3M™ Aluminum Foil Tape 425 combines a 3 mil nominal dead soft aluminum foil backing with a transparent acrylic adhesive.
Product Features
Temperature Rating: 300° F / 149° C
The very low moisture vapor transmission rate makes these tapes a good sealant
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
