3M 7100138815 Foam Insulation 78 Et Spray Adhesive

Product Description

The 3M 7100138815 is a pre-pressurized cylinder spray adhesive formulated specifically for bonding polystyrene foam insulation in industrial and trade applications. This tacky, industrial-grade adhesive features a long open time, giving installers sufficient working time to reposition materials before the bond sets. The controlled, uniform spray pattern reduces waste and delivers consistent coverage across large surface areas. At 41.47 pounds per unit, the large cylinder format is suited for high-volume jobs where frequent canister changes are not practical. It ships ready to use with no mixing, priming, or pressurization required.

This adhesive is used in HVAC insulation work, commercial and residential construction, and other polystyrene foam fabrication applications. It is well suited for duct insulation lining, board stock lamination, and foam panel assembly. The pre-pressurized delivery system makes it a practical choice for field technicians and shop fabricators who need a maintenance-free, consistent application tool. Its clear finish leaves bonded surfaces with a clean appearance where aesthetics matter.

Key Features

• Long open time allows repositioning of foam materials before final bond sets
• Controlled, uniform spray pattern for consistent adhesive coverage
• Pre-pressurized canister requires no pump, mixing, or external pressurization equipment
• Industrial-grade tack rated for polystyrene foam bonding in HVAC and construction
• Clear adhesive finish suitable for visible or finished surfaces
• Large cylinder format reduces changeover frequency on high-volume jobs

Compatibility

Designed for bonding polystyrene foam insulation materials in HVAC duct lining, construction panel assembly, and other polystyrene fabrication applications where a spray-applied adhesive is required.

Installation Notes

This product is typically applied by HVAC technicians, insulation contractors, and sheet metal fabricators working with foam board or duct liner materials. Before application, ensure surfaces are clean, dry, and free of dust or oils that could inhibit adhesion. Work in a well-ventilated area and follow applicable safety data sheet guidance for respiratory and skin protection. Do not apply near open flame or ignition sources, as the propellant is pressurized.
