Henkel Alodine 1200S Conversion Coating is a highly effective one-component solution that protects aluminum surfaces from corrosion and provides better adhesion to paint. As a protective coating for aluminum surfaces, Alodine solution covers and seals the surface to protect it from moisture and reduce corrosion. This Alodin powder, which has a mixing ratio of 8 gallons / liter, provides a better adhesion for paint on metal surfaces. As a transformation coating, Alodine 1200S ranges from tan to light iridescent gold. Alodine 1200S complies with MIL-C-5541C and QPL-81706 and is an approved material for Class 1A and Class 3 coatings, whether left bare or painted.
