“Nickel Sulfamate”

A High-Quality Surface Treatment Agent Nickel Sulfamate
-Enabling high-performance plating in diverse applications-

For many years, Nihon Kagaku Sangyo Co., Ltd. (President: YANAGISAWA Eiji) has been meeting the needs for surface treatment in diverse applications such as electronic components, plastic molding, and electroforming. In particular, nickel sulfamate for functional plating—which is based on our core technology and allows one to exercise a high degree of control over the plating layer in terms of precision, hardness, internal stress, etc.—is trusted by many of our customers, both domestic and overseas.
As information technology proliferates, electronic components are becoming even more densely packed and highly integrated, and this has in turn led to even greater demands being placed on the performance of surface treatment agents. By leveraging the know-how in surface treatment we have accumulated over many years, we supply nickel sulfamate products, as well as various sulfamate salts and additives, which satisfy such demands.

【What is nickel sulfamate plating?】

Owing to its corrosion resistance, nickel is widely used in surface treatment of metal products. Nickel electroplating baths include “Watts bath,”, which uses nickel sulfate, and “Sulfamic acid bath,” which uses nickel sulfamate, an ionic compound of sulfamic acid and nickel. Compared to Watts bath, sulfamic acid bath allows a finer plating, and is suited to application in modern electronic components and precision instruments.
Furthermore, depending on the combination of additives used, sulfamic acid bath can also be used to control the physical properties of the plating layer, or to lower the environmental impact of electroplating, and consequently, there is an increasing demand for it in a broad range of industries.

【Stable supply and technical support backed by domestic production】

We develop and produce nickel sulfamate and other superior surface treatment agents within Japan, primarily at our R&D Center and Saitama Plant, thus ensuring the stable supply of our products and provision of attentive technical support, in conjunction with our other domestic sites.
This allows us to meet a diverse range of surface treatment needs, and to offer solutions for a broad range of materials and shapes. Please do not hesitate to contact us with your inquiries.
