Polyvest OC 800 S Polynutadiene Degussa Polyolefins (PE, PP) SEALANT ADHESIVE POLYVEST OC 800 S is a maleic anhydride adduct of a low molecular weight 1.4-cis-polybutadiene. This polybutadiene adduct contains succinic anhydride groups randomly distributed along the polymer chain.The originally apolar butadiene is thus made more polar and accessible to various chemical reactions. POLYVEST OC 800 S is compatible with long-oil alkyd resins, rosin, resin esters and zinc resinates. POLYVEST OC 800 S has good electrical insulation properties and low-temperature stability. With these excellent properties, POLYVEST OC 800 S is employed as: Crosslinker component in 2-component systems e.g. in: sealing and adhesives compounds Polymeric chalk activator in rubber compounds, especially EPDM compounds Water-soluble, oxidatively drying binder Maleic anhydride adduct of polybutadiene. Used as crosslinker component in 2-component adhesives and sealants. Used also as polymeric chalk activator and water-soluble, oxidatively drying binder. Provides electrical insulation properties and low-temperature stability. Offers water and chemicals resistance. Compatible with long-oil alkyd resins, rosin, resin esters.
