FORTIS PA75 is a very high-quality heat-resistant carbon/polyurethane-based contact adhesive for the adhesion of various types of vinyl, rubbers and laminates.
FORTIS PA75 polyurethane contact adhesive is fast drying, has excellent heat resistance and has superior bonding for challenging surfaces such as vinyl, some plastic and metals. FORTIS PA75 can be applied using a brush, roller or spray and is ideal for bonding laminates that may need the application of an adhesive before heat activation. It is best used in the auto-trim, dashboards, seating and marine finish. PA75 is isocyanate free.

For gluing all types of surfaces. FORTIS PA75 may be applied by brush, roller-coater or automatic cementing machine. An even coat of adhesive should be applied to both surfaces and allow to dry for 10-15 minutes. The substrates should be reactivated at a temperature of no less than 55°C and pressed for 60 seconds at 80PSI. Substrates may be pre-coated and stored for a short period of time. For higher temperature resistance we recommend the use of Fortis PA75 Catalyst at between 5-15% by weight.
All surfaces to be bonded must be clean, dry and free of any oils or grease. Smooth or polished surfaces should first be roughed with fine abrasive. If degreasing is necessary, a detergent/water treatment should first be considered. If this is inappropriate, a suitable solvent such as Acetone may be used. It is advisable to check the effects of degreasing solvents on plastics, rubber materials and painted surfaces before carrying out the operations.
PVC: Roughen lightly or wipe with a solvent.
LEATHER: Roughen well, removing all pigment
COATED FABRICS: Roughen synthetic coating or solvent wipe.
RUBBER: Roughen the surface and wipe with acetone.
POLYURETHANE: Roughen the surface and double wipe with acetone. It is recommended that the glue be tested for a suitable bond to the substrate before application
