View of a liquid PU application

Liquid PU – Reliability for the building industry

Polyurethane is an advanced thermoset polymeric composition with unique versatility. The adhesives are available in one-component or two-component systems, bond well to a large variety of materials and are frequently used for load bearing timber constructions as well as panel and sandwich elements. One-component PUR adhesives are applied in areas where ease of use, reliability and durability are required. Two-component systems are perfect for joints that are exposed to dynamic loads like vibrations or heavy impacts.
