The surface of the hand model is protected by UV treatment. UV paint is ultraviolet curing paint, also known as photoinitiated paint. The UV high-gloss treatment will protect the surface, and a layer of smooth and transparent effect will be attached to the surface. Spray a layer of transparent oil on the surface of the sample and dry it with ultraviolet light. The product will be brighter and not easy to scratch. Advantages and disadvantages of hand model after UV : (1) High hardness. The highest hardness can reach 5~6H; (2) The curing speed is fast, the production efficiency is high, and it can be cured in 30 minutes by ultraviolet curing; (3) The coating performance is excellent, and the coating has excellent hardness, wear resistance, acid and alkali resistance, and Salt spray, resistance to gasoline and other solvents have very high performance indicators; especially its full paint film and outstanding gloss; (4) The photocuring process used in UV paint has no pollution when spraying paint, which is recognized as green Environmentally friendly products; (5) UV coatings are sensitive to dust, so they have strict requirements on the construction environment. (6) It is not sun-proof, and it is easy to crack under the sunlight. (7) It will turn yellow after a long time. Therefore, when the appearance of the product is required to be pure white, UV glazing is generally not used. (8) The price is relatively expensive, and the requirements for pre-coating treatment are very high.
