3M 7010373472 Glass Cloth Tape 3650 White 4in X 60yd 8.3 Mil

Product Description

The 3M 7010373472 is a thermosetable glass cloth tape in the 3M 3650 series, designed for high-adhesion bonding in demanding industrial and trade applications. The tape features an 8.3 mil white glass cloth backing with a blue poly film liner and a thermosetable rubber-resin adhesive system. The combination of high tensile strength, temperature resistance in the backing, and the flow properties of the thermoset adhesive makes this tape well suited for splicing and securing materials with rough surfaces or low internal strength. Each roll measures 4 inches wide by 60 yards long. Installation is handled by HVAC technicians, electricians, and industrial maintenance professionals working with insulation, ducting, and textile assemblies.

This tape is used across a range of applications that demand strong adhesion to difficult substrates. Common use cases include splicing roofing felt, textiles, and other materials with rough or porous surfaces that resist conventional tapes. The 3650 series is a poly-linered version of 3M 365 tape, offering the same adhesive performance with added liner protection during handling and storage. It is suited for both residential and commercial installations where conformability and holding power under thermal stress are required.

Key Features

• 8.3 mil glass cloth backing provides high tensile strength and temperature resistance
• Thermosetable rubber-resin adhesive delivers high holding power and conforms to rough or irregular surfaces
• Poly-linered construction protects adhesive during handling and storage
• White backing with blue film liner for visual identification during installation
• Designed for splicing materials with rough surfaces or low internal strength such as roofing felt and textiles
• 4 inches x 60 yards per roll suits wide-area applications

Compatibility

Designed as an OEM-style replacement and general-purpose glass cloth tape compatible with applications requiring thermosetable adhesive bonding to rough, porous, or low-strength substrates including roofing felt and textile materials.

Installation Notes

This tape is typically installed by HVAC technicians, electricians, and industrial maintenance professionals. Ensure the substrate surface is clean, dry, and free of dust or oils before application to achieve full adhesive contact. Apply firm, even pressure across the tape width to promote adhesive flow into rough substrate surfaces. Follow applicable local codes and manufacturer guidelines for any thermal or electrical insulation assemblies where this tape is used.
