text: 3M™ Low Static, Non Silicone Polyimide Film Tape 7419 with polyimide film and acrylic adhesive used for PCB solder masking and other high temperature applications. Low Static.
  This high temperature tape utilizes a non silicone adhesive formulation which eliminates concerns about silicone contamination on the masked areas. It also has designed in static dissipative performance attributes and produces very low static charge during unwind and removal making it desirable in static sensitive applications. 3M tape 7419 has been designed to remove cleanly from a variety of typical electronic substrates including FR 4, polyimide, gold, copper, and silicon after high temperature processing.
