The 3M 7100037499 is a double coated PET tape designed for high-performance bonding in demanding industrial and construction applications. Featuring an acrylic adhesive on both sides, this tape is mounted on a moisture-stable 74-pound release liner that protects the adhesive from heat and humidity until the moment of application. The liner allows the tape to wet-out properly during bonding, which is critical for achieving a reliable, permanent bond. At 0.59 inches wide, it suits precision bonding tasks where controlled placement is required. Licensed HVAC, mechanical, and general trade installers turn to this tape for structural and assembly bonding where conventional fasteners are impractical.
This tape is engineered for use on difficult-to-bond substrates, including high surface energy plastics, composite materials, cloth, and insulation facings. Its high adhesive coat weight enables permanent adhesion across a wide range of environmental conditions. Applications include laminating, component assembly, and securing insulation facings in both residential and light commercial settings. The tape performs consistently across temperature extremes and resists UV degradation, making it suitable for both indoor and outdoor installations.
Designed for bonding to high surface energy plastics, composite materials, cloth, and insulation facings in demanding industrial and construction assembly applications.
Surface preparation is critical for achieving full bond strength — clean and dry all substrate surfaces before applying the tape. Remove the release liner carefully to avoid contaminating the adhesive. Apply firm, even pressure across the tape length to ensure full wet-out contact. This tape should be applied by experienced trade professionals following applicable safety and material handling guidelines.
