COSMOPUR 818C

1-Part PUR Adhesive for Aluminium Corner Connector Bonding

COSMOPUR 818C (COSMO® PU-100.310) 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 semi-hard adhesive joint. With a skinning time of approximately 20 minutes under dry test conditions at +20 °C and 50% relative humidity, COSMOPUR 818C offers a useful working-time reference for assembly processes. Actual joining times depend on the application and processing conditions.

The adhesive expands (foams) during curing, providing joint-filling properties and good bonding strength, including at elevated temperatures. Thin adhesive layers are transparent, and the formulation is compatible with natural stone. Functional strength is reached after approximately 75 minutes at +20 °C, depending on the application.
