K-850A is a heavy-duty aluminum foil tape engineered for demanding sealing, masking, and thermal management applications requiring maximum durability and strength.
Constructed with a 5 mil dead soft aluminum foil backing and a solvent-based acrylic adhesive, it delivers excellent conformability along with enhanced thickness for improved protection and performance.
Designed for harsh environments, K-850A is ideal for vapor barrier sealing, waterproofing, and heat reflection applications where added thickness and durability are critical.
