***Discontinued*** Anti-Static Masking
Discontinued A 2.2 mil. anti-static masking tape used to mask, hold or protect sensitive electronic components. 42 tape represents a breakthrough in PSA tape technology. This product may be used at static safeguarded workstations as part of your total static control program. When 42 tape is used in high temperature applications, it should be removed by pulling back over itself 180°. The substrate should also be allowed to cool to room temperature. This tape neutralizes triboelectrically generated charges at the instant of separation of surfaces. It also generates very low levels of static charge, even in dry conditions of 10% R.H. 42 tape is opaque with gold tint for easy indentification and differentiation for standard high temperature tapes. Plastic anit-static cores are available to minimize particulate contamination in clean work areas.

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.
