COSMO® PU-200.310

THE ALL-ROUND SPECIALIST

2-Part PUR Adhesive for Aluminium Corner Joint Bonding

COSMO® PU-200.310 (COSMOFEN DUO.20) is a two-component polyurethane reaction adhesive developed for structural, force-locking bonding applications. It is particularly suitable for bonding corner joints in aluminium window and door manufacturing using both classic and injection bonding methods.

The solvent-free, thixotropic formulation provides a tough-hard adhesive joint with good weather resistance. With a processing time of approximately 10 minutes at +20 °C, functional strength after approximately 1.5 hours and a tensile shear strength of approximately 18 N/mm² on aluminium, COSMO® PU-200.310 is suitable for demanding bonding applications.

The adhesive can be easily processed from a tandem cartridge using a static mixer and is also suitable for bonding different material combinations, including aluminium, HPL and GRP. After reaching its final strength, the adhesive can also be subjected to subsequent powder coating.
