Page 1 of 4 TM Scotchrap 50, 51 and Piper Primer TM Scotchfil Electrical Insulation Putty All Weather Corrosion Protection Data Sheet TM Wrap Your Job Up Right with Scotchrap Tapes Scotchrap 50 and 51 Tapes 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. Scotchrap 50 and 51 tapes are: Resistant to corrosive salt water, soil acids, alkalis and salts, common chemicals, chemical vapours and exposure to outdoor weathering and sunlight. Resistant to impact, abrasions, punctures, and tears. Scotchrap 50 is a highly conformable, all weather 0.254mm (10mil) thick tape designed for application over a wide temperature range. Scotchrap 51 provides similar qualities in a thicker, 0.508mm (20mil) tape. Both tapes have high electric strength, and excellent insulating properties. Scotchrap Pipe Primer Quick dry, non-sag rubber based primer that permeates metal surface pits and irregularities, preparing the surface for tape application. Compatible with the special adhesives on Scotchrap Tapes, it enhances adhesion.

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, ground or filed. Apply a uniform, continuous coating of Scotchrap Pipe Primer to the prepared surfaces and let dry. Fill in irregular surfaces with Scotchfil Electrical Insulation Putty. Cover weld beads with one wrap of tape over the entire surface. 3M UK PLC 3M Ireland 3M UK PLC Electrical Products Sales Office Sales Office 3M Centre, Cain Road 3M House, Adelphi Centre PO Box 393 Bracknell, Berkshire RG12 1JU Dun Laoghaire, Co Dublin, Ireland Bedford MK41 0YE Telephone: 01344 858616 Telephone: 353 1 280 3555 Telephone: 01234 229462 Fax: 01344 858758 Fax: 353 1 280 3509 Fax: 01234 229433 Page 2 of 4 TM Scotchrap 50, 51 and Piper Primer TM Scotchfil Electrical Insulation Putty All Weather Corrosion Protection Data Sheet Straight pipe and conduit are normally spirally wrapped using tape width listed in coverage table. Field joints on mill-coated pipe can be wrapped spirally or with a cigarette wrap of wide tape. Unusually severe construction or soil conditions may require additional tape thickness or protective overwraps. For below ground installation adequate provisions should be taken to protect the coating from physical damage during pipe handling, lowering or back filling operations. The pipeline ditch should be free of rock or other sharp objects so the coated pipe rests on a smooth bed of soil. Back fill 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 back fill may be used.
