Product Info

High-hardness, high-heat-resistant silver plating solution ideal for EV and electronic components. Achieves a uniform glossy appearance with an environmentally friendly non-cyanide formulation, provided by DAIWA FINE CHEMICALS (THAILAND) CO., LTD. in Thailand.

‘Dine Silver HKR’ is a non-cyanide, alkaline type bright silver plating solution developed in response to recent demands for electronic and EV (electric vehicle) components. It offers high hardness and heat resistance, suppressing discoloration of the film due to copper diffusion during heat treatment. Additionally, it complies with RoHS directives and does not contain any of the latest 22nd SVHC candidate substances, ensuring thorough environmental considerations. In Thailand, it serves as an optimal solution for rust prevention and protection of electronic and EV-related components.

■ Features
- High heat resistance: Suppresses film discoloration due to copper diffusion during heat treatment compared to conventional non-cyanide bright silver plating solutions (according to internal research).
- High hardness with a uniform glossy appearance: Vickers hardness of approximately 110 Hv, achieving both wear resistance and a glossy appearance.
- Environmentally friendly: Compliant with RoHS directives and free of the latest 22nd SVHC candidate substances, providing a low-environmental-impact, safe formulation.
- Broad applicability: Requires pre-treatment with various strike silver plating, suitable for EV components and precision electronic components.
