Safe and Easy Insulation Attachment with an Extended Open Time
3Mâ„¢ 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
