Date Nov. 28, 1996A composition of a hydroxyl functional polymer, an acetate functional polymer and a carboxyl functional polymer, which are crosslinked by a polyfunctional aziridine. Preferably, PVOH, polyvinylacetate and a carboxylated styrene/butadiene are used as the polymers. The aziridine can be held separate from the polymers prior to crosslinking. The composition is useful as a wood adhesive or coating composition.</p> |
