Denso Protal 7200 Repair Cartridges are specially formulated for patching and repairing damaged FBE and other liquid-coated pipelines. The repair cartridges are packaged in 2-component tubes that are applied with a dispensing gun (sold separately). Two convenient sizes (400 mL and 50 mL) are available.

Repair coating for damaged FBE and other liquid coated pipelines. Also used as coating of Cadweld areas.

Excellent adhesion (compliments FBE coated pipe)

High build (in one coat)

High abrasion resistance for drilling applications

Does not shield cathodic protection

Application

Repair areas shall be roughened using Carborundum cloth or 80-grit sandpaper and wiped clean with an isopropyl alcohol soaked cloth prior to patching. Material can be applied by injecting material into a small container and mixing until a uniform color is achieved. Material can then be brush applied to specified mil thickness (minimum 20 mils). Cure times are dependent on temperature and will be extended at cooler temperatures.
