The high versatility of polyurethane coating technology offers many advantages over competing coating systems. Two-component polyurethane (2K PUR) coatings are seeing widespread use in application areas such as automotive, wind turbines, aerospace, and wood. However, there is constant pressure on formulators to further improve performance and reduce levels of volatile organic compounds (VOCs), in order to prolong life cycles and to improve sustainability. An effective way to achieve this is to add small amounts of four-functional polycaprolactones to a standard pigmented 2K PUR top coat. Critical properties can be adjusted by varying the amount of caprolactone polyol incorporated in existing ...
