Expanding from automotive paints into the adhesive industry.

In the 1930s, the majority of cars on Japanese roads were black-painted imports. Rock Paint successfully developed a high-quality black coating comparable to those of leading international manufacturers, driving significant sales growth. Today, the company manufactures and sells a wide range of coatings for various sectors, including automotive, architectural, industrial, and household use. Furthermore, leveraging the resin synthesis technology developed through decades of paint production, the company is also actively developing adhesives for lamination.

Upcycled coatings that inspire sustainable living.

Rock Paint is tackling environmental issues through upcycling, transforming waste into materials of new value. The company incorporates materials such as shells discarded from food processing, food scraps, and bamboo—whose overgrowth is a growing concern—into its coatings. By treating the resulting fibers and particles as “unique characteristics” and making the transformation process to light, Rock Paint creates a viable end-use for waste materials, proving that waste can be reborn as a desirable new product.
