Fireside Coatings Spray on Ceramic XP61-S

​Anti-Slagging Ceramic Coating for boiler tubes

​XP61-S is a single component ceramic coating engineered for boiler tube corrosion protection.  Fireside Coating XP61-S has high surface lubricity and sliding abrasion resistance on both carbon and stainless-steel boiler and furnace tubing. XP61-S is formulated to stop slag build up on boiler water walls and to prevent fouling in elevated temperature generating sections of coal fired utility boilers.
The Ceramic is applied to a dry film thickness of 150-400 microns. 

XP61-S is thermally neutral.  It bonds well to carbon steel or stainless-steel substrates.  Upon curing XP61-S becomes a durable ceramic coating that will provide protection of metal surfaces to 982° C and will withstand thermal cyclic conditions to 1093° C.
