T-Tape Gray PE by Tapecoat
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.
