Safe and Easy Insulation Attachment with an Extended Open Time
3M™ Polystyrene Insulation Adhesive 78 is designed to be a high-solids, high-coverage formula designed for bonding many types of insulation. A lace spray pattern optimized for foam bonding helps bond expanded polystyrene foams (EPS) to themselves and other surfaces, including concrete. This spray is engineered so it won’t dissolve or degrade foam when used according to 3M instructions. With a bonding range of one to 60 minutes, it provides extended open time to let you position parts.
Recommended Applications
- Foundation insulation
- Polystyrene block assembly
- Attaching foam to wood and other substrates
- Proven excellent for roofing and landscaping
- Styrofoam cores for composites
Your Polystyrene Adhesive
3M™ Polystyrene Insulation Adhesive 78 is capable of bonding polystyrene foam onto a wide array of materials, including paper, cardboard, plastic, metal, wood and much more. This spray adhesive has been proven to work well for projects both large and small.
Cylinder Spray Delivery
3M™ Polystyrene Insulation Adhesive 78 can be used with our 3M Cylinder Spray Adhesive system. Each cylinder is self-contained, pressurized and ready for immediate use. Available in a variety of sizes, they’re portable and require minimal equipment investment and maintenance. Our cylinders help increase your productivity with fast application and no time-consuming equipment setup. The applicator and hose connect quickly and allow you to start spraying immediately. The wide, uniform spray is the optimal pattern to deliver effective and economic use of the adhesive. It also minimizes any pooling for even drying. 3M has a complete line of innovative sprayable adhesives that support a wide range of industrial applications, from aerospace to woodworking.
