In recent years, functional films of polymer substrates have been more and more widely used in various fields, especially for films with optical functions. Polymer films (such as PET, PC, PMMA, PVC, TAC, etc.) have excellent optical and physical and mechanical properties. Through the implementation of additional functional coatings such as surface hardening coatings or some special functional coatings, the functional properties of these polymer films are improved and the application value is increased.
According to coating online understanding, radiation curing technology is the current rapid development of an industrial technology, the technology has entered a period of rapid development since the 1980s, more than 30 years has maintained rapid development. The application of radiation curing technology in film processing promotes the development of functional films. In recent years, the rapid development of some high-tech fields such as nanomaterials and coatings technology also makes the quality of functional films become higher and higher, and the varieties become richer and richer.
There are three purposes to implement functional coating on thin film surface: one is to give new functions to thin film; The second is to protect the film and improve its durability; Third, the film plays a decorative role.
In a word, the quality of thin films can be improved and the application range can be expanded by implementing functional coating on the surface of thin films. According to coating online understanding, the current manufacturing coating materials mainly concentrated in Japan, coating processing countries and regions are Japan, China Taiwan, South Korea.At present, functional membrane materials are mainly used to complete the coating in China, while the industrial system of coating processing in China is still under construction.
The key of functional film is to use functional coating on the film surface. The development direction of functional film is to use radiation curing coating technology to improve the abrasion resistance of the film while endowing it with various functions.With the development of science and technology, more and more kinds of functional coatings for film, different functions can give film more perfect use function and protective decoration effect, can greatly enrich the application range of these film materials.
