Tapecoat
TC 7030
High-Build, High
Temperature Epoxy
One-coat, stand-alone protection that
exceeds all performance criteria
for corrosion prevention of above and below ground metal surfaces.
Description
Tapecoat TC 7030 High-Build,
High-Temperature Epoxy is a one-coat, stand-alone protection
that exceeds all performance criteria for prevention of corrosion of
above and below ground metal surfaces. This tough coating can be
used for any general application including high temperature
pipelines with a maximum constant operating temperature of up to
250°F (121°C).
TC 7030 is an
environment-friendly two-component, 100% solids material that
provides up to 30 mils of high-build thickness for tough abrasion
resistance-to-backfill and soil stress damage. This surface-tolerant
epoxy provides exceptional corrosion prevention for reconditioning
pipelines, protecting joints, patching pipeline coatings, and
covering irregular fittings and metal surfaces.

Application
Surface must be clean and dry.
Commercial blast to SSPC-SP6. Remove oil and grease with suitable
solvent. Salt and other contaminants may be removed by high pressure
fresh water cleaning. Pour entire contents of Part B Curing Agent
(small container) into Part A Resin (large container), and mix
thoroughly for approximately 3 to 5 minutes. Do not alter the
amounts of A and B in the mixture. Apply epoxy by brush, pad, roller
or spray.
Primer should be dry to touch before
applying Tapecoat hot applied tapes or sleeves. As a stand alone
coating, TC 7030 Epoxy provides superior corrosion protection above
and below ground.
Specially selected Tapecoat
reinforcing scrim can be applied over wet epoxy. After scrim has
been applied, apply a second coat of TC 7030 Epoxy.
Application
Parameters
|
Environment |
Use only when the surface to be
coated is above 40°F (4°C) and the relative humidity (R.H.) is
less than 90%. |
|
Application temperature |
40°F-250°F (4°C-121°C). Surface
temperature must be 5°F
(3°C) above the dew point to avoid condensation. |
|
Cure time |
60 to 90 minutes at 70°-80°F
(21°-27°C) and 50% R.H. Cure time can be accelerated by
preheating the metal surface to 100°F-200°F (38°-93°C). |
|
Recommended coverage |
Single-coat, stand-alone coating: 30
mils (0.76mm) thickness, with a coverage of 53 sq. ft. per mixed
gallon (1.23 m2/liter) |
