Preferred Powder Coating is an experienced MIL-SPEC compliant supplier of Chemical Agent Resistant Coatings (CARC) to the defense industry and the United States Military.

Our CARC coatings, usually epoxy or polyurethane, are formulated and rigorously tested to provide the required resistance to the harsh, corrosive decontaminating chemicals that are used to wash down military equipment.  Especially vehicles exposed to chemical warfare agents such as nerve gas.

Surfaces coated with our CARC systems will resist the penetration of radioactive, chemical, and biological contaminants.
