大関化学工業 Company Profile

Protecting the environment gently for the Earth and responding to trust.

It has been over half a century since Paratex was born. During this time, Ozeki Chemical has responded to a wide range of waterproofing needs and has been engaged in the development of various products and methods. The Paratex waterproofing method utilizes a unique water-stopping mechanism and excels in comprehensive durability, including strong adhesion, water resistance, and chemical resistance. Its functionality and high quality have been proven even in experiments at large synchrotron radiation facilities (SPring-8). As the era increasingly demands a sustainable society, Ozeki Chemical, with its Paratex brand, leverages its past achievements and takes responsibility for its products. With the corporate philosophy of "protecting the environment and responding to trust," we are always committed to creating products that are friendly to the global environment and people's living conditions, continuously providing safety and security. Ozeki Chemical wishes to further expand the "trust" network of Paratex, develop various products, and be a company that can contribute even more to society.
