Abstract
Silane polymer coating compositions which have excellent bonding properties for metallic surfaces and which make such surfaces highly resistant to corrosion. The compositions are formed by anhydrously reacting an epoxy trialkoxy silane with a primary amino trialkoxy silane in a stoichiometric molar ratio which provides one epoxy group for reaction with each primary amino hydrogen site to form the silane polymer coating composition. The composition is applied to the metal surface, and is hydrolyzed and dehydrated in situ to crosslink thereon and bond to the surface to form the corrosion-resistant coating.
