We stock a wide range of polyurethane adhesives from specialist brands and manufacturers. These adhesives consist of isocyanate containing pre-polymers that are dissolved in a solvent carrier. Reaction with moisture occurs as the solvent evaporates. Unless the curing takes place inside of the pressure device, bubbles may form during curing. Polyurethanes are used extensively in woodworking, wood to metal and can be used for glueing metals, ceramics, stone, glass and most plastics.
