Core Technologies‐Precision synthesis technology
Precision synthesis technology
derived from coal chemicals
Making fertilizer from exhaust gas produced as a byproduct of the coal business was our starting point. Since then, we have honed our precision synthesis technology in the course of creating various products.

Many products that have led to the resolution of social issues have been created through the application of various technologies derived from precision synthesis technology.
Coating Agents
CHEMIPEARL™
Aqueous dispersion of polyolefin.
It is environmentally friendly product since it does not contain surfactants or organic solvents. It is widely used as heat seal coating, additive for water-based inks, anti-blocking agent, etc.
Material for Eyeglass Renses
MR™
Made from a unique material called thiourethane resin, MR™ achieves a good balance of properties, such as clarity, safety, durability, and refractive index. It is currently used in eyeglass lenses around the world.
Urethane Resins for Coatings
TAKELAC™ W/WS/WPB (PUD)
A water-based urethane resin made by dispersing polyurethane in water.
PUD can have a variety of characteristics, from soft & highly stretchable binders to extremely hard top coatings. It is used in a wide range of applications, including inks, packaging materials, and textile processing, helping to reduce environmental impact.
Polyurethane Raw Materials
STABiO™
The world's first plant-derived polyisocyanate curing agent for polyurethane coatings and adhesives with high functionality. Its high reactivity enables shorter curing time and contributes to energy conservation.
* Received the Minister of Economy, Trade and Industry Award at the 22nd Green Sustainable Chemistry Awards(2023).
