SEOUL -- Dongkuk Steel Mill, a metal construction material maker in South Korea, has unveiled a new colored steel sheet product by applying biomass paint without any volatile solvent. The company will promote commercialization in the second half of 2022.

The paint on color-coated steel sheets consists of resin, solvent and pigment. The solvent used to control the viscosity of the paint generates carbon dioxide while being heated and dried. Dongkuk has developed a solvent-free color steel product called "Luxteel Biomass Uniglass."

Dongkuk said that ultraviolet coating technology was applied together to reduce carbon emissions by more than 80 percent compared to the existing color steel sheet method. The solvent-free product can be applied to home appliances, elevators and walls.

"In the future, eco-friendly will be the main competitive edge in the colored steel sheet market." "We will focus on developing eco-friendly colored steel sheets through low-carbon processes and product research," an unnamed Dongkuk official said in a statement on March 7. Dongkuk has made sustained investments in colored steel to increase its market share.
