3M Scotch-Weld 1357 Gray-Green Neoprene Contact Adhesive – 5 Gallon for Production-Scale Bonding
3M Scotch-Weld 1357 is a high-performance, gray-green neoprene-based contact adhesive available in a 5 gallon pail format for production-scale flexible bonding operations in aerospace, automotive, and industrial manufacturing. It provides strong, durable flexible bonds across a broad range of substrate combinations including rubber-to-metal, fabric-to-composite, foam-to-plastic, and similar mixed-material interfaces encountered in aircraft interior assembly, upholstery production, and industrial fabrication.
The 5 gallon pail is the most economical format for high-volume production operations where brush, roller, or spray application of contact adhesive to large bonding areas is performed daily. The bulk pail significantly reduces the per-unit adhesive cost compared to smaller container formats and ensures continuous material availability throughout extended production runs without frequent container changes.
3M Scotch-Weld 1357 delivers the superior adhesion, flexibility, and durability expected of the Scotch-Weld brand, with the high-performance neoprene formula providing particularly strong adhesion to rubber and fabric substrates that are critical to aerospace interior bonding operations.

Technical Information
3M Scotch-Weld 1357 uses a neoprene (polychloroprene) rubber polymer in an organic solvent system to deliver high-tack, high-strength flexible contact adhesive performance. The neoprene polymer provides strong, durable adhesion to vulcanized rubber, fabric, foam, and composite substrates that are difficult to bond with non-rubber-compatible adhesive systems. The gray-green color provides a distinctive visual identifier on bonded assemblies for production quality control.
For spray application from the 5 gallon pail, the adhesive should be transferred to appropriate spray equipment compatible with the adhesive’s solvent system. Spray application enables rapid, uniform coverage of large bonding areas and reduces application time compared to brush or roller methods on large-scale production assembly operations. Spray application requires adequate ventilation and appropriate respiratory protection due to the solvent-based formulation.
Contact bond assembly of large-area joints requires careful alignment of the adhesive-coated surfaces before contact, as the immediate high-strength bond formed on contact makes repositioning of bonded surfaces difficult. Planning and fixturing the assembly sequence before joining large bonded assemblies is important to ensure correct alignment in the final bonded position.
