3M 7100104081 Cryogenic Vapor Barrier Foil Tape 2.83 in White

Product Description

The 3M 7100104081 is a multi-layered, self-adhesive cryogenic vapor barrier tape engineered for low-temperature sealing applications. Known as Venture Tape 1555CW/W, it uses a pressure-sensitive cold-weather acrylic adhesive that bonds reliably in temperatures well below freezing. The laminate construction features polyester coating on both sides to eliminate pinhole formation, and the flexible foil backing conforms to irregular and curved surfaces. This tape is primarily installed by insulation contractors and mechanical insulation technicians working on cryogenic pipelines, refrigerated systems, and low-temperature vapor barrier assemblies.

This tape is suited for sealing joints and seams in vapor barriers on cryogenic and low-temperature systems in industrial, commercial, and mechanical insulation applications. The all-weather design means it can be applied and remain effective across a wide range of environmental conditions. It is particularly useful where a zero-permeability vapor seal is required at seams, laps, and terminations in insulation jacketing systems.

Key Features

• Zero permeability construction provides a complete vapor barrier at sealed seams and joints
• Polyester coating on both sides of the laminate prevents pinhole formation
• Cold-weather acrylic adhesive bonds in temperatures well below freezing
• High puncture and tear resistance for durability in demanding environments
• Flexible backing conforms to curved and irregular surfaces
• White foil facing for clean appearance on finished insulation systems

Compatibility

Designed as an OEM-style replacement and standard-use tape for low-temperature vapor barrier joint closure applications in cryogenic and mechanical insulation systems.

Installation Notes

Installation is typically performed by licensed insulation mechanics or mechanical insulation contractors. Ensure the substrate surface is clean, dry, and free of frost or ice before application to achieve full adhesive contact. Apply firm, even pressure across the full width of the tape using a roller or seam roller tool. Follow applicable mechanical insulation standards and local code requirements when sealing vapor barrier systems on cryogenic piping.
