Product Description
3M™ Glass Cloth Tapes 365 and 3650 are thermosetable rubber-resin adhesive tapes
coated onto a strong conformable glass backing for many applications requiring high
adhesion for adhesion to a variety of surfaces. 3M tape 3650 is a poly-linered version
of 3M tape 365.

Features
• This adhesive provides good initial adhesion and tack. When subjected to a
thermosetting cycle it will crosslink, providing greater adhesion and bonding,
higher solvent resistance 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.
• Glass cloth backing for high tensile strength that helps increase productivity.
• Backing will not shrink or rot for excellent application protection.
• Firm at high temperature that helps increase productivity.
• Good solvent resistance to produce excellent bond.
Application Ideas
• Splicing or insulation 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.
