Abstract
The present invention relates to compositions of catalysts to be used in low temperature (<80° C.) moisture curable, two package pigmented coatings as alternative to tin salts. The catalysts based on low toxic hydroxylamines alone or in combination with an organic acid offer low color and high efficiency coatings.
Claims11
A one-component solvent borne curable coating composition comprising:
- (A) an organic polymer having silicon-containing group(s) which can be crosslinked by the formation of a siloxane bond;
- and
- (B) a sterically hindered primary hydroxylamine of
- or
- (C) a sterically hindered primary hydroxylamine of structure 1 combined with an organic acid.
