摘要： Polyvinyl acetate emulsion based adhesives can be made effective for bonding melamine formaldehyde resin treated decorative solid color and print paper to particle board. This polyvinyl acetate emulsion based adhesive is formulated with tackified polyvinyl alcohol, starch, a tackifier and a coupling agent. Stress cracking is substantially eliminated. Additionally, wrinkling and edge and corner peel resulting during the movement of sheets of melamine resin treated paper on the top and bottom surfaces of sheets of particle board through a heating and pressing zone is substantially eliminated.
