Low Cost PVAc / Starch Wood Adhesives - Formulation Guide

The low viscosity of the PVAc water emulsion and its fast setting capability provide an excellent adhesive for wood bonding. The adhesive has good resistance to water and good adhesion to most substrates. This formulation has improved wet tack. It also tends to have thixotropic properties that eliminate stringiness, provide consistency, and control ...
