PRODUCT DESCRIPTION
A nominal 75micron (3.0 mil) high tensile strength aluminum foil backing, combined with a high performance flame retardant solvent acrylic adhesive, protected by an easy-release white silicone release paper.
FEATURES
Aluminum backing provides excellent reflection of both heat and light.
High quality adhesive with super strong adhesion and holding power offers reliable and durable Foil-Scrim-Kraft Facing joints and seams sealing in HVAC ductwork application.
Low moisture vapor transmission rate makes BondTape AF7525R an excellent vapor barrier.
Service Temperature range from -30° to +120°C (-22° to +248°F).
