F- 61 Ceramic Boiler tube coating:
F-61 is a ceramic coating made to prevent corrosion and erosion of boiler tubes in PC power plants.
F-61 is a high solid coating system applied to a dry film thickness of 150-500 μm. Fireside F-61 does not contain VOC's. F-61 is thermally conductive and bonds well to properly prepared carbon steel or stainless steel substrates and increases thermal efficiency. F-61 ceramic organic composition is very stable and does not outgas, nor cause skin irritations like many other high temperature coatings. Cured F-61 is a durable ceramic coating that will provide protection to boiler tubing and other steel substrates to 1093° C
Fireside Coatings F-61 is used as a thermal spray sealer and under insulation or fire brick to prevent “cold side” and high heat corrosion.

Surfaces to be coated must be dry and free of all chlorides, weld splatter, oil, dirt, grease, liquor, and all other contaminants. Round off all rough welds and sharp edges. Abrasive blast to a SSPC-SP5 (white blast) specification. Garnet or other hard sharp materials are recommended for abrasive blasting.
Usually F-61 can be cured using normal equipment start-up procedures. If controlling the cure, do not exceed 200° F (93° C) for the first hour. After one hour the coating can be accelerated 100° F (38° C) per hour, until full boiler operating temperature is achieved.
All equipment should be cleaned with soap and water before the coating dries.
