3M Polystyrene Insulation 78 Spray Adhesive

3M Polystyrene Insulation 78 spray adhesives bond expanded and extruded polystyrene foam to itself, wood, metal, and other surfaces, and are formulated to avoid the foam damage some solvent sprays cause. This page carries 78 in clear and inverted aerosols, plus 78 ET and high-temperature 78 HT in large cylinders. See Aluminum Tapes for sealing insulation seams.
