Adhesive Bonding Technology

2K polyurethane adhesive │ Fast repair and bonding │ tixothropic.

PUR adhesive is usually used for plastics, and the very low material price is particularly impressive. Silanized PUR adhesives are also suitable for metal or hybrid bonding. In some cases, a primer or adhesion promoter is used on the glass side in hybrid bonding, for example glass on varnish. A dry environment is crucial for processing, as if the moisture is exposed for too long, the MDI, i.e. the hardener, reacts with water to form CO2 (foaming). Hard PUR adhesives are available, but also elastic adhesives with up to 600% elongation at break. In terms of reaction speed, formulations with a few minutes gelling time up to 90 minutes are available. Depending on the application, the cold flexibility of up to -60°C is used, but this depends on the glass conversion temperature of the PUR adhesive used. UV-resistant PUR adhesives are cured with HDI.
