COSMOPUR 819

THE GAP-FILLING SPECIALIST

1-Part PUR Assembly Adhesive

COSMOPUR 819 (COSMO® PU-100.130) is a one-component, moisture-curing polyurethane 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-elastic adhesive joint. During curing, the adhesive expands (foams), providing joint-filling properties. It offers good adhesion to various materials after appropriate surface preparation and is compatible with natural stone.

COSMOPUR 819 features fast and homogeneous curing, reaching functional strength after approximately 20 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.
