ARC S2
Chesterton ARC S2 is a durable, glass-reinforced novolac epoxy coating engineered to protect metal and concrete surfaces from severe corrosion, erosion, and chemical attack in harsh environments. With a 100% solids formulation, it forms a tough, impermeable barrier that resists permeation, thermal shock, solvents, and continuous temperatures up to 175°F dry and 140°F wet.
Designed for demanding industrial use, ARC S2 applies easily by spray, brush, roller, or squeegee in a single high-build coat. It adheres strongly to both well-prepared and marginal surfaces, making it ideal for pipelines, tanks, valves, separators, and dryer hoods in chemical plants, offshore platforms, and wastewater systems—extending equipment life and minimizing maintenance downtime.
