The visual effect achieved from the final headlamp reflector is of the utmost importance and a quality powder primer is the key. The powder coating covers defects in the fabricated part and provides a smooth, corrosion resistant and high reflection finish for the vacuum metallization process. MT-A1270 is an epoxy coating for the application to headlamp reflector casing to provide corrosion protection with a high degree of smoothness in a thin film, prior to the process of metallization under vacuum.

Steel surfaces to be coated must be clean and free from grease. For maximum protection it is essential to pre-treat components prior to the application of MT-A1270. Iron Phosphate and Zinc Phosphate of ferrous metals improve corrosion resistance.
MT-A1270 powders can be applied by manual or automatic electrostatic spray equipment. It is recommended that for consistent application and appearance product be fluidized during application.
