Founded in 1947, Kansai Catalyst has been in the business of functional materials development and manufacturing for over 60 years. Throughout these years, our highest priority has always been customer trust. Customer trust is essential for building a lasting relationships with customers, as well as for growing as a company.
As a chemical company, we have also been focusing on creating products that demand high purity and high quality and developing unique technologies to meet these demands. These technologies serve as a source of the strength that has allowed us to continue growing to this day. Currently, we provide products to be used as key materials in a broad spectrum of fields such as batteries, electronic components, catalysts, surface treatments, pigments, and reagents, earning high praise from our customers.

Of these fields, the demand—both quantitative and qualitative—for synthetic, high-purity battery materials is increasing rapidly along with the popularization of electric vehicles, hybrid vehicles, and other types of eco-friendly automobiles, and so are customer expectations toward Kansai Catalyst as a supplier of such materials. In anticipation of this trend, we have expanded and upgraded our facilities while refining our technologies, and this forward-looking stance has led to our achieving our current reputation. We will continue our efforts to take the right course of action by anticipating and meeting future needs as quickly as possible in order to be a company that by pioneering the future remains essential to society. We appreciate your continued support.
