<p>Siloxane-polyester compositions comprising (1) a siloxane-polyester copolymer resin (2) a silane wherein one of the groups attached to silicon is an organic group containing at least one amino group, the remaining valencies of the silicon being satisfied by alkoxy, alkoxyalkoxy, methyl or phenyl groups there being present at least two alkoxy or alkoxyalkoxy groups, (3) a solvent for the siloxane-polyester copolymer and (4) a titanium chelate. The presence of (2) and (4) improves the rate of cure of the siloxane-polyester, and the compositions are useful for providing decorative and protective coatings on metals, plastics and other substrates.</p> |
