3M Aluminum Foil Tape 425 is dead-soft aluminum foil tape with a pressure sensitive acrylic adhesive.
Very low moisture vapor transmission rate makes the tapes a good sealant.
The acrylic adhesive, combined with the durable aluminum backing, offers idealÂ properties for long serviceable life in and outdoors.
Good candidate as a maskant in electroplating of aluminum because it will notcontaminate the bath.
Aluminum backing provides excellent reflection of both heat and light.
