GSP AD204-3 is a one-part, reactive polyurethane adhesive that cures at room temperature. The system was developed for bonding porous and non-porous substrates, such as: wood fabric, leather, ABS, concrete and PVC. It has a honey-like consistency and can be easily poured and spread onto bonding surfaces. The foaming effect that occurs during the curing process promotes adhesion by to increasing the surface area of the bond and penetrating the substrate in porous surfaces. Cure rate may be accelerated by misting water onto substrate prior to application.
