The 3M 7100043839 is a double coated tape in the Venture Tape 3693FLE series, built for trade and construction applications that demand reliable adhesion in low-temperature environments and fire-sensitive installations. The tape uses a thin, transparent film carrier coated on both sides with an aggressive cold weather acrylic pressure-sensitive adhesive (PSA). A finger lift edge is included for clean, controlled application. The tape ships in a 600-yard roll format and carries a UL 723 listing with a 0/0 flame and smoke rating, making it suitable for use where fire code compliance is required.
This double coated tape is intended for HVAC, insulation, and construction applications where fire resistance and low-temperature performance are essential. The cold weather acrylic PSA maintains adhesion in conditions that cause standard adhesives to fail. The finger lift edge speeds up production work by eliminating the need for picks or tools to start each strip. Installers working with duct insulation, vapor barriers, and related building materials will find this format appropriate for high-volume, code-sensitive environments.
Designed as a double coated tape for HVAC insulation, vapor barrier, and general construction bonding applications where UL 723 fire resistance and cold weather adhesion are required.
This tape is typically applied by HVAC technicians, insulation contractors, and general construction trades. Surfaces should be clean, dry, and free of dust or oil before application to ensure full PSA contact. Apply firm pressure along the full length of the tape to activate the adhesive bond. Follow applicable local building and fire codes when using this product in rated assemblies.
