3M™ Scotchrap™ Tapes 50, 51 and Pipe Primer, 3M™ Scotchfil™ Electrical Insulation Putty, All-Weather Corrosion Protection Data Sheet Description May 2013 3M™ Scotchrap™ Tapes 50 and 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. These tapes are:  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 50 is highly conformable, all-weather 10 mil (0,254 mm) thick tape designed for application over a wide temperature range. Tape 51 provides similar qualities in a thicker, 20 mil (0,508 mm) tape. Both tapes have electrical insulating properties. 3M™ Scotchrap™ Pipe Primer is a quick-dry, non-sag rubber base primer that permeates metal surface pits and irregularities, preparing the surface for tape application. The primer is compatible with the special adhesives on these tapes, as it enhances adhesion. 3M™ Scotchfil™ Electrical Insulation Putty is used as a build-up compound on highly irregular surfaces such as fittings and valves, providing a smooth, waterproof taping surface. The putty is soft and pliable – simply press putty into place on irregular surfaces, mold with finger pressure and over tape using standard methods. Application of Primer, Putty and Tape: The Scotchrap Tapes 50 and 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. Apply a uniform, continuous coating of the pipe primer to the prepared surface and let dry. Fill in irregular surfaces with the putty. Cover weld bead with one wrap of tape over the entire surface. 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 or wide tape. Unusually severe construction or soil conditions may require additional tape thickness or protective overwraps. 1 of 4 3 3M™ Scotchrap™ Tapes 50, 51 & Pipe Primer, 3M™ Scotchfil™ Electrical Insulation Putty Application of Primer, Putty and Tape, continued For below ground installation adequate provision should be taken to protect the coating from physical damage during pipe handling, lowering or backfilling operations. Typical Properties Not for specifications. Values are typical, not to be considered minimum or maximum. Properties measured at room temperature 73°F (23°C) unless otherwise stated. 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. 3M™ Scotchrap™ Pipe Primer Property Typical Value US units (metric) Color Black % Solids 30 Weight 7lbs. /gal.
