It is applied to all metal surfaces to increase corrosion resistance and add a decorative appearance. It is based on applying solvent based epoxy, acrylic, polyurethane, infrared reflective paint and water-based paint by spraying. Wet paint application is done with appropriate primer application. Appropriate surface preparation must be done in order to get high performance from this treatment. If high corrosion resistance is desired, appropriate pretreatment is selected according to the structure of the metal. (Aluminum chromate coating or anodizing for aluminum, phosphate coating for steel, passivation for stainless steel) If it is for decorational purposes then mechanical process is sufficient. (Sand blasting, sanding, vibration and etc.)
Performance Tests
Paint performance is calculated by Surface Appearance (FED-STD 595), Coating Thickness (ASTM B244, ASTM B499), Adhesion (FED-STD-141), Specula Gloss Test (ASTM D523), Impact Test (ASTM D2794, ISO 6272), Ben Test (ASTM B522, ISO 6860) and Corrosion Resistance Tests (ASTM B117).
