Waterborne Polyurethane Dispersions（PUDs）

Product Summary

Waterborne polyurethane dispersions (PUDs) are polyurethane polymer resins dispersed in water. They are widely used for environmentally friendly, low volatile organic compound (VOC) water-based paints, adhesives, ink binders, and coatings. UBE is a global supplier of polycarbonate diols (PCDs), a highly functional polyol used as a raw material for urethane, and delivers tough and durable resins comparable to solvent-based urethanes with PCD-derived features including excellent heat, chemical, water, and weather resistance.
The ETERNACOLL® UW series offers PUD grades suitable for an array of applications, including automotive interior and exterior paints, steel surface treatment, wood and floor coatings, plastic, film, and ink binders.
UBE is committed to complying with chemical regulations in Europe, North America, China, South Korea, Taiwan, and other countries around the world and to providing the most suitable solutions to meet our customers' needs.
