DISPERSE AQUEOUS ADHESIVE, PROCESS OF ITS MANUFACTURE AND USE

摘要

The invention concerns an aqueous dispersion adhesive based on polyvinylacetate and an addition of between 0.1 and 2.0 wt % pyrogenic silicic acid, the dispersion containing less than 5 wt % high-boiling solvents. The polyvinylacetate dispersions are preferably dispersions which produce watertight adhesion pursuant to European standard DIN EN 204. The dispersion adhesives according to the invention are characterized not only by a thixotropic creamy consistency but also by a long open time, rapid setting behaviour, and high resistance to heat. These adhesives are suitable in particular for bonding wood and wooden materials.
