Abstract: This invention relates to high solids, large particle size latexes useful as, and in, corrosion resistant coating compositions.

Abstract: A method of bonding a flexible substrate; e.g., vinyl, cloth, paper, etc., to a rigid wood substrate. The method comprises consolidating the two substrates through the medium of a curable adhesive composition consisting essentially of an aqueous emulsion of a butyl acrylate-methyl methacrylate-2-hydroxyethyl acrylate terpolymer adjusted to pH 9 to pH 10 with 2-amino-2-methyl-propanol, polypropylene glycol, an acrylamide-acrylic acid copolymer thickener, containing a dispersed polyisocyanate hardening agent. Decorative vinyl/wood laminates for use in mobile home construction can be advantageously prepared in this manner.

Abstract: Disclosed is an improved aqueous latex adhesive composition of the type having an aqueous latex in admixture with a water dispersible multi-isocyanate cross-linking agent and a thickener. The improvement for a room temperature curable adhesive composition having improved water resistance comprises the curable ingredients consisting essentially of an aqueous hydroxyl functional latex which contains hydroxyl groups as its only isocyanate reactive functionality and the multi-isocyanate cross-linking agent. The cross-linking agent is a water dispersible or water dispersed multi-isocyanate and preferably is a multi-isocyanate which has undergone partial reaction of some of its isocyanate groups with a hydrophobic monohydroxy alcohol. Desirably, fillers incorporated into the adhesive composition are formed into a filler grind prior to incorporation into the adhesive composition. The adhesive composition is especially useful as a structural adhesive in structural lamination manufacture.
