SLOTOPAS ZN 300 is a trivalent chromium black passivate for zinc-nickel alloys, forming a homogeneous black passivate layer on zinc-nickel alloys. SLOTOPAS ZN 300 contains trivalent chromium compounds and is free of hexavalent chromium and fluoride, and should be used in conjunction with subsequent sealers (e.g. Saltan's SLOTOFIN) to increase the corrosion protection and glossy black appearance of the workpiece. This will increase the corrosion protection and the glossy black appearance of the workpiece. The data quoted in this publication are based on laboratory data. The actual dosage in production depends on the material and geometry of the workpiece.
