Electrical Insulation Putty
Scotchrap Pipe Primer
A quick-dry, non-sag rubber base 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.
Scotchfil Electrical Insulation Putty
Use as a build-up compound on highly irregular surfaces such
as fittings and valves, providing a smooth, waterproof taping
surface. Scotchfil 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:
Scotchrap tapes 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 Scotchrap Pipe
Primer to the prepared surface and let dry. Fill in irregular
surfaces with Scothfil Electrical Insulation Putty. Cover weld
beads 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
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 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.
