Taiwan Institute of Technology successfully developed water-based PU resin

Polyurethane resin (abbreviated as PU) is widely used in the coating industry, but the free isocyanate groups are toxic to the human body, so the water-based potential is imperative. The Institute of Chemical Industry of Taiwan Industrial Science and Technology Co., Ltd. and Youxin Chemical spent 3 years to successfully develop intermediates with acid groups and sulfonic acid groups, thereby introducing a new generation of environmentally friendly water-based PU products. This research has broken the European and American standards. The company's monopoly on water-based PUs.
Clothes used in everyday life, sports shoes and purses, sofas, coatings on mobile phone housings, paints on CDR surfaces, wall paints, and plush fabrics for car interiors are all used for PUs. The PU resin has excellent functions. Taiwan's annual output is as high as 170,000 metric tons, and its annual global production exceeds 2.5 million metric tons. However, more than 90% of the current PU resin products contain a large amount of organic solvents, and these organic solvents cause serious environmental pollution when PU resins are used. Therefore, European and American countries have gradually banned the use of PU resins containing more toxic organic solvents.
The new products developed by the Institute of Chemical Industry are mainly using the key technology of water-based PU synthesis and acrylic compounding technology introduced by the Institute of Chemical Industry and Technology of ITRI. The manufacturing costs are significantly reduced, and the products are given higher water, weather, and chemical resistance and can be improved. The product's international competitiveness.
The person in charge of the institute pointed out that this project is an example of the successful combination of production, government, and research for the development of environmentally friendly new products. It uses the resources and support of the industry bureau's leading new product plan, combined with the long-term research and development of the Institute of Chemical Industry \"waterborne resin\" The established scientific foundation and technical reserves, coupled with the expertise of the partner companies in the Design of functional new products, have effectively solved the difficulties in the lack of resources for research and development of the synthetic resin industry with SMEs as the main body.
