Saint-Gobain’s #233 & #233PW crushed cream-colored powders are created using a special fusion process that gives the particles an open structure. These coatings act as an excellent thermal barrier or insulator, providing excellent resistance to thermal shock & particle erosion at temperatures up to 1500° C. The #233/233PW powders are ideal for combustion liners and after-burner parts in jet turbines.

The 233 powder is approved for PW 1333, A50TF155 class A and meets the specifications for EMS 52432 type XXVI and Rolls Royce 9507/21.

Saint-Gobain Coating Solutions manufactures a range of zirconia-based thermal spray powders for thermal barrier coatings with excellent wear resistant properties for high temperature applications such as gas turbines & combustion engines.
