Our solutions
Solutions for every stage of the finish.
Six families of chemistry, from cleaning and pretreatment through plating and passivation to bath analysis and wastewater treatment.
Featured solutions
Where we are pushing the chemistry.
Seven processes we recommend first. Each links to its product page and, where shown, to a full process line.
Zinc–nickel boltsZinc–nickel system
ZiNYX + Trilux 751 / 671
Alkaline zinc–nickel with uniform 12–17 % nickel, finished with passivation made for Zn-Ni: Trilux 751 blue (NSST 240 h, no white rust) or Trilux 671 black.
Acid zinc
ecozin 570
Water-based acid zinc additive for barrel and rack, with excellent brightness and ductility. Works in ammonium, potassium or mixed baths.
Non-cyanide copper
Ancuma 1575
Non-cyanide alkaline copper with performance similar to cyanide copper, for safer strike and plating lines.
Iridescent & yellow passivation
Trilux µ89 + 551
Trivalent iridescent (Trilux µ89) and yellow (Trilux 551, NSST 120 h, no white rust) passivation for zinc, with high corrosion resistance without top coat.
Blue zinc bolts & nutsBlue passivation
Trilux µ79 + 521
Trivalent blue passivation for zinc with the characteristic bluish-silver look. Trilux 521 reaches NSST 96 h with no white rust.
Alkaline zinc
CK 100
Alkaline zinc with high plating efficiency and excellent metal distribution, and a good appearance after hydrogen embrittlement relief.
Wastewater treatment
HMC-410
Heavy metal capture agent for plating wastewater. Captures metals that are hard to precipitate, removing many metal ions at once to very low residuals (Cu, Zn, Ni, Cd < 0.01 mg/L).
