Abstract:
1. A single-component coating composition comprising: an N-substituted urea polymer with extended chains and terminal alkoxysilanes, wherein said polymer is a reaction product of (a) an aliphatic polyisocyanate, (b) an N-substituted amino-functional alkoxysilane, and (c) a secondary diamine chain extender, wherein no unreacted isocyanate remains in said polymer, wherein the composition additionally comprises a reactive diluent comprising a polysiloxane with at least 2hydrolyzable alkoxysilane groups, a hydroxyl-functional polysiloxane, an alkyl-functional alkoxysilane, a polysiloxane-urea polymer with hydrolysable alkoxysilane groups, an aliphatic or cycloaliphatic N-substituted urea with hydrolyzable alkoxysilane groups, a polyester-urethane polymer with hydrolyzable alkoxysilane groups, or any combination thereof.
