3M Scotchrap ™ Primer is specifically for use with Scotchrap ™ 50 and 51 Tapes as part of an overall corrosion protection system and is a quick-drying, non-sagging rubber based primer that permeates metal surface pits and irregularities, preparing the surface for 3M tape application. Please see our Tapes section for details of Scotchrap ™ 50 and 51 Tapes (available separately).

  • Scotchrap Pipe Primer is used as part of the 3M Scotch All-Weather Corrosion Protection System which includes Scotchrap 50 and Scotchrap 51 Corrosion Protection Tapes and also Scotchfil Electrical Insulation Putty. (Available separately on request)

  • 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.

  • Following Surface preparation, Scotchrap Pipe Primer is normally applied in a uniform, continuous coating of the to the prepared surface and then left to. Then irregular surfaces are filled with the Scotchfil putty. Finally the weld bead is covered by wrapping to Scotchfil 50 or Scotchfil 51 tape over the entire surface.

  • Straight pipes and conduit are normally spirally wrapped using tape width listed in coverage table (See 3M data sheet for further information). Field joints on mill-coated pipe can be wrapped spirally or with a "cigarette" wrap or wide tape. Unusually severe construction or soil conditions may
    require additional tape thickness or protective overwraps. Please ensure you refer to 3M data sheets for relevant details.

  • For below ground installation adequate provision should be taken to protect the coating from physical damage during pipe handling, lowering or backfilling operations.
    The pipeline ditch should be free of rock or other sharp objects so the coated pipe rests on a smooth bed of soil. Backfill materials should also be free of rock or other
    sharp objects to avoid damage of the coating. After layer of debris-free soil has covered the pipe, general backfill may be used. For further information contact us and / or refer to 3M data sheets.
