Tapecoat
H35 Gray Tape
Pipe & Pipeline Coating
Cold-applied above and below ground coating
in tape form.
Basic Use
| Tapecoat H35 Gray Tape is
designed to protect above ground, 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.
Its unique "MAF" film backing has been specially
formulated to provide strength that allows it to be pulled
tightly around fittings and other irregular shapes with minimal
pull back due to memory. Tapecoat H35 Gray is resistant to UV
rays, thermal expansion, impact, abrasion and can be applied
over a wide range of ambient temperatures. |

Composition
Tapecoat H35 Gray Tape is composed of
a Gray specially formulated multipolymer alloy film "MAF"
with a synthetic elastomeric adhesive. 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.

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 H35 Gray Tape 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 40°F) a liquid primer will enhance the immediate
bond. TC Omniprime is the compatible primer for use with Tapecoat H35
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 H35 Gray.
Tape Application
- Spiral Wrap: Tapecoat H35 Gray
Tape 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 H35 Gray Tape 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.
