Description

technical field [0001] The invention relates to a coating, in particular to a novel low-temperature curing epoxy powder coating. Background technique [0002] Powder coating is a rapidly developing field in the entire coating technology, especially since the 21st century, because its VOC emission is almost zero, environmental protection requirements have driven its rapid development. However, general-purpose powder coatings have high curing temperatures, limiting them to coating substrates that can withstand high temperatures, such as metals. The development of powder coating systems that cure at low temperatures not only allows the coating of metal substrates but also opens up new areas of application, such as heat-sensitive wood or plastics. In recent years, due to the increasing demand for energy around the world, reducing energy consumption and protecting the environment have become the main body of enterprise development. In view of this, the development of low-tempera...
