Abstract

This invention relates to new blocked isocyanate silicone resins which can be used to make shelf stable one part curable coating compositions. These coatings do not cure until heated. The coatings provide weather resistant protection for numerous substrates including automobile exteriors, leather fabric, electronic components, wood floors and surfaces.
