SK Kaken Co., Ltd. was founded as Shikoku Kagaku Kenkyusho in 1955, aiming to create something useful for the society. Since then, we have committed ourselves to the development of new technology, new products, and new market demand. In 2015, the company is celebrating the 60th anniversary of its foundation. The company started the business by recycling solvent (purifying hazardous waste solvent by distillation and changing into a new solvent ) and developing water-based architectural coating. We changed the company name to Shikoku Kaken Kogyo Co., Ltd. We developed sand-wall-like coatings and ceramic tile-like coatings by using inexhaustible ceramics as well as spray tile coatings that shortened a work period. Thus, we kept developing new materials to meet the market demand of the time.
