Tapecoat®
M50 RC Gray®
Tape
Heavy duty pipe coating in tape
form to protect pipeline
and infrastructure from corrosion.
Basic Use
From the Gray Tape Series of Integrated
primer tape, Tapecoat M50 RC Gray is designed to protect buried
or submerged metal surfaces from corrosion and electrolysis. It is used
for coating pipe, pipe joints, fittings, couplings, tanks, pipe type
cable, conduit, tie rods, elevator casings and other metal surfaces.
Tapecoat M50 RC Gray is resistant to thermal expansion, impact and
abrasion.
Composition
 Tapecoat
M50 RC Gray is a pre-formed, cold-applied, self-adhering material
that is impermeable to water and salt. The adhesive is manufactured
from specially formulated elastomeric resins bonded to a woven highly
puncture resistant polymer. Blended in the adhesive is an "integrated
primer." This primer is kept from permanently bonding to its backing
(while in the roll) by a tough, easily removed polymer release liner,
which prevents contamination of the primer and adhesive prior to its
use.

Application
Surface Preparation
 Surface must be clean and dry. SSPC-SP3
Power Tool Cleaning is recommended to remove any loose rust and scale,
dust or dirt. A "Tack Cloth" for removal of fine dust
particles is provided in each carton. Oil, grease and all other residue
are to be removed from pipe surface per SSPC-SP1 Solvent Cleaning. SSPC-SP
6 Commercial Blast Cleaning is also acceptable.
Primer Application
Because M50 RC Gray comes with an
"integrated primer" built into the tape, normal liquid primers
are not required. However, if the application is taking place in periods
of extreme cold (below 32°F), a liquid primer will enhance the immediate
bond. TC Omniprime is the compatible primer for use with Tapecoat M50 RC
Gray. Apply primer to the prepared surface by brush at the rate of
approximately 300 square feet per gallon. Let primer dry before applying
Tapecoat M50 RC Gray.
Tape Application
- Spiral Wrap: Tapecoat M50 RC Gray is
applied by removing the release liner and spirally wrapping in a
single thickness with a continuous overlap of tape. Tension in
wrapping should be enough to obtain conformability to the surface
being coated.
- Cigarette Wrap: Precut strips of
Tapecoat M50 RC Gray to a length equal to the circumference of the pipe
plus a minimum of 4". Follow general tape application
instructions described above.
NOTE: Tapecoat 2025 (Terra Shield)
Rockshield is recommended in areas where soil stress is expected.
