HDI derivatives are advanced functional polyurethanes widely used as paint hardeners and are integral products in the company’s Specialty business portfolio. They are valued for their superb resistance to yellowing and weathering, which makes them essential as high-performance hardeners in automotive and architectural exterior coatings.

Tosoh’s expansion of its production capacity for HDI derivatives responds to the robust growth of the global coatings market, propelled by steady demand in developed economies, increasing demand in emerging markets amid heightened motorization, and rising demand in worldwide markets amid elevated infrastructure investments. Industry projections indicate growing demand for HDI derivatives.

The increase to HDI derivatives production capacity is thus a strategic move by Tosoh to position itself to capitalize on growing demand for and to ensure the stable supply of HDI derivatives. The company intends to significantly expand the scale of its business in HDI derivatives to increase corporate profitability. Tosoh, meanwhile, is committed to meeting the evolving needs of its customers and thus contributes to advancements in coating technologies for diverse industries.
