With a total funding of HK$4.3 million, of which HK$1 million was sponsored by Hercules Tech Limited, a wholly owned subsidiary of the Hong Kong listed Yip's Chemical Holdings Limited, the project entitled Nanotechnology for advanced electrophoretic coating aims to achieve a low cost, long-life-span anti-corrosive coating for the industrial market. The application of electrophoretic coating is being widely used for the bathroom fittings, window and door, automotive components and accessories, toys, medals, coins and watches, bicycle parts, spectacle frames, trophies, household goods … etc.
The purposes of the research project are:
(1) to raise the nano technology for use in the production of high quality coating,
(2) to reduce the emission of toxic gases in the coating application process,
(3) to develop new capillary electrophoretic nano-particle sizing technology,
(4) to improve the quality of the existing nano coating products of Hercules Tech Ltd, and
(5) to replace the dangerous toxic coatings by non-toxic and environmentally friendly coatings.
The recent drive in concern of safety of workplace, health and environmental protection demands the replacement of organic-solvent based paints by water-based paints. The advancement in nanotechnology makes the replacement possible as the nanopaint prepared by nano-size polymer emulsion is able to produce a non-porous polymeric coating at an affordable cost with surfaces that are ultimately smooth, appealing with extremely good anti-corrosion characteristics.
The success of the recent marketing of nanopaint in China and Hong Kong in the fields of civil, marine and offshore engineering, refineries and building services applications, illustrates the huge potential for developing nanotechnology for the surface coating industry. The advanced electrophoretic coating using nanotechnology will lower the overall cost due to the reduction of the coating thickness and the prolonged anti-corrosion life span compared with the conventional electro-plating.
HKU will teamed up with experts from Tsingdao Ocean Chemical Institute, Changchun Institute of Applied Chemistry from Chinese Academy of Sciences, Hercules Tech Limited and Tru-Seal International (HK) Limited to develop two new electrophoretic technologies. The first one is developing capillary electrophoresis for sizing of nano-emulsion to secure the quality control and assurance in the production of nano material and the second is developing procedures for electrophoretic deposition of nano-polymer and composite coatings. This will diversify the use of nano emulsion in industrial applications.
HKU awarded Innovation & Technology Fund on Advanced Nano Surface Coating Technology
