Gray Coat
Graycoat is a paste-like wax compound that is used to prevent corrosion of irregular surfaces and small-diameter pipe. It requires only minimal surface preparation and no primer. Graycoat is easily applied by hand and is then overwrapped with Trenton Poly-Ply or Guard-Wrap. It can be backfilled immediately.
Description
Graycoat is a blend of petrolatums, plasticizers, solvents, pigments, and corrosion inhibitors used to prevent corrosion of underground structures. It's mastic consistency makes it easily applied to bolts and other irregular shapes, by hand or trowel. It can be applied over wet pipe with no primer required and requires no waiting or curing before backfilling. Packaged in convenient 24# pails, it is available in both winter and summer grades.
End Use
For protection of irregular metal fittings and straight pipe in conjunction with poly-ply wrapper.
