K-803 is a heavy-duty aluminum foil tape engineered for sealing, masking, and heat management applications requiring durability and strong adhesion.
Constructed with a 3 mil dead soft aluminum foil backing and a high-performance solvent-based acrylic adhesive, it provides excellent conformability and long-term bonding across irregular surfaces.
Designed for demanding environments, K-803 is ideal for aerospace masking, appliance assembly, vapor barrier sealing, and heat reflection applications where reliability and performance are critical.
