Business introduction

Fine chemicals business

Resulting from scientific advancement, numerous chemical products make convenient lifestyles and new industries possible. Also they have become indispensable to our lives and to industry. The highly functional and high value-added products called fine chemicals have the potential to dramatically change society.
In the 1970s, KOHJIN entered the chemical market applying our original synthesizing technologies. With a method of producing acrylamide derivatives as our core technology, we have been developing, producing, and selling monomers and polymers not offered by any other companies. Our water soluble monomers are highly regarded as environmentally friendly chemical products. Demand is growing at an especially strong rate for materials for ultraviolet curable coating agents, inks, and adhesives that do not generate volatile organic solvent deemed to contribute to sick building syndrome and other maladies.
We will continue our research and development efforts as we seek to supply products with higher levels of utility and safety.
