Tapecoat H35 Gray / H50 Gray
Cold-applied above and below ground coating in tape form with an integrated primer.

Tapecoat H35 Gray and Tapecoat H50 Gray are designed to protect above and below ground metal surfaces from corrosion and electrolysis. They are used for coating pipe, pipe joints, fittings, couplings, tanks, pipe type cable, conduit, tie rods, elevator casings and other metal surfaces. Their unique MAP 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 and Tapecoat H50 Gray employ an integrated primer and are resistant to UV rays, thermal expansion, impact and abrasion. Both tapes can be applied over a wide range of ambient temperatures. The application of liquid primer is not required.

Composition

Tapecoat H35 Gray and Tapecoat H50 Gray are composed of a Gray specially formulated MAF® backing 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 use.

Technical Data

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-SP6 Commercial Blast Cleaning is also acceptable.

Primer Application Not Required

Tapecoat H35 Gray and Tapecoat H50 Gray come with an integrated primer. Liquid primers are not required.

Tape Application

• Spiral Wrap: Tapecoat H35 Gray and Tapecoat H50 Gray are 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 or Tapecoat H50 Gray to a length equal to the circumference of the pipe plus a minimum of 4". Follow general tape applications described above.

Tapecoat 6025 Gray
Cold-applied coating in tape form for use in high temperature pipeline service.

Tapecoat 6025 Gray High Temperature tape with a MAF® backing is designed to protect above and below ground pipe, pipe type cable, pipe joints, fittings, tanks, insulated steam lines, and other metal surfaces from corrosion and electrolysis over a wide range of in-service temperatures up to as high as 250°F (121°C) in constant or peak load operating conditions. Tapecoat 6025 Gray and TC Omniprime may be applied to new pipelines and to pipelines in service operating at elevated temperatures.

Composition

Tapecoat 6025 Gray is composed of a specifically formulated MAF® backing and a synthetic elastomeric, temperature resistant coating.

Technical Data

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. Oil, grease and all other residue are to be removed from pipe surface per SSPC-SP1 Solvent Cleaning. SSPC-SP6 Commercial Blast Cleaning is also acceptable.

Application

• Priming: If operating temperatures do not exceed 180°F (85°C) TC Omniprime is the primer of choice. TC 7000 Epoxy has been developed specifically for use with Tapecoat 6025 Gray when service temperatures are between 180°F and 250°F (85-121°C). Either primer may be hand applied by brush or roller. Let TC Omniprime or TC 7000 Epoxy dry to the touch before applying Tapecoat 6025 Gray.
     
• Tape Application: Tapecoat 6025 Gray is applied by hand, with the Tapecoat Hand Wrapster #3, or by plant or over-the-ditch tape wrapping methods. Tapecoat 6025 Gray is spirally wrapped in two layers. Wrapping tension is to be maintained to obtain conformability of the tape to the surface being coated.
