Products / Surface and Finish / LUMISEAL™
The Lumiseal™ coating, which is one of the four steps in the surface treatment process used for aluminum, is the catalyst for a chemical reaction during the electrostatic application of the Lumital™ finish. This reaction increases both the protective capacity of the coating and the adherence of the finish, creating a bond between the material and the finish. The surface treatment process for steel involves six steps, including hot phosphating. This process deposits a layer of zinc phosphate that will protect the surface finish against corrosion in case the surface finish is damaged.
