3M 365 Thermosetable Glass Cloth Tape

365

3M™ Thermosetable Glass Cloth Tape 365 is a white glass cloth tape with thermosetable rubber adhesive. The conformable backing delivers high tensile strength, solvent resistance, and excellent abrasion and puncture resistance without shrinking or rotting. It is an excellent choice for applications requiring high adhesion for a variety of surfaces. It excels in splicing many materials with rough surfaces or low internal strength such as roofing felts and textiles.

Thermosetable rubber adhesive will cross-link when exposed to a thermosetting cycle, providing adhesion and bond strength and higher heat resistance
Glass cloth backing provides high tensile strength to aid in increased productivity
Durable backing will not shrink or rot and features good abrasion and puncture resistance for extended performance

Color: White

Backing/Carrier Material: Glass Cloth

Adhesive Type: Thermosetable Rubber-Resin

TotalThickness: 8.3 mil

Technical Data Sheet

3M™ Thermosetable Glass Cloth Tape 365 is a white glass cloth tape with thermosetable rubber adhesive. It is designed for splicing textured surfaces, especially those materials which might require high tensile strength at elevated temperatures. The conformable backing provides high tensile strength and good solvent resistance. It will not shrink or rot, and is tough and durable with superior abrasion and puncture resistance. This tape will perform under a wide range of temperatures ranging from 40°F/4°C to 450°F/232°C.

3M™ 365 features a rubber adhesive that provides good initial adhesion and high tack. When subjected to a thermosetting cycle it will cross-link, providing greater adhesion and bond strength and higher heat resistance. Thermosetting is frequently achieved by ironing or heating the backing once the tape is applied. High adhesion is obtained by optimizing the time, temperature and pressure of the heat applied.
