Composite coating for imparting particle erosion resistance

摘要

Erosion resistant coating compositions comprising a poly(Bisphenol A-co-epichlorohydrin) glycidyl end-capped component, an active hydrogen compound, a linear siloxane and a silsesquioxane. Protective coatings formed from such a composition impart particle-erosion resistance to parts having such a coating disposed on some portion of their surface.
