Tapecoat H35 Tape

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.

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.
