With the development of plastic decoration film, vacuum coating technology more and more application in the plastic products. Vacuum coating technology mainly include evaporation coating method and magnetron sputtering deposition method. Evaporation coating method are implemented by evaporation coating machines, magnetron sputtering deposition method is through the magnetron sputtering coating machine. In the coating process, vacuum coating coating plays an important role, the following, a brief introduction of the evaporation coating machine coating paint have? Evaporation coating machine coating often used coating can be divided into two categories: A, the traditional solvent-based coatings This is an early vacuum coating paint, mostly using heated baking method for curing. According to the matrix resin types can be divided into the following types of coating: 1, epoxy coating, This is the most rapid development in recent years of industrial coatings, epoxy coating has the advantage of strong adhesion, good corrosion resistance, good mechanical properties, the disadvantage is that weather is not good, adornment sex difference, surface gloss is not easy to maintain. So the epoxy coatings generally as a primer or paint. Vacuum coating, the use of the advantages of epoxy coatings, and other coating use, improve the comprehensive performance. 2, polyurethane coating This is one of the more common coatings, two-component polyurethane coatings and one-component polyurethane coating. Two-component polyurethane coating physicochemical performance good, solid content is higher. One-component polyurethane coating performance worse than two components. Polyurethane coating has the advantage of strong adhesion, hardness and flexibility, balance and wide adaptability of base material. So it is often used as primers and paint. 3, acrylic resin coating The coating has the advantage of light, good colour retention, strong weatherability, excellent adhesion. In addition to the above coating, there are many traditional coating, because of the existence of birth defects, hindered the development of traditional coating. Second, the uv curing coatings Uv-curable coatings with low energy, fast curing and film performance is good wait for an advantage, solve the defects of the traditional solvent-based coatings are widely used in the vacuum coating, gradually replaced the traditional coating. 1, polyurethane acrylates uv curing coatings The coating has the advantage of strong adhesion, corrosion resistance, abrasion resistance, flexibility, etc. 2, epoxy acrylates uv curing coatings The coating is mainly as auxiliary resin added to the paint, main effect is to increase the hardness, fast curing and good adhesion, etc.
What is the vacuum
Vacuum means that a given gas pressure within the space of less than the area of a standard atmospheric pressure gas state.
Vacuum is rarefied gas environment. Compared with the atmosphere it has a number of advantages, such as gas thin, less oxygen, clean environment...
