Magni 554 is a chrome-free fastener duplex coating system that combines an inorganic zinc-rich basecoat with an organic aluminum-rich friction-modified topcoat. The inorganic basecoat system is developed for superior heat-resistant corrosion performance and consistent in-process material stability. The organic topcoat system can be adjusted to meet OEM friction requirements while providing outstanding adhesion, heated loosening performance and chemical resistance. Magni 554 can be applied via dip-spin or spray application methods with fewer processing steps, resulting in improved quality at a lower cost.
