UV curing technology (UV Curing) uses ultraviolet light irradiation, can instantly curing resin, and its wide range of applications, can be used for immediate drying, curing inks, binders, coatings, etc. According to the latest market forecasts, the market will continue to grow from 2017 to 2025 due to the high quality and consistency requirements of modern industry.

UV curing generally uses long wavelengths, and if high energy, the surface of the binder curing will use short wavelengths. Its advantages include low temperature, low energy consumption and rapid treatment, UV curing does not produce high heat, irradiated object temperature does not rise can also complete the curing and drying operations; traditional thermal curing takes more than a few hours of engineering, but UV curing can be completed in only a few seconds, greatly reducing waiting time.

There are two types of resin photofixing materials: free radical systems and cationic systems. In the past, the market mainstream was free radical systems. However, this type of photofixing materials would have the problem of oxygen inhibiting curing, so it is easy to appear that the bottom of the material has been cured, but the surface is still wet and sticky.

In recent years, cationic materials have developed rapidly. It can not only improve the tightness, but also solidify the film, which can be blocked by oxygen free operation. It makes up for the shortcomings of free radicals and is expected to expand the market of photo and solid materials.

UV curing can be used in automotive, electronic products, communications, image art and other fields. In 2016, the U. S. UV curing market accounted for the largest market in North America, mainly driven by the demand for electric vehicles. According to market research, Tesla sells nearly 6500 electric vehicles in the United States every month.

UV curing technology has been applied to the automotive industry for a long time, including car body or headlight lens. Tesla also introduced its own UV curing technology, increasing the exposure area to one square meter, effectively reducing energy consumption by 83%.
