3M 7010333554 Glass Cloth Tape White 5in X 60yd 8.3 Mil

Product Description

The 3M 7010333554 is a white, thermosetable glass cloth tape rated at 8.3 mil total thickness. It combines a high-tensile-strength woven glass cloth backing with a thermosetable rubber-resin adhesive that flows under heat and pressure to create a firm, lasting bond. The result is a tape that conforms to irregular or rough surfaces while maintaining strong adhesion. Each roll measures 5 inches wide by 60 yards long. This tape is suited for industrial and commercial applications where standard tapes fail due to surface texture, low substrate strength, or temperature exposure. Installation is typically handled by HVAC technicians, insulation contractors, and industrial maintenance professionals.

This tape is designed for splicing and bonding applications involving materials with rough surfaces or low internal strength. Common use cases include splicing roofing felt, textiles, and similar flexible substrates. The thermosetable adhesive provides high holding power that activates with heat, making it well suited for applications where a permanent, high-strength bond is required. It performs in environments where conformability and backing integrity are critical to the finished installation.

Key Features

• 8.3 mil total thickness for a durable, conformable profile
• Thermosetable rubber-resin adhesive flows under heat for high holding power
• Woven glass cloth backing offers high tensile strength and temperature resistance
• Conforms to rough, irregular, or low-strength surfaces
• White finish; roll format for straightforward field application
• 5 inches wide by 60 yards per roll for coverage on larger splicing jobs

Compatibility

Designed for splicing and bonding roofing felt, textiles, and similar rough-surface or low-internal-strength materials in industrial and commercial installation settings.

Installation Notes

Apply to clean, dry surfaces for best adhesion; remove dust, oil, and loose material before taping. Heat activation of the thermosetable adhesive typically requires a heat source appropriate to the substrate — follow the material manufacturer's guidelines for temperature limits. Wear appropriate PPE when working with heat-activated adhesives in enclosed or poorly ventilated spaces. This product is sold by the roll with a minimum order quantity of 8 rolls.
