A novel new class of protective coatings has been developed which is based on the hybridization of inorganic siloxane polymers with organic epoxy polymers. These coatings exhibit the corrosion resistance of an epoxy and weathering resistance superior to the best aliphatic polyurethane. As a result, traditional high performance 3-coat inorganic zinc/epoxy/polyurethane coatings can be replaced with 2-coat zinc/epoxy siloxane coatings with significant savings in applied cost.
