Abstract
The present invention is directed to a method of mitigating ice build-up on a substrate, such as a wind blade, comprising applying to the substrate curable film-forming compositions comprising isocyanate-functional curing agents, film-forming compositions with functional groups reactive with the isocyanates, and polysiloxanes. The film-forming compositions can be applied directly to the surface of the substrate or onto a primer coat and/or topcoat on the substrate.
