[0002] The main component of UV-curable coatings is a resin that is responsive to UV light. After being applied to the surface of the object, UV-curable coatings are irradiated with UV light, and the double bonds in the resin are photopolymerized by the photoinitiator, thereby rapidly curing and hardening. This type of coating has a fast curing time, excellent physical properties and chemical resistance, and is widely used in various surface coating, printing and other coating processes.

[0003] In order to ensure uniform mixing and stability of the paint, it is usually necessary to use a stirring device to stir the paint. By stirring, the various components in the paint can be fully mixed to ensure the quality of the paint.
