Chesterton ARC MXHT High temperature severe wear compound (discontinued **)
Categories:	Ceramic; Polymer; Thermoset; Epoxy
Material Notes:	Description: An advanced ceramic composite for the protection of all metal surfaces subjected to severe erosion, abrasion and chemical attack at elevated temperatures. It is applied at a thickness of 6mm (1/4”) or more. It is a 100% solids, non-shrinking coating. ARC MXHT is formulated with a high concentration of ceramic breads and fine ceramic particles for extremely abrasive environments where superior protection is needed. ARC MXHT is applied to a primed surface by trowel. It is chosen over ARC MX1 when abrasion resistance at elevated temperature is required. Benefits: Outlasts other wear resistant materials and coatings by 5-7 times Excellent wear characteristics extend equipment’s operating cycles Outperforms weld overlay or ceramic tiles Tough resin structure resists thermal-mechanical shock. Use in pH range 2-14 up to 130°C/266°F (wet service) and 230°C/466°F (dry service) No need to post cure Suggested Uses:Pumps Elevated Temperature Fans/Blowers/Cyclones Hoppers and Silos Kiln Exhausters Boiler Slag Systems Electrostatic Precipitators Information provided by Chesterton
