Abstract:
The present invention provides a polyurethane coating composition comprising a fluorosurfactant, a silane adhesion promoter, and a silane modified polyisocyanate, wherein the composition has excellent substrate wet-out and adhesion under direct wet-on-hot and cold spray applications. The coating composition is particularly well suited to use with polyurethane pultrusion composites.
