Features
■ Bonds wide variety of substrates, including most foams, plastics, particle board, light gauge metals.
■ Controlled application with minimal over-spray.
■ One or two surface application.
■ Immediate initial strength.
■ Long bonding range. Product Description 3M™ Spray-Bond Adhesive 6116 is a heat applied, solvent-free, 100% solids, sprayable thermoplastic adhesive. It is a fast, neat alternative to aerosols, contact adhesives and solvent-based adhesives for bonding most foams and many other lightweight materials. 3M spray-bond adhesive 6116 is lower than normal viscosity and is designed for use on fabrics, as the long open time allows flexibility in production. (1)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 seconds of firm pressure. After standing for 24 hours, 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 seconds of firm pressure. After 24 hours, bonds were pulled apart by hand. The criterion for open time is 100% foam tear.
