3M 427 Aluminum Foil Tape
3M™ Aluminum Foil Tapes 427 combine a 3 mil nominal dead soft aluminum foil backing with a transparent acrylic adhesive. 3M aluminum foil tape 427 offers an easy-release liner. The acrylic adhesive, combined with the durable aluminum backing, offers ideal properties for long serviceable life in and outdoors. Good candidate as a maskant in electroplating of aluminum because it will not contaminate the bath. Aluminum backing provides excellent reflection of both heat and light. Best results obtained when applied to a clean, dry surface above 32°F (0°C).
Applications: Aircraft paint stripping maskant, moisture barrier in “white goods” appliances, general purpose heat reflector and heat dissipater, mechanically hold wires and cooling coils in “white goods” appliances, repair tears on truck trailers and aircraft, splicing of thin gauge foils, and general purpose holding, patching, sealing applications – indoors and out
