SiSiB® PC1951 is a bifunctional organosilane possessing a reactive secondary amino group and hydrolyzable inorganic trimethoxysilyl groups.
The dual nature of its reactivity allows SiSiB® PC1951 to bind chemically to both inorganic materials and organic silicone polymers, thus functioning as an adhesion promoter, surface modifier and as a reactant for product modification.
SiSiB® PC1951 is a colorless to slight yellowish liquid with a light amine-like odor, it is soluble in alcohols, and aliphatic or aromatic hydrocarbons. It is the equivalent of Evonik's Dynasylan 1189 silane.
