3M 7100138682 Foam Insulation Spray Adhesive Clear

Product Description

The 3M 7100138682 is a tacky, industrial-grade spray adhesive formulated specifically for bonding polystyrene foam insulation. It features a long open time that gives installers working time to position and reposition materials before the bond sets. The adhesive delivers a controlled, uniform spray pattern from a pre-pressurized cylinder, making application consistent across large surface areas. The maintenance-free, self-contained delivery system requires no external pump or mixing equipment. This product is well suited for HVAC insulation work, commercial construction, and other trades that regularly handle polystyrene foam substrates.

This adhesive is used in residential and commercial HVAC applications where polystyrene foam board or pipe insulation must be bonded to ductwork, framing, or building envelope surfaces. It is also applicable in general construction and industrial settings that require a reliable, fast-application bond on foam materials. The cylinder format makes it practical for both shop-bench work and field installation where portability and speed matter.

Key Features

• Long open time allows repositioning of foam pieces before final bond sets
• Controlled, uniform spray pattern reduces adhesive waste and overspray
• Pre-pressurized cylinder requires no external air supply or maintenance
• Industrial-grade tack suitable for demanding HVAC and construction environments
• Formulated specifically for polystyrene foam substrates
• Clear adhesive leaves no visible residue on finished assemblies

Compatibility

Designed for use with polystyrene foam insulation materials in HVAC, construction, and other polystyrene-related applications.

Installation Notes

Application is typically performed by HVAC technicians, insulation contractors, or construction tradespeople. Ensure the work area is adequately ventilated before spraying, as aerosol adhesives produce airborne particulates and vapors. Keep the cylinder away from open flames, heat sources, and electrical ignition sources during use and storage. Follow all local building and mechanical codes regarding adhesive use in air-handling and plenum spaces.
