Tapecoat TC® 7100 Wet Bond Gray Epoxy is a surface tolerant epoxy developed for coating metal and concrete above and below fresh water. It provides an exceptional anti-corrosion coating for protecting bare steel, welded joints on factory-coated pipe, irregular fittings and surfaces.

TC 7100 is an innovative coating which can be applied underwater for the repair of damaged coatings on steel transmission pipes; steel, concrete, and sheet pilings; and lateral supports. It is ideal for above and below ground protection of metallic surfaces on pipes and compressor / pumping stations that endure splashes, condensation, or humidity.

TC 7100 is a two-part liquid epoxy system which can be used on damp, wet or dry metal surfaces as a one-coat stand-alone protective coating system for above and below grade application.

Surface Preparation

Remove all contaminants that would impede bond. Use effective cleaning procedures to remove: salts, rust, dirt, oil and grease. This may include the use of high pressure fresh water cleaning, using suitable solvents or detergents to SSPC-SP-1, abrasive blast to SSPC-SP-6, or wire brush clean to SSPC-SP-2.


  • Environment: Use only where application and curing can proceed at temperatures above 40°F (4°C). The temperature of the surface and that of the coating itself must also be within these limits. Apply only on a clean surface. (See detailed Field Specifications for complete instructions.)

  • Mixing: Pour entire contents of hardener container into the resin container and mix thoroughly until homogeneously mixed, approx. 3-5 minutes.

  • Application Method: Apply epoxy by brush, pad or roller.
