Abstract
Siloxane-polyester compositions comprising (1) a siloxane-polyester copolymer resin (2) one or more solvents for the siloxane-polyester copolymer, (3) a silane wherein one of the groups attached to silicon is an epoxy-substituted organic group, at least two of the remaining valencies of the silicon atom being satisfied by alkoxy or alkoxyalkoxy groups, and (4) a titanium chelate. The presence of (3) and (4) improves the rate of cure of the siloxane-polyester, and the compositions are useful for providing decorative and/or protective coatings on metals, plastics and other substrates.
