    Abstract: A cross-linkable polymer composition containing a crosslinkable polymer having at least one hydrolysable silane group and at least one lactone or anhydride silanol condensation catalyst for example, lactide and 2-dodecen-1-yl succinic anhydride. The catalyst is not conducive to causing premature cross-linking. The composition provides a cross-linked polymer having good anti-scorch properties. Compositions containing lactones as the silanol condensation catalyst also provide crosslinked polymers having improved adhesion properties.

    Abstract: A curable resin used as a water-based paint, comprise: (A) water-based prod. obtd. by dispersing or dissolving in water a tert. aminovinyl polymer (I) that has been partially or fully neutralised with an acidic cpd.; and (B) cpd. contg. both epoxy and hydrolysable silyl functional gps. Also claimed are similar water-based paints to the above contg.: (1) water-based prod. (C) in place of (A), obtd. from a vinyl polymer (II) contg. tert. amine and acid functional gps., to which sufficient acid is added to give a min. mol. ratio of tert. amino gps. to acid gps. in (II) of 0.1; (2) water-based prod. (D) in place of (A), obtd. from (II), to which sufficient base is added instead of the acidic cpd. to give a min. mol. ratio of basic functional gps. to acid gps. of 0.1; (3) water-based prod. (E) in place of (A), obtd. from an acidic vinyl polymer (III) partially or fully neutralised with a base; (4) (A) or (C) or (D) or (E), (B) and a cpd. (F) contg. a hydrolysable silyl and/or silanol functional gp. which is different to (B); (5) (A) or (C) or (D) or (E), (B) and a curing catalyst (G); and (6) (A) or (C) or (D) or (E), (B), (F) and (G).

    Abstract: A one-package resinous coating composition, especially for automobile finishes (A) a resin having a siloxy group, and (B) a catalyst for dissociating the siloxy group. Resinous mixture (A) contains one or more of the following (A-1) through (A-4). (A-1) a mixture of (a) a resin that contains at least one siloxy group and one alkoxysilyl group respectively in the one molecule, and (b) a resin that contains at least one isocyanate group and one alkoxysilyl group respectively in the one molecule; (A-2) a mixture of (a) a resin that contains at least one siloxy group and one alkoxysilyl group respectively in the one molecule, and (c) a compound or a resin that contains at least two isocyanate groups in the one molecule; (A-3) a mixture of (b) a resin that contains at least one isocyanate group and one alkoxysilyl group respectively in the one molecule, and (d) a compound or a resin that contains at least two siloxy groups in the one molecule; and (A-4) (e) a resin that contains at least one siloxy group, one isocyanate group and one alkoxysilyl group respectively in the one molecule.

    Abstract: In one aspect, this invention is a primer comprising a solution of: (a) a polyester resin of a carboxylic acid and a glycol; (b) a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; and (c) a silane-containing moiety; in a solvent mixture comprising: (i) a high boiling polar solvent; (ii) an oxygenated solvent; and (iii) an aromatic solvent; wherein the weight ratio of (a):(b) is in the range of from about 0.25:1.0 to 2.0:1.0. In a second aspect, this invention is a primer comprising a solution of: (a) 5-50% of a polyester resin of a carboxylic acid and a glycol; (b) 5-50% of a polymethylene poly(phenyl isocyanate), diphenylmethane diisocyanate, or mixture thereof; (c) 0.1-50% of a silane-containing moiety; (d) 0.1-50% of a high boiling polar solvent; (e) 10-70% of an oxygenated solvent; and (f) 1-50% of an aromatic solvent. It has been discovered that the primer of the invention advantageously provides improved adhesion characteristics of metal-to-glass bonding when used to prime acid resistant paint-coated metal substrates before applying a urethane adhesive, particularly when used with a "fast cure" adhesive comprising an isocyanate-functional prepolymer and dimorpholinediethyl ether.
