Features
? Flame resistant. Meets U.L. 746C (File E 122798) and 723, Class “L” low
flammability rating (File R 7311).
? 3M aluminum foil tape 425 can be certified to meet SAE-AMS-T-23397 and L-T-80B.
? Meets requirements of F.A.R. 25.853(a).
? 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.
? Best results obtained when applied to a clean, dry surface above 32°F (0°C).
