3M 7000123893 Glass Cloth Tape 1.5x36yd 7.0 Mil White

Product Description

The 3M 7000123893 is a general purpose glass cloth tape with a silicone adhesive and a woven glass cloth backing. Sold as a single roll measuring 1.5 inches wide by 36 yards long at 7.0 mil total thickness, this tape is designed for applications that demand high-temperature resistance, strong adhesion, and an abrasion-resistant backing. The silicone adhesive system performs reliably under elevated heat conditions where standard acrylic or rubber-based tapes would fail. A liner is included on the roll for clean handling and controlled dispensing. HVAC technicians, electricians, and industrial maintenance professionals use this tape for insulation holding, wrapping, and masking tasks in high-heat environments.

This glass cloth tape is suited for residential and commercial applications where elevated temperatures or mechanical abrasion are concerns. Typical uses include wrapping ductwork insulation, securing thermal blankets, bundling wire harnesses in engine or HVAC compartments, and masking during high-temperature powder coat or curing processes. The woven glass cloth backing provides tensile strength that holds up under stress and movement in installed assemblies.

Installation Notes

This tape is applied by hand or with a tape dispenser and requires no special tools for most applications. Ensure the substrate surface is clean, dry, and free of oils or dust before applying for maximum adhesion. When used in HVAC or electrical enclosures, follow applicable NEC or local code requirements for tape materials in contact with wiring or insulation. Do not exceed the temperature rating of the tape or the underlying substrate material.
