3M 7100138480 Holdfast 70 Cylinder Spray Adhesive

Product Description

The 3M 7100138480 is the HoldFast 70 Cylinder Spray Adhesive, an industrial-grade contact adhesive packaged in a pre-pressurized, maintenance-free canister. It delivers a wide-web spray pattern that distributes adhesive evenly across large surface areas, promoting fast tack and quick permanent bonds. Designed for demanding applications across construction, HVAC, specialty vehicle fabrication, manufactured housing, and RV assembly, it bonds a broad range of substrates including polystyrene, drainboard, FRP panels, rigid insulation, flexible foams, and fabrics. The clear adhesive minimizes visible residue at bond lines, making it well suited for finish-sensitive assemblies.

This adhesive sees regular use in HVAC duct liner and insulation installation, where fast tack and compatibility with polystyrene and foam substrates are critical. It is also used in manufactured housing and RV panel assembly, specialty vehicle interior fabrication, and general construction bonding tasks. The pre-pressurized cylinder eliminates the need for spray equipment or compressor setups, allowing technicians to apply adhesive directly on the job site or in the shop without additional tooling.

• Pre-pressurized canister — no spray gun, compressor, or maintenance required
• Clear adhesive minimizes visible residue at bond lines
• Suited for HVAC, construction, RV, specialty vehicle, and manufactured housing applications

Compatibility

Designed for bonding polystyrene, drainboard, FRP panels, rigid and flexible insulation, foams, and fabrics in construction, HVAC, specialty vehicle, RV, and manufactured housing applications.

Installation Notes

Application is typically performed by HVAC technicians, insulation contractors, and fabricators working with foam and panel substrates. Ensure surfaces are clean, dry, and free of dust or oils before applying. Use in well-ventilated areas and follow applicable safety data sheet guidelines for respiratory and skin protection. Allow adequate open time before joining substrates to achieve the rated bond strength.
