Product Info

DAIN SILVER GPE is an environmentally friendly, cyanide-free silver plating process that supports direct plating on stainless steel (SUS) and is compatible with resist patterns. Offered by DAIWA FINE CHEMICALS (THAILAND) CO., LTD., it ensures high-performance, flexible silver finishing for various industrial applications.

DAIN SILVER GPE – Cyanide-Free Silver Plating Process
DAIWA FINE CHEMICALS (THAILAND) CO., LTD. provides the DAIN SILVER GPE process, a non-cyanide silver electroplating solution based on strong organic acids. This innovative technology eliminates cyanide use entirely, greatly enhancing worker safety and minimizing environmental impact.

Unlike conventional silver plating that risks damaging resist patterns or struggles with stainless steel surfaces, DAIN SILVER GPE supports direct plating on SUS materials and ensures clean processing over resist layouts, making it ideal for advanced electronic, precision, and medical applications.

The process is structured in two stages—strike silver plating and main silver plating—and can be adapted to both rack and continuous plating systems. Customers can choose from three types of surface finishes depending on their requirements: white matte, semi-gloss white, or glossy silver.
