3M 7000138489 High Temp Masking Tape 72mm 55m Tan

Product Description

The 3M 7000138489 is a high temperature masking tape designed for paint masking applications where heat resistance is required during spray or bake cycles. Built on a tan crepe paper backing with a rubber adhesive, this tape holds a clean edge under elevated temperatures up to 300 degrees F (149 degrees C). At 7.3 mil thick and 72 mm wide, it delivers a tensile strength of 26 lb/in, giving it enough body to conform to curves and contours without tearing during application or removal. Each roll is 55 meters long. Licensed HVAC techs, auto body professionals, and industrial painters rely on this tape for masking during powder coat prep, oven curing, and high-heat spray environments.

This tape is suited for use in residential and commercial settings where surfaces must be protected during high-heat finishing processes. Typical applications include masking automotive parts before paint bake cycles, protecting fittings and housings during powder coat operations, and shielding surfaces near HVAC or industrial equipment during thermal spray work. The 72 mm width makes it practical for masking wide flanges, ducts, and large panel edges in a single pass.

Key Features

• Maximum operating temperature of 300 degrees F (149 degrees C) for paint bake and curing cycles
• Crepe paper backing conforms to curves and irregular surfaces without tearing
• Rubber adhesive bonds firmly and releases cleanly after heat exposure
• Tensile strength of 26 lb/in resists tearing during hand-tear application
• 72 mm width covers wide masking runs in fewer strips
• 55 m roll length reduces mid-job roll changes on large projects

Compatibility

Designed for general-purpose high temperature paint masking applications where surface temperatures reach up to 300 degrees F, including powder coat, oven cure, and industrial spray finishing processes.

Installation Notes

Apply to clean, dry surfaces free of oil, dust, and loose material for best adhesion and clean edge definition. Press the tape firmly along edges to prevent bleed-through during spray or bake operations. Remove the tape while the surface is still warm, before the adhesive fully cools and sets, to reduce the risk of residue transfer. No special tools are required, but consistent hand pressure along the full tape length is recommended during application.
