Permanent Barrier Tape

Patco 585 Dissimilar Metal Tape is a clear polyethylene film designed to create a permanent barrier between dissimilar metals. It prevents electrolytic corrosion in demanding environments such as truck assembly, aerospace applications and machine construction. The tape is supplied in a 36-yard roll with an actual width of 72mm.

Conformable Film Construction

The polyethylene film conforms to irregular surfaces, allowing reliable coverage across joints and seams during assembly. Its clear finish lets technicians inspect the bond line visually without removing the tape. The roll format supports continuous application on production lines or during field repairs.

Corrosion Protection Performance

In normal use the tape maintains a stable insulating layer that blocks the electrochemical reaction between dissimilar metals. It resists moisture ingress and environmental exposure without degrading. The film structure remains intact through temperature cycles typical of heavy equipment and aerospace service.
