P.E.Anti-Corrosion Tape Primer

Product Detail Information

SHAIC AC-700 SERIES are designed for provide reliable corrosion protection and mechanical resistance to metal pipes, underground steel pipes, and bare bends and girth weled joints of PE, Epoxy & PP coated pipes by hand or machine application. The main material used is a stabilized polyethylene backing and butyl rubber based synthetic elastomer adhesive, especially in case of joint wrap, bitumen based synthetic elastomer adhesive available. SHAIC AC-700 SERIES are used Inner wrap, Outer wrap and Joint wrap by customers requirements with various sizes.

  • High chemical resistance under bad condition of soil
  • Excellent working efficiency by hand or machine
  • Wide range of application and service temperature
  • Manufactured at ISO certified facility
  • Complies with AWWA C-209 & C-214 Standard

Sub-Materials

  • SHAIC AC-700 PRIMER
    : Anti-Corrosion Primer of synthetic resin & rubber blended with solvent, 20 liter per can or 200 liter per drum.
    160g/m2 of Coverage.
  • MASTIC FILLER
    : Filler for uneven areas. 3.0mm 40mm 6.0m per roll

Simple Application

Remove rust, dirt, moisture, burr grease, knurl & all foreign matters completely by dry cloth, scrapping, wire brushing, disc grinding, sand or grit blasting. Stir Primer container well and apply it on the surface evenly by brush or roller. Allow curing for about 10min. Apply spirally SHAIC AC-700 P.E.Anti-Corrosion Tape and tension should be enough to obtain conformability to surface being applied. Minimum 25mm overlap, but 50% overlap(equal to two layers) recommended for optimum performance.

According to specification of the project, inner and outer tape can be applied. In case of welded joints, apply Primer on all surface to be wrapped and then Mastic Filler Tape along with weld beads and press firmly. Beginning at a point 25~50mm backward from end of left bare pipe, apply SHAIC AC-700 P.E.Anti-Corrosion Tape spirally to a point 25~50mm forward from end of right bare pipe.
