Highlights

Rubber adhesive will cross-link when exposed to a thermosetting cycle, providing adhesion and bond strength and higher heat resistance
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
Good solvent resistance produces excellent bond that remains affixed under a variety of conditions

Constructed of a glass cloth backing and a thermosetable rubber adhesive, 3M™ Thermosetable Glass Cloth Tape 365 is an excellent choice for applications requiring high adhesion for a variety of surfaces. It excels particularly well in splicing many materials with rough surfaces or low internal strength such as roofing felts and textiles.

Tape that Withstands
Our 3M™ Thermosetable Glass Cloth Tape 365 (PDF, 11.19 Kb) 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™ Thermosetable Glass Cloth Tape 365 features a rubber adhesive that provides good initial adhesion and high tack. When subjected to a thermosetting cycle it will cross-link, providing 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.

Recommended Applications

Splicing and insulating applications requiring high tensile strength at elevated temperatures
As a corrosion resistant wrap on stainless steel hot air ducts
Splicing materials with rough surfaces or poor internal strength such as roofing felt, fiberglass or textiles
