UV vacuum plating, UV vacuum plating coating
The so-called UV vacuum plating coating is a kind of ultraviolet curing coating, which is developed on the basis of UV plastic coating. After the vacuum plating process, the product can not see the plastic products, in the packaging industry, car lights, watches and clocks. It is widely used in the manufacture of outer casings, mobile phone plastic cases, and the like.
UV vacuum plating in a vacuum environment, the vacuum chamber of the vacuum plating equipment is used to impart a high metallic luster effect on the surface of the plating part. The main components of the UV vacuum plating coating are color materials, photoinitiators, ultraviolet curing resins, leveling agents, and adhesion. Promoters, etc.
