Product performance of amino silanes
It has two functional groups, amino and ethoxy. Three of the hydrolyzable groups (ethoxy groups) are first hydrolyzed to form silanols in the reaction. Since silanol is unstable, it is easily combined with dehydration of an inorganic substance or a hydroxyl group on a metal surface to be combined with an inorganic substance or a metal. Two active hydrogens on the amino group can react with various polymers to bond two completely different materials through chemical bonds.
