GENERAL INFORMATION

D/W 493 is a 22 mil, glass cloth/aluminum foil masking tape used in plasma flame spraying. These layers are laminated "double-ply" of silicone rubber & glass cloth & coated with a high temperature silicone adhesive. It is used when a single ply tape will not provide sufficient protection. The double ply construction eliminates the need for two hand layup operations, thus saving labor cost.

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.
