Brookfield Thermocel Viscometer in Centipoise using a #27 Spindle @ 20 RPM 2. Bonds were made by spraying adhesives onto 3/4 in. thick, 2-lb. density polyester urethane foam. PVC coupons wiped with isopropyl alcohol and then bonded to foam using 5 sec of firm pressure. After standing for 24 hrs, bonds were pulled apart by hand. The criterion for open time is 100% foam tear. 3. Two pieces of 3/4 in. thick, 2-lb. density polyester urethane foam were sprayed and bonded using 5 sec of firm pressure. After 24 hrs, bonds were pulled apart by hand. The criterion for open time is 100% foam tear. Features ■ Sprayable thermoplastic adhesive. ■ Solvent-free, 100% solids. ■ One or two surface application. ■ Long bonding range. ■ Immediate initial strength ■ Excellent adhesion to polypropylene ■ Bonds wide variety of substrates, including most foams, plastics, particle board, light gauge metals. ■ Controlled application with minimal overspray.
