Conductive ElectroMask Tape
ElectroMask conductive foil tape with release mask is a tinned
copper tape with peel off mask that allows for high temperature
adhesion to withstand curing after painting.
The tape provides a conductive, non-corroding surface when
applied to clean metal frames, doors, or panel
surfaces where electrical conductivity is required. The release mask
is easily removed from the foil layer after painting. The remaining
foil leaves a clean, electrically conductive path as a mating surface
for an EMI gasket.
ElectroMask Tape with release mask is offered in
continuous rolls of 108 feet (32,92 m), or custom
die-cut shapes.
Application Instructions
