SpeedMask® peelable electronic masks are solvent-free, 100% solids resins designed for the masking of printed circuit board components prior to conformal coating application or wave solder and reflow processes. They cure in seconds “on-demand” when exposed to UV/Visible light. The fast cure allows boards to be immediately processed without the need for racking or waiting. The masks have low odor and require no special venting. The cured materials also leave no silicone, ionic contamination, or corrosive residues.
