SiSiB® PC1951 is a colorless to slight yellowish liquid with a light amine-like odor, that is soluble in alcohols, and aliphatic or aromatic hydrocarbons. It is a bifunctional organosilane possessing a reactive secondary amino group and hydrolyzable inorganic trimethoxysilyl groups. It can be used as a primer or additive and for the chemical modification of sealants and adhesives; as a size constituent or finish for glass fiber/glass fabric composites; as an additive to phenolic, furan and melamine resins used in foundry resins; for pretreatment of fillers and pigments used in mineral-filled polymers; as a primer and additive to improve the adhesion of paints and coatings to the substrate; as an endcapper for polyurethanes; or as starting material in the synthesis of amino-functional silicones.
SiSiB Silicones has more than 20 years’ experience in manufacturing various silicone materials. They have established six factories in China to manufacture organofunctional silanes (silane coupling agents, silane crosslinkers, silane blocking agents), silicone fluids (straight, modified), silicone rubbers (Gum, HTV, RTV and LSR), silicone resins and fumed silica.
SiSiB® silanes are widely used in adhesives and sealants to improve environmental resistance, increase adhesion and other mechanical properties and can be used to improve the adhesion of many coatings (urethanes, epoxies, phenolics and others) to glass and metal surfaces for the paint and coating industry.
