Development Trend and Application Prospect of Polyurethane Coating

Polyurethane coating occupies a very important position in the coating industry due to its excellent adhesion, friction resistance, high gloss and other excellent properties, favored by the market and consumers.

Polyurethane coatings are particularly outstanding in terms of color and gloss retention. They have excellent chemical resistance, excellent weather resistance, and physical and mechanical properties. The paint film has full color, good levelling property and DOI, as well as moderate flexibility and hardness. It is this durability of the polyurethane coating that makes it an ideal choice for demanding end markets. Bi-component polyurethane coatings are not only used in passenger cars, but also widely used in luxury cars.

The combination of polyurethane coating and epoxy primer can become a heavy-duty anticorrosion coating system, and its excellent comprehensive performance makes it widely used in anticorrosion engineering. Compared with other coatings, the polyurethane coating system has the lowest life cycle cost, and can meet the high emission standards for organic volatiles in Europe and the United States. Its excellent chemical properties, good economic benefits and low organic volatile standards have won more and more recognition from professionals and users. Polyurethane has been successfully used in bridges, offshore platforms, port machinery, factory equipment, storage tanks, pipelines, airports, stadiums and other construction facilities.

In the future, concerns on health and safety and the development of laws and regulations will continue to affect the polyurethane coatings market. As long as you compare the existing coating technology, it is not difficult to find that polyurethane chemistry with resin and isocyanate as the core can provide the best, the most economical and the most flexible solution.
