Toyoda Gosei Co., Ltd. has developed the world’s first* “lacquer black plating” technology for plastics. This new technology adds a jet-black color to the metallic brilliance of plating.

Lacquer black plating increases darkness of the color sensation by 30%

Up to now this effect has been achieved with the use of a clear smoke coating applied after the plating process. This had disadvantages, however: the clear coating deteriorates over time, decreasing the shine, and it could be chipped or damaged by flying gravel. For the new process, Toyoda Gosei took advantage of its materials technology to develop a novel plating system. The result is the new lacquer black plating, which increases the darkness of the color sensation by about 30% compared with the existing dark plating (difference in the L-value, an indicator of color brightness).

Growing demand for black plating

Toyoda Gosei’s existing plastic plating variations include chrome-like neutral plating, aluminum-like satin plating and dark plating. These variations satisfy a wide range of design needs, but the growing demand for black plating to meet the needs of increasingly popular sporty vehicle design led the company to develop lacquer black plating. Lacquer black plating will first be used on the radiator grille of the Lexus RC F. It is set to be used on products from other manufacturers as well.
