Discover our primary catalog of high-performance surface treatment additives and electroplating solutions designed for critical durability and precision specifications.
As global environmental standards tighten under REACH, RoHS, and local EPA mandates, chemical formulations for electrodeposition must balance ecological compatibility with structural reliability. Traditionally, cyanide-based copper electroplating served as the gold standard for creating strong adhesive strikes on multi-metal surfaces. Today, our 372 Alkaline Cyanide-Free Copper Plating formulation demonstrates that switching to cyanide-free alkaline plating not only ensures ecological safety but also enhances surface morphology and mechanical integrity.
Alkaline bright copper systems operate on complex chemical configurations where chelation plays a key role. Unlike acid copper baths, which deposit copper rapidly but have limited throwing power on complex geometries, alkaline formulations deposit metal in a more controlled manner. This is done by binding copper ions ($Cu^{2+}$) within an organic chelate matrix, preventing spontaneous immersion deposits on active metals like steel, zinc die-casts, or aluminum alloys.
By controlling the concentration of the complexing agents, the bath achieves a high polarization effect. High cathodic polarization ensures that copper deposits uniformly, even in low-current density areas such as deep recesses, blind holes, and complex threads. This is crucial for applications that require a robust copper strike before subsequent nickel, chrome, or precious metal plating.
Alkaline bright copper plating plays a vital role across multiple major manufacturing sectors. Our solutions are designed to meet strict performance standards, providing high-quality coatings that extend product lifetimes and improve electrical conductivity.
Our solutions provide excellent micro-level uniformity for HDI PCBs and IC packaging. The alkaline copper strike serves as a reliable undercoat, preventing copper diffusion and ensuring excellent wire bonding and solderability in high-frequency circuits.
Designed for battery busbars, high-voltage connectors, and engine control units. In electric vehicles, these copper deposits ensure low electrical resistance and high thermal dissipation under heavy current loads, preventing system failures.
Protects electrical distribution equipment, fasteners, and fluid valves. The dense copper barrier prevents hydrogen embrittlement during steel treatment and serves as an ideal base for highly corrosion-resistant nickel/zinc coatings.
