3M 7000123431 Glass Cloth Tape 0.5in X 60yd 8.3 Mil

Product Description

The 3M 7000123431 is a white, thermosetable glass cloth tape designed for demanding bonding and splicing applications that require high adhesion and a durable, conformable backing. The tape measures 0.5 inches wide by 60 yards long and carries an 8.3 mil total thickness. Its rubber-resin adhesive undergoes a thermoset cure, delivering strong holding power and excellent flow characteristics that allow it to bond securely to rough, irregular, or low-strength surfaces. The high-tensile-strength glass cloth backing provides reliable temperature resistance, making this tape suitable for industrial and trade applications where standard cloth tapes fall short.

This tape is used in applications requiring a strong, heat-resistant bond on difficult substrates. It performs well for splicing roofing felt, textiles, and similar materials with rough surfaces or low internal strength. Typical install scenarios include manufacturing, insulation work, and field splicing where the thermoset adhesive's flow properties are needed to achieve full surface contact. Trade professionals in HVAC, roofing, and general industrial service find this tape useful when conformability and temperature resistance are critical requirements.

Key Features

• Thermosetable rubber-resin adhesive provides high holding power and bonds well to rough or low-strength surfaces
• 8.3 mil total thickness offers durability without excessive bulk
• High-tensile-strength glass cloth backing resists tearing during application and in service
• Temperature-resistant backing suitable for elevated-heat environments
• Conformable construction allows the tape to follow irregular or uneven surface contours
• White color assists in visual identification in multi-tape applications

Compatibility

Designed as an OEM-style splicing and bonding tape for use on roofing felt, textiles, and other materials with rough surfaces or low internal strength where high adhesion and temperature resistance are required.

Installation Notes

Surface preparation is critical before applying this tape — ensure the substrate is clean and free of loose debris for maximum adhesion. Apply firm, even pressure across the full tape width to allow the adhesive to flow and make full contact with the surface. Follow the thermoset cure instructions appropriate to the application environment. Handle in accordance with applicable worksite safety requirements for adhesive tapes used in roofing or industrial settings.
