Automotive coatings, also known as the masterpiece of coating technology, provide corrosion resistance of steel panels that form the car body, protect the car with strong durability against the external environment such as UV rays, acidic rain, salinity, oiliness and chemicals, and beautify the overall appearance of the vehicle. Through a multi-layer structure consisting of electrodeposition, primer, base coat and clear coat, the film performance is increased and high quality is guaranteed.
Since the first application on a vehicle body in 1976, electrodeposition coatings (cation), also referred to as e-coats, have been applied to all vehicle bodies as a primer due to eco-friendly and economic properties.
The latest trends in e-coating technology include an expansion of lead-free electrodeposition in response to environmental regulations, development of low-bake (130-140℃) e-coat in response to the diversification of materials that form the vehicle body and development of high-weatherability electrodeposition and thin-film electrodeposition technologies. Currently, most of the electrodeposition lines in Korea have converted to lead-free type, which is applied to 90% of the global manufacturing system. KCC developed e-coats through technical partnership with Herberts-Vianova in 1984. In compliance with the top 5 heavy metals regulations set by the EU, KCC developed and applied a lead-free e-coat (ED2100) in 2000. Approximately five years later, KCC developed and applied high corrosion-resistant e-coats (ED3000HT/ECO1000) in response to the enhanced corrosion resistance quality of automobiles, and in 2012, by maximizing the interior applicability of e-coats, KCC successfully developed and applied ultra-high throw power e-coat (EC03000), which reduces the amount of consumption and secures stronger corrosion resistance.
