ALTIC H.R. Silver Paint 250°C is based on a phenolic and bituminous binder system, providing exceptional mechanical strength and chemical durability. The coating cures at room temperature and develops a hard, tough film upon heating to 250°C. Once cured, it offers unmatched resistance to corrosion, moisture, and temperature variations — making it ideal for industrial and engineering applications.
This paint is designed to withstand continuous temperatures up to 200°C and intermittent heat exposure up to 250°C, making it suitable for exhaust systems, heat drums, furnaces, silencers, ovens, chimneys, and other heat-conducting components.
