The 3M™ Thermosetable Glass Cloth Tape 3650 is an 8.3 mil (0.20 mm) glass cloth tape with thermosetable rubber-resin adhesive. This white tape has a blue film liner and is a poly-linered version of the 365 tape. Use this product for applications requiring high adhesion. It has a very strong conformable backing and excellent heat resistance.
Good initial adhesion and tack for reliable performance
Thermosetable rubber resin adhesive provides durability and longevity
Linered tape for die-cutting applications
Delivers high adhesion and conformable backing to withstand tough conditions
Resists many solvents to extend life of product and expand range of applications
Heat activated adhesive system provides high temperature resistance for use in insulation applications
Our 3M™ Thermosetable Glass Cloth Tape 3650 is all about toughness and durability; from the time it’s first applied and throughout the tape’s use. It begins with good initial adhesion and tack when the tape is applied. Once applied, this product offers high tensile strength, solvent resistance – as well as puncture and abrasion resistance. Bottom line: this tape is built for those difficult jobs, especially splicing or insulation applications.
Splicing or insulation applications requiring high tensile strength at elevated temperatures
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
Excellent Heat Resistance
Our 3M™ Thermosetable Glass Cloth Tape 3650 provides a heat activated system for superior bonding and a temperature resistant backing that make it ideal for high temperature applications – up to 450°F (232°C). These features are combined with the high holding power and flow properties of the thermoset adhesive that allow this tape to work well for splicing many materials with rough surfaces or low internal strength such as roofing felt and textiles. Collectively these superb features make this product suitable for several applications across a number of industries including: transportation, specialty vehicle, construction, automotive, military and government, general industrial and aerospace.
