COSMOFEN DUO

THE PROVEN SPECIALIST

2-Part PUR Corner Angle Adhesive

COSMOFEN DUO (COSMO® PU-200.280) 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 resistance to weathering. With a processing time of approximately 30 minutes at +20 °C and a tensile shear strength of approximately 18 N/mm² on aluminium, COSMOFEN DUO is suitable for demanding bonding applications.

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