3M 7100009843 Venting Tape Pink 1 Inch X 36 Yards

Product Description

The 3M 7100009843 is a pink non-woven venting tape designed for applications that require controlled outgassing during foam insulation processes. The tape features a 4.0 mil air-permeable non-woven backing coated with a strip-applied acrylic adhesive. The strip coating leaves uncoated lanes across the adhesive surface, which increases permeability in those zones and helps reduce foaming voids during cure. Licensed insulators, foam applicators, and specialty contractors install this tape where foam confinement and outgassing management are both required in the same assembly.

This tape is used in venting applications where foam insulation must be confined but gases generated during curing need a controlled escape path. Typical scenarios include bonding over foam cavity openings or sealing assemblies where outgassing pressure would otherwise cause adhesive failure or void formation. The pink color aids visual identification during installation and inspection. It is sold by the roll and suits both production line and field service use.

Key Features

• Air-permeable non-woven backing allows outgassing while maintaining confinement of foam insulation
• Strip-coated acrylic adhesive creates higher-permeability uncoated lanes to minimize foaming voids
• 4.0 mil total tape thickness for flexible, conformable handling in tight assemblies
• Pink color provides easy visual identification during installation and quality inspection
• 1 inch width by 36 yard length per roll for consistent coverage

Compatibility

Designed for venting applications requiring high outgassing rates, particularly in assemblies involving foam insulation confinement. No specific equipment or model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

This tape is typically applied by insulation contractors or assembly technicians familiar with foam cure requirements. Surfaces should be clean, dry, and free of oils or dust before application to ensure proper adhesion. Apply consistent pressure along the full length of the tape to achieve uniform contact across both coated and uncoated adhesive zones. Do not substitute this air-permeable tape with a solid-backed tape where outgassing is required, as doing so may cause voids or delamination.
