Pot life 4 h; recoat 24 h–7 d.
Water and chemical resistance; strong anti-permeation.
PLHL52-1 Epoxy Bitumen Glass Flake Coating is a two-component epoxy bitumen glass flake coating for heavy-duty protection of steel and concrete in underground/underwater service and internal linings. This coating is intended for underground and underwater steel structures and concrete facilities, and for internal lining protection.
It is composed of epoxy resin, coal tar pitch, glass flakes, solvent, and additives, with a modified amine curing agent, and is supplied as Part A and Part B.
Designed for heavy-duty protection of steel and concrete.
Suitable for underground service.
Suitable for underwater service.
Suitable for internal lining protection.
Can be used on steel structures and concrete facilities.
This coating is suitable for a wide range of steel and concrete protection projects in industrial and underground or underwater environments.
Underground steel structures.
Underwater steel structures.
Concrete facilities in underground service.
Concrete facilities in underwater service.
Internal lining protection.
Gas holder and tank bottom plates.
Underground mines.
If applied over a two-component primer, surfaces must be clean, dry, and free of contaminants; abrade if beyond the maximum recoat interval. If used directly as the first coat, blast to Sa 2.5 or power-tool clean to St 3; surface profile 30–75 µm.
Storage
store in a dry, cool, ventilated place; keep away from fire; avoid strong sunlight; no outdoor storage.
System compatibility includes epoxy zinc-rich primer, inorganic zinc-rich primer, and epoxy bitumen glass flake coating.
