Company information
Naruse Chemical has been walking alongside Japan's economic growth after the first oil shock, primarily in the manufacturing and supply of waterproof adhesives for construction, based on its independently invented "Atactic Polypropylene Water-based Emulsion" (Patent No. 925268). However, after the collapse of the bubble economy, Naruse Chemical is also facing a time of transformation amid the rapidly changing political and economic structure of Japan. We are now striving to respond to the diversifying needs not only in the construction sector but also in various fields such as marine, greening, and environmental issues, while aiming to transform into a high-tech company. We are confident that the existence value of "Technology of Naruse Chemical" lies in our ability to supply products that meet the demands of society and contribute to it.
