A three-component product based on a specially modified vinyl ester resin, combined with suitable reactive diluents and additives. Before application, mix uniformly according to the metering ratio and it is ready for use. The film has excellent adhesion to both metal and concrete surfaces, with high resistance to chemical media, temperature variation and fatigue.
Specifically designed for the anti-corrosion priming coat on the inner walls of FGD system absorber towers; also suitable for some areas in contact with other corrosive chemical media; regarding the types of applicable media, please consult the company.

Steel surface: remove oil and grease from the surface with a cleaning agent, blast to ISO 8501:2007 Sa2.5 or by hand, surface roughness 40–75 µm. Concrete surface: cured for more than 28 days, moisture content not higher than 6%; in FGD application systems, the surface must be sweep-blasted and dust removed by vacuuming, and the surface kept clean and dry.
Application conditions: ambient temperature 5–40 °C, substrate temperature at least 3 °C above the dew point, and good ventilation at the application site.
