After discovering fundamental defects in conventional manufacturing processes, we invented a revolutionary carbon disulfide manufacturing technology. We established the manufacturing technology “SK type electric furnace process,” which solved many problems.
We were the first in Japan to develop the “anhydrous sodium sulfate manufacturing process,” based on the “vacuum evaporation process.” Though the goal was deemed next to impossible, we nevertheless succeeded in the continuous production of anhydrous sodium sulfate.
We were the first in Japan to invent the “hydrophilous continuous process,” which is an effective means of producing CMC (carboxymethyl cellulose). CMC was later developed into interior materials that established the foundation of our Housing materials operations.
We produced isocyanuric acid with our original manufacturing process, “tin bath method”. Using isocyanuric acid as a raw material, we were the first in Japan to produce chlorinate isocyanuric acid.
We developed “THEIC” through research into derivatives applying the various characteristics of isocyanuric acid.
We started research into an imidazole compound manufacturing process, and were the first in Japan to succeed in commercializing imidazole compounds. Later, it became the foundation of Fine chemicals operations.
We discovered that imidazole has a distinguished effect of preventing oxidation in copper and copper alloys, and applied for a patent. Using this imidazole compound, we developed OSP called “Glicoat” for protection of the surfaces of PWBs.
We made inroads into the interior finishes market as part of the expansion of applications of CMC. We also invented our original “granulation technology” and developed an authentic industrial product for Juraku walls called “JULUX.”
We promoted applied research into products that matched customer’s needs, including insulating materials, sealing agents, and adhesives using imidazole, as well as diverse epoxy resin compounds.
We established a system for producing the insoluble sulfur “Mu-Cron,” which is a rubber vulcanizing agent for steel radial tires, by utilizing the knowledge concerning carbon disulfide.
We developed a Microbiological / Enzymatic agent called “HIPOLKA,” which is characterized by a high wastewater-treatment capability, through joint research with a US company.
We were the first in the world to succeed in the synthesis of aluminum borate whisker. It drew attention as a new, high-function, high-quality material and was used as a reinforcing agent for a wide variety of materials such as resins, metals, and ceramics.
We were the first in the exterior products industry to acquire the “G-Mark” (current “Good Design Award”) for our accordion gate, called “Rubicon Type 11.”
We developed the heat-resistant Type OSP “Glicoat-SMD,” which combines the heat resistance required of double-sided PWBs to bear with several applications of soldering, by putting our imidazole synthesis technology to full use.
We constructed the Research Center in Utazu-cho, Kagawa Prefecture, as the stronghold of our R&D activities.
We developed the diatomaceous earth wall material “Keiso-Kabe,” which has a humidity-control function and a formaldehyde-adsorption and formaldehyde-decomposition function, which together provide rooms with a healthier, more comfortable indoor environment.
We developed the “Garbage Stocker”, which contributes to a beautiful living environment.
We developed advanced & specialty Chemicals capable of providing resins with a higher function by making the most of our organic synthesis technology, which we accumulated from the synthesis of imidazole and isocyanuric acid.
We developed a Chemical Adhesion Process called “GliCAP”, which selectively forms organic films on the copper surfaces of PWBs to improve adhesion between copper and resin effectively.
We developed the “Keiso Reform”, which is applicable directly over wallpaper.
We developed “Green Shade”, which is capable of storing rainwater for natural irrigation.
We developed “My Port”, which has a unique design and high functionality.
We developed an aluminum system fence called “Art Wall,” which combines safety and workability with innovative design.
