PTC1 PortHoles Electrochemical Sample Masks, 3x3", 3cm2, 60/pkg

PortHoles™ Electrochemical Sample Masks are fabricated from 3M Model 470 Electroplater’s Tape. Model 470 Tape incorporates a special adhesive to bond aggressively to the metal sample surface to discourage underflow of the tape edge by the electrolyte, which would cause crevice corrosion. The hole in the tape is carefully cut for a smooth edge with minimum burring. Model 470 Tape is formulated to withstand lengthy exposure to chemicals commonly found in electroplating applications.
