Recently, Yelechem announced the successful development of an environmentally friendly waterborne polyurethane resin with high gloss and ultra-high hardness, marking a major breakthrough in the field of high-performance applications of waterborne polyurethane materials. While maintaining excellent environmental performance, the product's gloss, hardness and scratch resistance have reached the industry's leading level. It can be widely used in high-end wood coatings, automotive repair paints, 3C electronic product coatings and industrial protection, providing a new solution for green high-performance coatings.

Technological breakthrough: taking into account both environmental protection and performance
Traditional waterborne polyurethane resins are often difficult to match solvent-based products in hardness and gloss, which limits their application in the high-end market. Through precise molecular structure design and nano-composite modification technology, the R&D team of XX Company has successfully improved the cross-linking density and surface flatness of the resin, making its hardness reach more than 3H (pencil hardness) and gloss (60°) more than 95GU, while also having excellent chemical resistance and impact resistance. In addition, the resin adopts a solvent-free water-based system, and the VOC content is far lower than the national standard, which meets the requirements of global environmental regulations.

Broad application prospects promote industry upgrading
The launch of this high-gloss and high-hardness waterborne polyurethane resin will effectively solve the environmental pollution problem of traditional solvent-based resins, while meeting the high-performance requirements of the high-end market for coating materials. For example, in the field of high-end furniture, it can replace traditional PU paint to provide more environmentally friendly and durable surface protection; in the automotive repair paint market, its high gloss and fast curing characteristics can significantly improve construction efficiency; in the coating of electronic product shells, its excellent wear resistance and anti-fingerprint performance can greatly improve product quality.

The industrialization process is accelerated to help green manufacturing
At present, the product has completed laboratory verification and pilot production, and is expected to achieve large-scale mass production in 2025. Yelechem said that it will continue to optimize product performance in the future, and expand its application in emerging fields such as new energy and aerospace, promote the innovative development of waterborne polyurethane technology, and help the global green and low-carbon transformation.

The successful research and development of this high-gloss and high-hardness waterborne polyurethane resin not only fills the gap in domestic high-end waterborne coatings, but also provides a new technical direction for the development of global environmentally friendly coating materials.
