Uyemura International

At Uyemura, our lifework is the development, and continuous improvement of chemistries and equipment that enhance the productivity and profitability of our customers. We supply a broad range of high-performance products for the general metal finishing, automotive, health care, jewelry and connector industries, including:

• CL Satin Nickel Plating - one of the most versatile finishes ever developed, this electroplating process can produce parts consistently in several different finish appearances. By filtering one ingredient and replacing it with a second, or third, or various combinations, the grain structure is changed such that different matte nickel appearances can be plated. CL Satin Nickel plating has gained wide acceptance in the automotive and plumbing industries ? among other decorative usages. Uyemura introduced this important satin plating technology to the North American market. Today, we are the leading supplier of both satin nickel and electroless nickel processes. MORE
• CL Technologies' SN1 Tin-Nickel Process provides a bright, durable finish with a distinctive reddish layer that's ideal for decorative applications. Plating over bright nickel or satin nickel creates a distinctively warm appearance. MORE
• Nickstar Black Nickel is a decorative black nickel technology that deposits a thin, and highly uniform over-coat of black nickel-zinc alloy, preserving the substrate's brightness and producing an exceptionally rich black nickel finish. MORE
• NBB Electroless Nickel - this process is bright and robust, also free of lead and cadmium. It is a mid-phos electroless nickel process in the range of 6 to 8. MORE
• KTY Electroless Nickel - the world's first "heavy metal-free" electroless nickel. Lead, cadmium and other heavy metals traditionally used for adding brightness and stability have been eliminated. MORE
• ANP Electroless Nickel Plating for Aluminum - substantially improves plating onto aluminum. Plating electroless nickel on aluminum has been problematic and costly due to short bath life. A normal EN bath can plate steel for six to eight MTOs (36 - 48 g/l nickel plated). Plating onto aluminum reduces that bath life by about 50%. The typical failure is poor adhesion of the nickel to the aluminum, resulting in blisters or nickel peel when the aluminum is bent. MORE
• Miralloy - An electroplating alloy combination of tin, copper and zinc, is an excellent alternative to nickel for zippers, buttons and clasps. Miralloy is a high-quality, cost-effective finish that is inert and long-lasting. MORE
• Non Mist-L Plating Anti-mist for chromium platers. EPA-compliant. This new anti-mist additive forms a strong foam blanket that reduces the bath's surface tension, preventing the migration of dangerous mists. Non Mist L also conserves plating solutions by minimizing evaporative losses and drag-out. Chromic acid concentrations in the plating bath are kept low, and so is waste treatment. MORE
• Umicore Electrolytic Palladium for decorative and technical applications is a slightly alkaline palladium electrolyte that produces high-gloss, low-porosity, bendable coatings. Excellent corrosion resistance; stable electrolyte has a wide operating range of current density. Rack or barrel application; ideal for wire connectors, wire leads, automotive engine components and decorative parts, cabinet hardware, military equipment, printed circuit boards.
