Anti-Corrosion Tape

The BM-T series is a cold applied tape coating system for corrosion protection of above and underground Oil, Gas, Petrochemical and Waste Water pipelines. The tapes are a various combination of a Butyl Rubber Adhesive Layer and a special blend of stabilized PE Film backing. The tapes can be applied by hand or with a wrapping machine. We recommend the use of a BM-P series Primer prior to any Inner Tape Application. The primer not only represents an Anti-Corrosion layer of its own, but also provides a uniformly smooth contact surface for the coating system. Lengths, Widths, Colors, Choice of a Non-Stick Siliconized Release Film, Packaging & Logo Imprints are per customer's specifications.
