Adhesive composition

Abstract

Abstract PURPOSE:To obtain an adhesive composition, as a plywood adhesive, improved in adhesion to resinous wood and durability and shortened in a hot-pressing time by mixing a formalin condensation resin with an acidified aminoethylated vinyl interpolymer. CONSTITUTION:An adhesive composition is formed by mixing 100pts.wt. (in terms of solid matter) formalin condensation resin (A) (desirably, a condensate of formaldehyde with an amino compound such as urea in a molar ratio of 1.5-2.8, having a solid content of 45-75%) with 0.05-50pts.wt., desirably, 0.5-20pts. wt. acidified aminoethylated interpolymer [a salt of an aminoethylated interpolymer of the formula (wherein R and R<1> are the same or different and are each H or a 1-4 C alkyl, and n is 1.0-2.5 on the average with formic acid or acetic acid].
