Prospect of waterborne polyurethane coatings

Prospect of waterborne polyurethane coatings

After decades of development abroad, waterborne polyurethane products have approached or reached the level of solvent-based products in automotive coatings, leather finishing agents, adhesives and other fields. The future development trend is to increase the added value of products, develop advanced technology, and open up new fields of application.At present, there is no real competitive professional waterborne coating manufacturers in China, the core technology of waterborne polyurethane resin synthesis is not up to standard, the product quality is unstable, the performance is generally not high, and the production scale is small.The main reason lies in the lack of professional technical personnel and continuous complete sets of production equipment for the production of waterborne polyurethane.This is also one of the reasons for the poor appearance of waterborne polyurethane products in the market.

The price of chemical raw materials skyrocketed, so that many coating enterprises face a survival crisis, cost reduction has become a more critical issue, no time to take into account the new environmental protection technology, to some extent, hindered the development of waterborne polyurethane.In addition, in the domestic water-based coating has not been to the great development period, water-based coating products market has not been fully opened.In China's current market, the competition in the water-based coating market is only the ornament of the competition between solvent based coatings, because many coating manufacturers are mainly based on solvent based coatings.

As the decisions of large paint manufacturers affect the trend of the whole market, the market demand for waterborne polyurethane is not large.

At present, the development direction of waterborne polyurethane technology in China should focus on the following aspects: to improve the mechanical properties, solid content and bonding strength of waterborne polyurethane materials, especially the initial bonding strength;On the basis of further reducing V0C, the research on the crosslinking mechanism of waterborne polyurethane and the development of new crosslinking agents were carried out to improve the curing properties of waterborne polyurethane at room temperature.Minimize the amount of organic solvents, and eventually achieve no solvent;Solve the problem of poor fullness and low gloss of waterborne polyurethane coating film, develop high-performance coating, and actively explore new application fields;By further reducing the cost of waterborne polyurethane, the application problems of waterborne polyurethane technology were solved.Strengthening the basic theory research related to waterborne polyurethane materials;Carry out construction technology research to reduce the influence of environmental temperature and humidity on the appearance of waterborne polyurethane coating film;Strengthen the research and development of waterborne polyurethane special equipment.

With the increasing awareness of environmental protection, waterborne polyurethane with good environmental performance has provided a broad market space, and waterborne polyurethane will undoubtedly remain a hot spot in the future.
