Abstract
Disclosed and claimed is a composition that comprises a dispersion in a solvent of a compound comprising the reaction product of (1) a polyamine in which a plurality of amine groups are bonded to at least one radical comprising alkylene or arylene groups that separate the polyamine nitrogen atoms by at least four intermediate atoms in a chain, and (2) a silane which carries a plurality of silicon-bonded hydrolysable groups, and a silicon-bonded organic group that is covalently reactive with and which bonds with an amine group, to provide a reaction product molecule which comprises an average of at least about 2.5 of said silane groups per molecule. Some of these materials show superior advantage as a paint primer and some provide excellent corrosion resistance.
