Desford 4142 is a shelf stable, one component (pre-catalyzed) crosslinking polyvinyl acetate emulsion adhesive. It is designed for cold press applications including finger jointing, but can also be used for radio frequency and hot press gluing. With its very fast setting rate, viscosity stability and high percent solids, Desford 4142 can also be used for a variety of assembly gluing applications. It develops a DIN EN 204 D3 water-resistant bond with a clear glue line.
Six to eight percent is the recommended moisture content of the gluing stock. High moisture content will slow down glue line cure and cause weaker than normal adhesive bonds. Additionally, panel shrinkage may occur resulting in stress cracks or end delamination.
