Dongkuk Steel, South Korea's metal construction material maker, has developed Luxteel Biomass Uniglass, the world's first solvent-free colored steel sheet.
The paint on color steel sheet consists of resin, solvent, and pigment, of which solvent accounts for about half.
The solvent is a petroleum-based raw material and is used to control the viscosity of paint. When manufacturing color steel sheet, it is heated and dried, and carbon dioxide is generated.
Dongkuk Steel succeeded in applying biomass paint without volatile solvents to color steel sheets for the first time in the world. Using biomass as a raw material to make a solvent-free resin is a key eco-friendly technology.

Dongkuk Steel reduced carbon emissions by more than 80% compared to the existing color steel sheet method by adding UV (ultraviolet ray) curing technology to solvent-free color steel sheet technology.
Dongkuk Steel plans to promote commercialization in the second half of this year through productivity verification and product development consultations with major customers in March of this year.
