Hinoact
Polymeric dispersants are used in the production of pigment dispersions in the electronics field, printing inks, paints, colorants, plastic products, etc., by adsorbing to the surface of ceramic particles and pigments to prevent re-agglomeration of the particles. The effects of adding polymeric dispersants are expected to increase the solid concentration of the dispersion, improve productivity, decrease viscosity, and improve stability over time.

Flow Reaction Catalysts
We have developed a new precious metal catalyst with low pressure loss for flow reaction by utilizing our technology and experience in hydrogenation reaction and catalyst preparation. These catalysts are made by loading precious metals such as palladium and platinum onto particle-size-adjusted charcoal or spherical activated carbon, and are effective for all hydrogenation reactions as well as conventional powder catalysts used in batch reactions.
Metals Recycling
Palladium and Platinum, the raw materials of precious metal catalysts, are extremely expensive. We recover only the precious metal components from used catalysts entrusted to us by our customers, and either purchase them for a fee or recycle them as raw materials for catalysts.
