There is a tin-free curable composition having (A) one or more organic polymers having a reactive-silicon-containing group, wherein at least one polymer has a main chain skeleton selected from the group consisting of polyoxyalkylene polymers, saturated hydrocarbon polymers, and (meth)acrylic acid ester polymers; (B) from 0.001 to 20 parts by weight for 100 parts by weight of the organic polymer(s) (A) of a silanol condensation catalyst consisting of one or more metal amidine complexes and one or more amine carboxylate salts, (C) a crosslinker or chain extender chosen from an alkoxysilane, an alkoxysiloxane, an oximosilane, an oximosiloxane, an epoxysilane, an epoxysiloxane, an aminosilane, a carboxysilane, a carboxysiloxane, an alkylamidosilane, an alkylamidosiloxane, an arylamidosilane, an arylamidosiloxane, an alkoxyaminosilane, an alkaryaminosiloxane, an alkoxycarbamatosilane, an alkoxycarbamatosiloxane, and combinations of two or more thereof; and (D) at least one adhesion promoter chosen from a silane or siloxane other than the compounds listed under (C). There is also a cured polymer formed from the tin-free curable composition.

Curable coating compositions of silane functional polymers

Described are coating material compositions comprising an isocyanate group-containing component, a hydroxyl group-containing component, and a zinc (1-methylimidazole)bis(2-ethylhexanoate) complex. Also described is the use of a zinc (1-methylimidazole)bis(2-ethylhexanoate) complex as a catalyst system for the urethane reaction in coating material compositions.

Zinc (1-methylimidazole)bis(2-ethylhexanoate) complex catalyzed coating material composition

Select metal salts of mono and di aromatic sulfonic acids and aliphatic sulfonic acids are effective latent acid catalysts in coating compositions capable of acid catalyzed crosslinking and provide coating compositions with lower cure temperature and quicker cure times than encountered with conventional sulfonic acid catalysts, have excellent storage stability and avoid drawbacks of epoxy and amine blocked sulfonic acid catalysts.

Lower temperature cure coating compositions

The present invention is directed to novel organometallic complexes as catalysts for the reaction of compounds with isocyanate and hydroxyl functional groups to form urethane and/or polyurethane and the process employing such catalysts. More particularly, the present invention is directed to novel complexes of zinc(II) with substituted amidines. These novel catalysts are useful for the production of urethanes and polyurethanes which are important in many industrial applications.

Organometallic compositions and coating compositions

Described herein are metal amidine complexes in combination with a second compound useful as catalysts in a number of polymerization reactions, including polyurethane and epoxy polymerization reactions. Also described herein are various coating compositions and methods of using same for coating substrates using the metal amidine complexes in combination with a second compound.
