Tapecoat HT-MB High Temperature Tape is designed to protect buried and submerged pipe, pipe type cable, pipe joints, fittings, tanks, insulated steam lines, and other metal surfaces from corrosion and electrolysis over a wide range of in-service temperatures up to 250°F (121°C) in constant or peak load operating conditions. Tapecoat HT-MB may be applied to new pipelines and to pipelines operating at elevated temperatures.
Tapecoat HT-MB is a pre-formed, cold applied, self-adhering coating that is impermeable to water and salt. The specially formulated "high temperature" adhesive is laminated to a woven polypropylene backing. The very aggressive adhesive is kept from permanently bonding to its backing by a tough, easily removed polymer release liner, which also prevents contamination of the adhesive prior to its use.
