Thermal Stripping Process

Thermal stripping is a process involving the removal of coatings by means of heating. The process involves heating of the parts to temperatures of about 400–500 degrees Celsius after which the components are washed off by use of a power hose. It is only suitable in decomposing coats that are of organic materials example paints, powders, and varnishes. Inorganic materials for instants sand, glass fiber, and some paint pigments, are not removed by this process due to their inorganic nature. They may fall off or remain on the body in the form of ash residues after thermal stripping, if present. The organic compounds that usually hold the inorganic ones together are removed, weakening them. So after completion of the cleaning cycle, they are easily removed by either washing or wiping them off. There are three types of thermal stripping; these are: burn-off, fluidized bed, and bake-off. The only key to using this method is that the parts or hangers should have high resistant to the temperatures used in the furnace. Thermal stripping is highly recommended as it does not pollute the environment and is  relatively fast, 4-5 hours.
