COSMO® PU-100.220

Fast 1-Part PUR Adhesive for Aluminium Corner Connector Bonding

COSMO® PU-100.220 (COSMOPUR 1753) is a fast-reacting, one-component, moisture-curing polyurethane assembly adhesive. It is particularly suitable for bonding corner connectors in aluminium window and door manufacturing and for numerous assembly applications in construction and industry.

Thanks to its particularly fast reaction and very short pressing times, it supports efficient assembly processes. At +20 °C, functional strength is reached after approximately 18 minutes, depending on the application. The solvent-free, thixotropic formulation remains in place without dripping and forms a tough-elastic adhesive joint.

The adhesive expands (foams) during curing, offering joint-filling properties. It provides good bonding strength and weather resistance and is compatible with natural stone. After complete curing, bonded components can be overcoated with suitable paint systems or subsequently powder-coated under the conditions specified in the technical data sheet.
