| Introduction |
|
SiSiB® PC1951 is a bifunctional organosilane possessing a reactive 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 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 which soluble in alcohols, and aliphatic or aromatic hydrocarbons. |
