Abstract:

A chinawood oil-phenolic resin condensate particularly useful in high solids content solution coatings is produced by heat reacting: (1) an o-cresol-formaldehyde condensate containing about 1 to about 2 mols of formaldehyde per mol of o-cresol; with (2) from about 80% to about 95% of its weight of chinawood oil; and (3) from 2% to 10% of the total weight of an alkyd resin which is a condensate of a polyethylenically unsaturated monocarboxylic fatty acid containing from 16-22 carbon atoms with about 0. 5 mol per mol of said acid of an aliphatic glycol having a molecular weight of less than about 200.

Abstract:

A method of forming an aqueous emulsion laminating adhesive having an extended pot life is disclosed in which monoethylenically unsaturated monomers are polymerized to form a copolymer having a glass transition temperature in the range of about -10. degree. C. to about -50. degree. C. The polymerization is carried out in aqueous emulsion in the presence of emulsified epoxy resin in an amount of from about 2% to about 60%, based on the weight of the monomers which are copolymerized. An aqueous emulsion of amine-functional resin is then mixed into aqueous emulsion containing copolymer and epoxy resin formed by the aqueous emulsion copolymerization to provide a weight ratio of amino hydrogen atoms to oxirane groups of from about 0. 1 to about 1.
