Electroplating is the process of using an electrical direct current to coat an electrically conductive object with a thin layer of metal. EPi offers a variety of high-quality electroplating processes that are ideal for all types of metal finishers. Learn More
Black oxide finishes offer dimensional stability, eye-appealing appearances, retention of surface properties, and corrosion resistance when sealed with an oil, wax, or lacquer. Learn More
Antiquing, oxidizing, and patining are processes that chemically "age" or "weather" metal, resulting in a variety of colors, finishes, and effects. Learn More
Every year, rust costs metal-finishers millions of dollars. Water-displacing oils, water-soluble oils, waxes, lacquers, and temporary rust inhibitors can enhance the quality of a metal finish or protect bare steel parts. Rust preventatives offer stain, humidity, and salt spray resistance. Learn More
All metals need to be cleaned prior to electroplating, blackening, or finishing. Metalworking fluids and carbonaceous smut need to be removed in a soak, spray, electroclean, or ultrasonic cleaning. A properly cleaned part will have excellent adhesion and be brighter, blacker, and smut-free. Learn More
EPi offers high-quality chromates and passivates for a variety of metals. Pass salt spray tests with aesthetically pleasing parts that have superior white/red corrosion resistance. Learn More
Dry-powdered and liquid acid salts are specifically formulated for removing rust, scale oxides, stains, and smut from a variety of metal surfaces. Acid salts are also used to activate metal surfaces for further finishing. Learn More
EPi's series of stabilized peroxide bright-dip processes prevent re-tarnishing of brass, leaded brass, and copper after brightening. Chemically polish stainless steel alloys that contain nickel with a formula containing a blend of mineral acids. Learn More
E-Preps are used for one of the most critical steps in the finishing process: preparing your metal parts for successful plating or blackening applications. Learn More
Metal-stripping processes help remove copper, nickel, zinc, or tin from steel surfaces. Learn More
Iron, manganese, and zinc phosphate finishes provide extensive corrosion protection and prepare surfaces for a strong paint bond. Learn More
Powerful corrosion-resistant sealers with exceptional salt spray protection are used over zinc-plated passivations. Learn More
EPi's waste-treatment processes can help reduce overall waste disposal costs and be gentler on the environment. Learn More
Products that accommodate brush plating for localized plating or plating of an item that cannot be tank-plated. Learn More
Cyanide-free processes that eliminate the need to report to the Department of Homeland Security, saving time and money. Learn More
Since 1954, EPi has been an innovator in the development and manufacture of electroplating, black oxide, antiquing, rust preventative, and metalworking products for global companies and hobbyists alike.
