Safe and Easy Insulation Attachment with an Extended Open Time
3M™ Polystyrene Insulation 78 ET Cylinder Spray Adhesive 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.
