Powder Coating Fiberglass
The most common primer for fiberglass when using a powder coat finish is some formulation of iodine solution applied thinly by spraying or dipping the object in it. The iodine mixture promotes conductivity so that the electrostatically charged powder coat particles will be uniformly attracted to the object or part being coated.
Once the primer is uniform and set, but not necessarily dry, the finish powder coat can be sprayed onto the object in multiple coats as needed to achieve desired texture and finish.
Once coated, the object is heat cured in an industrial ultraviolet or infrared oven at between 300 and 400 degrees Fahrenheit, according to particular powder coat manufacturers' instructions. Once cooled, the finish is hardened and more durable than a liquid paint finish.
