Salt bath paint removal

Salt Bath Method. The object from which the paint is to be removed is immersed in a salt melt heated to 300-500 C. The short time required for paint removal (30-120 s) is the result of the spontaneous heat transfer and high oxidation potential of the salt melt (e.g., alkali nitrates). 

Fused State Baths. Sodium hydroxide and salt can be heated to a fused state in baths to allow the removal of finishes from ferrous metals. The most common use of this method is the removal of heavy concentrations of paint on conveyer parts and hangers used in production spray systems.
