COSMOPUR K1

THE SPEED & GAP-FILLING SPECIALIST

Fast 1-Part PUR Assembly Adhesive for Window, Door and Wood Bonding

COSMOPUR K1 (COSMO® PU-100.110) is a fast-reacting, one-component, moisture-curing polyurethane assembly adhesive for bonding applications in window and door construction, woodworking and industry. It is particularly suitable for wood-to-wood bonding and for joining various construction materials after appropriate surface preparation.

The solvent-free, thixotropic formulation stays in place without dripping and forms a tough-elastic adhesive joint. The adhesive expands (foams) during curing, providing joint-filling properties. Its particularly fast reaction and very short pressing times support efficient assembly processes.

COSMOPUR K1 reaches functional strength after approximately 15 minutes at +20 °C, depending on the application. For wood-to-wood bonding, it achieves durability class D4 according to DIN EN 204 and a heat bonding strength of approximately 7.6 N/mm² according to DIN EN 14257 (WATT 91).
