS® B 500/20 VL is subjected to prolonged exposure to high temperatures. Preliminary tests should be carried out as required. Application: Typical applications for VINNAPAS® B 500/20 VL: - adhesives
- lacquers
- gum base
