Paint is a product that contributes environmental protection with a variety of functions such as protecting materials, giving aesthetic worth, thermal barrier, less polluting and maintaining these functions over long periods by several micrometer-thick coating. At present, most of paints are thermosetting type and the choice of curing reaction type is one of the significant elementary technologies. From the standpoint of the recent environmental protection movement, the paint manufacturing industries must respond to the issues of emission control of VOC and greenhouse gas such as CO2. As most of VOC and CO2 from paint are released in the drying process of coating, the improvement of this process is essential. For reduction of VOC in the drying process, conversion of the paint from solvent-based to waterborne and powdery is necessary. Meanwhile, the reacting system which harden at low temperatures in a short time is needed for reducing of CO2 . It is significant to choose the appropriate curing reaction to solve these issues. In this article, I will introduce two kinds of curing systems. One is used in waterborne and powdery coating and the other is ultraviolet curing system as a significant tool which harden at low temperatures in a short time.
