As with every surface treatment, DACROMET & GEOMET requires a perfect surface cleaning. A mechanical preparation is generally preferred but chemical cleaning can also be approved for many types of components.
Parts to be treated in bulk or on racks are covered with a wet film by film immersing in a cold aqueous dispersion, without any electrolytic action. The use of a pneumatic electrostatic spray gun is an alternative method of applying the coating.
The final structure of the coating is achieved by curing at about 300 deg C. This advantage develops the properties of adhesion and corrosion, resistance for the film.
Two coats are minimum for bulk dip-spin treatment. Parts treated by other coating methods can have either a single or multiple layers.
