COSMOPUR 818

THE VERSATILE 1C SPECIALIST

1-Part PUR Adhesive for Aluminium Corner Connector Bonding

COSMOPUR 818 (COSMO® PU-180.120) is a one-component, moisture-curing polyurethane adhesive designed for bonding corner connectors in aluminium window and door manufacturing. It is also suitable for high-strength bonding of mitre-cut surfaces of PUR window and door profiles and various assembly bonding applications.

The solvent-free, thixotropic formulation provides a tough-elastic adhesive joint and does not drip during application. The adhesive expands (foams) during curing, offering joint-filling properties and good bonding strength. Thin adhesive layers become transparent after curing, and the formulation is compatible with natural stone.

COSMOPUR 818 reaches functional strength after approximately 300 minutes at +20 °C for corner angle bonding and final strength after approximately 7 days at +20 °C and 50% relative humidity. After complete curing, the adhesive can also be subjected to subsequent powder coating.
