RomoCoat HB Coal Tar Epoxy 7260
RomoCoat HB Coal Tar Epoxy 7260 is a two component, polyamide cured, high build coal tar epoxy for long term protection of steel and concrete in immersed and very wet, chemically aggressive environments.
Description
- Two pack coal tar–epoxy coating combining epoxy resin with coal tar to give excellent adhesion, abrasion resistance, water impermeability and resistance to dilute acids, alkalis and many industrial chemicals.
- Designed as a high build barrier coat for submerged, underground and splash zone exposure on steel (and suitably prepared concrete) where long term service is required.
Typical applications
1) Hydropower & water infrastructure
- Hydro electric units: penstocks, draft tubes, spiral casings, water passages and gates carrying raw water to turbines.
- Dam and canal structures: steel liners, sluice gates, guide vanes and steel parts permanently or intermittently immersed in fresh water.
2) Marine & harbour installations
- Harbour and jetty steel: piles, dolphins, fenders, sheet piles, quay structures and submerged/ splash zone steel exposed to sea water, tidal action and abrasion.
- Underwater hull exterior (in conjunction with cathodic protection): outer hull below waterline, bilge areas and other immersed steel, where coal tar epoxy provides an excellent acid/alkali and water barrier under CP systems.
3) Cooling towers & water treatment
- Cooling tower basins, channels, inside/outside of riser pipes and structural members exposed to continuous wetting and mildly aggressive circulating water.
- Water and effluent treatment facilities: clarifier bridges, tanks, contact chambers, sewage and effluent lines where resistance to sewage, salt, dilute acids/alkalis and microorganisms is required.
4) Underground & buried structures
- Underground pipelines, external surfaces of buried steel, foundations, piles and other below ground steel/concrete exposed to moist, acidic or alkaline soils.
- Crude oil and fuel storage tanks (external below grade portions or internal where coal tar is allowed by spec) and bund walls subject to chemical and water attack.
