Tapecoat®
T-Tape Gray®
PE

Cold-applied, below-ground coating
in tape form
to protect pipeline
and infrastructure from corrosion.


Basic Use
Tapecoat T-TAPE Gray PE 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 surfs. Its flexible polyethylene film backing has been
specialty formulated to provide strength that allows it to be pulled
tightly around fittings arid other irregular shapes with minimal
pull-back due to memory. Tapecoat T-TAPE Gray PE is resistant to thermal
expansion, impact, abrasion and can be applied over a wide range of
ambient temperatures.
Composition
Tapecoat
T-TAPE Gray PE is composed of a specially formulated polyethylene
film with a synthetic elastomeric adhesive. Laminated to 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 T-TAPE Gray
PE 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 T-TAPE Gray PE 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.
