The Metals Industry Research and Development Center (DOST-MIRDC) recently developed a non-toxic electroplating process. The old process employs the use of cyanide, a chemical compound known to be poisonous to humans, animals and the environment. It is used, however, to harden metals that are electroplated or coated like gold jewelry. Health and environmental hazards inherent to the process prompted MIRDC to develop a non-cyanide gold electroplating solution. MIRDC registered the technology for patent which was granted by the Bureau of Patents of the Intellectual Property Philippines of the Department of Trade and Industry (DTI).
The solution can be applied to provide a metallic finish on different kinds of conductive materials (metals). It has various applications in the jewelry, furniture, automobile, and metalworking industries, among others. In addition, the cost of chemicals needed for the non-cyanide gold plating bath is 17 percent cheaper than the cyanide gold. Likewise, the non-cyanide gold plating process employs simpler waste treatment process and is 80 percent lower in waste treatment costs. ?(MIRDC\ AMGuevarra\ DOST IV-A S&T Media Service)
