Scotch Glass Cloth Electrical Tape

3M 27 is a 7.0 mil tape consisting of thermosetting rubber adhesive with a woven glass cloth backing primarily used for insulating, securing, splicing and reinforcing applications. 27 tape is designed to operate in 600volt dry applications requiring high mechanical strength and resistance to high temperatures. The glass cloth backing is specially treated and prepared to provide corrosion-free protection and will not shrink, rot or burn. This tape contains a pressure-sensitive thermosetting adhesive which performs at a Class B temperature of 266°F. All splices for 600volt wire rated at 266°F should be insulated with a minimum of two half-lapped layers of Scotch 27 Glass Cloth Electrical Tape.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.

Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.

Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
