COSMOPUR 828C one-component PUR adhesive for aluminium window and door corner connector bonding

COSMOPUR 828C

THE TOUGH-HARD SPECIALIST

1-Part PUR Adhesive for Aluminium Corner Connector Bonding

COSMOPUR 828C (COSMO® PU-100.210) is a one-component, moisture-curing polyurethane construction adhesive designed for bonding corner connectors in aluminium window and door manufacturing. It is also suitable for a wide range of assembly bonding applications in construction and industry.

The solvent-free, thixotropic formulation stays in place without dripping and forms a tough-hard adhesive joint. The adhesive expands (foams) during curing, providing joint-filling properties and good bonding strength. It also offers good weather resistance and is compatible with natural stone.

COSMOPUR 828C reaches functional strength after approximately 75 minutes at +20 °C, depending on the application. After complete curing, the adhesive can be overcoated with many paint systems, subsequently powder-coated under the specified conditions or sanded.
