Surface Treatment (Chemical Shop)
The core process that determines the quality of aircraft components everything about surface treatment.
The surface-treatment line of Korea Surface Treatment Co., Ltd.
is equipped with a large-scale chemical processing system based on fully automated and semi-automated equipment for
improving the corrosion resistance of aluminum components and maximizing paint adhesion.
With a range of pretreatment technologies, including eco-friendly processes,
we are enhancing the quality competitiveness of the domestic aerospace industry.
