Chemical Materials
Precious-metal plating chemistries engineered to work with our equipment — safeguarding deposit quality and environmental compliance at the source.
Stable, compliant, ready to run

Cyanide-free
Cyanide-free agents replace traditional cyanidation and lower wastewater burden.

High-purity salts
Gold, platinum and silver salts with controlled impurities and stable supply.

Complete make-up kit
Make-up agents, brighteners and conductive salts for fast bath setup.

Formula support
Ratio guidance and bath-maintenance plans to stabilize production.
Who it serves
Electroforming processors
Hard-gold, platinum and silver electroforming lines.
Jewelry surface lines
Gold / platinum jewelry plating workshops.
Electronics plating
PCB and electronic-contact plating.
R&D labs
Process and material research trials.
A full chemistry line for precious-metal plating
Yongdarui chemical materials include bath make-up agents, brighteners, conductive salts, and high-purity gold, platinum and silver salts. Our cyanide-free systems are validated on long-running production lines, offering adhesion and brightness comparable to traditional cyanidation while sharply lowering workshop safety risks.
