***Discontinued*** Varnished Cambric
Discontinued 2510 is a 7mil, varnished coated cotton cloth without an adhesive, primarily used for insulating bus bars, motor leads (for re-entry), and service drop connections. Scotch® Varnished Cambric Tapes are made from straight cut woven cotton cambric fabric. The fabric is oil primed and coated with a high grade yellow electrical insulating varnish. Varnished cambric tapes are flexible, electrically insulating and moisture resistant with a smooth finish. 2510 tape is yellow, non-adhesive coated and 7 mils thick. 2520 tape is yellow, with a pressure sensitive adhesive and 8 mils thick. They are designed to perform continuously in temperatures up to 220°F with excellent resistance to abrasion, puncture and cut-through. The adhesive on 2520 tape holds the tape in position after application.

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.
