3M Scotchrap Tapes 51 are tough, polyvinyl chloride based tapes with special high tack adhesives formulated to resist corrosion of metal piping systems above and below ground, fittings and joints on all mill-coated pipe and electrical conduit systems. 

FEATURES:

  • Resistant to corrosive salt water, soil acids, alkalies and salts, common chemicals, chemical vapors, and exposure to outdoor weathering and sunlight.
  • Resistant to impact, abrasions, punctures, and tears. Tape 51 provides similar qualities in a thicker,
    20 mil (0,508 mm) tape. Both tapes have electrical insulating properties.

APPLICATIONS:

  • The Scotchrap Tapes 51 are easy to apply without special tools or dangerous flame. However, a few general application procedures should be followed to obtain optimum performance. Surfaces to be wrapped should be clean, dry and free of oil, grease, and other contaminants. Blast removal of rust and scale is preferred. Welding slag and spatter, sharp edges or burrs should be chipped, grinded or filed.
