Epoxy Coating Specification

Niles Steel Tank’s Epoxy Lining has been formulated to be a superior lining for tanks and vessels. Working closely with formulators and chemical engineers, Niles has developed a strong, heat resistant durable epoxy coating for use in hot water applications. The NST formula is an effective coating against corrosion for potable water storage tanks, water filtration tanks, process tanks and pipe and fittings by providing excellent protection against the destructive nature of hot water.

Niles Epoxy coating is applied to a white-metal, sand blasted to SSPC-SP5 (Society of Protective Coatings). This substrate preparation standard covers the requirements for white metal blast cleaning of uncoated or coated steel surfaces by the use of abrasives. These requirements include the end condition of the surface and materials and procedures necessary to achieve and verify the end condition.

A white metal blast cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dust, dirt, mill scale, rust, coating, oxides, corrosion products, and other foreign matter.

The epoxy coating is applied with a sprayer, roller or brush at a thickness of 5 to 6 mils/ application at ambient room temperatures. A total of 10 - 12 mils is applied. Each coat requires a minimum of 12 hours of dry time and must be tack free between coats. The epoxy coating is then air cured for 72 hours to meet FDA approval.

Niles Steel Tank’s epoxy comes with a 1 year warranty. Anode protection is required even in epoxy lined tanks and are required to be maintained as outlined in our warranty. All tanks are manufactured under ASME Code.
