Epoxy Powder Coated Insulation

The way of powder coating works is that powder of a certain color is sprayed onto the metal surface, which holds an electrical charge. The charge causes the powder to adhere to the surface, and it is baked on once the spraying is done.  

Insulation powder coating is a specialized type of powder coating that is designed to provide thermal insulation properties. It involves applying a powder coating material with insulating characteristics to the surface of an object to reduce heat transfer.
