Properties of amino functional silane: It has two functional groups, amino and ethoxy. Among them, three hydrolyzable groups (ethoxy groups) are firstly hydrolyzed to form silanol in the reaction. Since silanol is unstable, it is easily combined with inorganic or metal hydroxyl groups to dehydrate and combine with inorganic substances or metals. Two active hydrogens on the amino group can react with various polymers to bond two completely different materials through chemical bonds.
