Description

Adding isocyanates gives the adhesive bonds much higher heat, solvent and water resistance compared to the adhesive without crosslinker added.

The adhesion to all substrates is dramatically improved, especially in the case of Bostik 2402 adhesive to rubber and metal. In the case of Bostik’s Polyurethane adhesives such as Unigrip 999 and Ultragrip 777 there is a much-increased water and heat resistance.

Some adhesives such as Bostik’s 1659 & 2402 contact adhesives must use crosslinking agents; they are part of the adhesive system.

Nitrile adhesives such as Clear Bond also benefit greatly from the addition of isocyanates.

The heat resistance and adhesion is boosted.
