Tapecoat
TC 7100
Wet Bond Gray Epoxy
One-coat, two-part epoxy system which can be
applied underwater
for corrosion protection of wet metal surfaces in or out of water.
Description
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.
Application
-
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.
