Key Features
Used as a primer in coating systems for steel structures in marine oil & gas, offshore structures, bridges, wind power, petrochemical, chemical, and construction industries; Offers exceptional anticorrosive performance; Excellent fast-drying allows for short recoating intervals; Features good cutting and excellent welding characteristics.
Recommended Use
Primarily used as a shop primer (pre-construction primer) for blast-cleaned steel structures on automated priming lines to prevent corrosion during transfer, storage, and fabrication. Features excellent fast-drying properties to suit various assembly lines. Exhibits good cutting and excellent welding characteristics. Provides superior resistance to oil, seawater, weathering, antistatic properties, and high temperature (up to 400°C). Strong adhesion, high wear resistance, and resistance to long-term wind erosion. Good compatibility with topcoats, including Epoxy, Vinyl, and Chlorinated Rubber. Low fume generation during cutting and welding.
