Saint-Gobain’s #222 is buff-colored hollow sphere powder that produces highly effective, corrosion-resistant thermal barrier coatings. The spherical shape provides for more uniform delivery without pulsing or plugging of feed lines. The hollow particle morphology contributes to more complete melting, yielding maximum deposit efficiencies.
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’s #235 & #252 are fused calcium oxide stabilized zirconia powders used to produce thermal barrier coatings with excellent resistance to heat & thermal shock. These yellow, blocky-shaped powders are used in both gas turbines and steel furnace parts.
Saint-Gobain’s #235 is approved for PWA 1312 & meets specifications for Honeywell EMS 52432 class XII, Boeing BMS 10-67 Type 5, Allison Gas Turbine EMS 56720 & Rolls Royce 9507/18.
Saint-Gobain’s #290 is a blocky-shaped, fused thermal spray powder that is grayish-blue in color. This powder produces a dense, hard coating that resists wear due to abrasion, fretting, cavitation & particle erosion.
Due to its excellent wear & corrosion resistance, Saint-Gobain’s #290 powders are ideal for coating rolls used in zinc molten metal baths.
