Fastener Coating
ÁñÁ«appµ¼º½Èë¿Ú 558 is a chrome free, and PFAS free duplex fastener coating system that combines a waterborne zinc-rich base coat with an organic aluminum-rich topcoat. The topcoat can be adjusted to meet various friction requirements while providing outstanding adhesion, heated loosening performance and chemical resistance.
ÁñÁ«appµ¼º½Èë¿Ú 558 can be applied via dip-spin or spray application methods.
