Offers superior iridescent protective layers, surpassing 120 hours of salt spray testing before white rust development.
Specifically developed for high-end automotive fasteners requiring premium corrosion protection under thermal stress.
An eco-friendly, high-throw copper plating catalyst eliminating cyanide emissions while improving bonding strengths.
Unparalleled deposit uniformity and moderate wear resistance for precision tooling and machinery components.
The Chicago-Naperville-Elgin metropolitan region remains one of the largest metal fabrication and manufacturing hubs in the United States. Metal stamping shops, automotive Tier-1 suppliers, and wind energy components manufacturers across Illinois demand high-quality surface treatments. With local EPA enforcement and Metropolitan Water Reclamation District (MWRD) guidelines placing rigorous limits on heavy metals, trivalent passivation agents (Cr3+) have transitioned from an optional choice to a mandatory standard.
Conventional hexavalent chromium (Cr6+) treatments are heavily restricted due to environmental hazards. Our range of trivalent passivates and cyanide-free chemical additives is engineered to meet ASTM B633, ASTM A967, and automotive standards (such as Ford WSS-M21P17 and GM7111M). These technologies deliver equivalent or superior sacrificial corrosion protection, allowing local operators to meet environmental compliance without sacrificing part longevity.
Passivation is not merely an immersion step; it is a controlled chemical reaction. The trivalent zinc passivation process forms a complex, self-healing hydrated chromium oxide layer over the electroplated zinc or zinc-nickel alloy layer. Our formulations balance pH levels, film-building accelerators, and nanoparticle silica to guarantee consistent, uniform deposit layers across complex geometries.
Our specialized formulations address specific engineering requirements, from wear-resistant electroless nickel to high-throw alkaline zinc alloy systems.
Designed for maximum brightness, rapid deposition, and uniform thickness. Includes semi-bright, bright, and pearl nickel configurations.
Auto-catalytic chemical plating providing precise coating thickness over irregular configurations without electric currents.
High-performance alloys and eco-friendly alkaline systems serving the automotive fastener and structural metal industries.
