Product Description

The 3M 7000000803 is a high-performance neoprene contact adhesive sold under the Scotch-Weld 1357 line. It bonds on contact after both surfaces are coated and allowed to dry, making it well suited for high-stress bonding applications where a strong, flexible bond is required. The adhesive is gray-green in color and is packaged in a 1-gallon container. It is used across a range of trade and industrial settings, including HVAC duct fabrication, insulation installation, and general sheet material bonding. Licensed tradespeople and industrial maintenance crews are the primary installers.

This adhesive is commonly applied in commercial and residential construction and mechanical contracting work. It performs on a wide range of substrates including rubber, leather, fabric, metal, wood, and rigid plastics. Its neoprene base provides flexibility and resistance to heat and moisture after cure, making it a reliable choice for insulation and gasket bonding in mechanical systems. The 1-gallon size is suited for jobsite or shop use where larger quantities are needed.
