ARC HT-S
Chesterton ARC HT-S is a 100% solids, glass/ceramic-reinforced novolac epoxy coating designed to protect metal surfaces from corrosion and erosion in high-temperature, wet environments. It applies easily by spray, brush, or roller and cures in service, helping reduce downtime.
With excellent adhesion and resistance to thermal shock, ARC HT-S performs in continuous dry conditions up to 347°F and wet conditions up to 302°F. It’s ideal for pumps, heat exchangers, tanks, separators, and offshore equipment—offering a tough, chemical-resistant barrier that extends equipment life.
