Patent ID: 7057000

Claim:
A two-component coating composition consisting of a) a polyisocyanate component comprising NCO prepolymers produced by reacting one or more isocyanates with a polyether component at a NCO/OH equivalent ratio of 1.3:1 to 20:1, b) an isocyanate-reactive component selected from the group consisting of low and high molecular weight polyols, high molecular weight amine-functional compounds and high molecular weight polyaldimines that contain less than 0.5% by weight, based on the weight of component b), of an aromatic polyamine, c) 0.1 to 1.8 wt. %, based on the weight of components a) and b), of a compound containing at least one epoxy group and at least one alkoxysilane group, wherein a first component comprises a) and c) and a second component comprises b) and d) optionally one or more additives selected from the group consisting of solvents, catalysts, leveling agents, wetting agents, flow control agents, antiskinning agents, antifoaming agents, fillers, viscosity regulators, plasticizers, pigments, dyes, UV absorbers, stabilizers against thermal and oxidative degradation, and combinations thereof.
