The 3M 425 die cut discs are manufactured from a tape that combines a 3 Mil nominal dead soft aluminum foil backing with a transparent arcylic adhesive. A good choice for masking in aluminum electroplating as it won't contaminate the bath. The aluminum backing provides excellent reflection of both heat and light.
