Development trend of radiation curing coating industry

  The mercury lamps currently used in the UV-curing industry suffer from bottlenecks such as short operating life, potential mercury contamination, insufficient electro-optical energy conversion efficiency, severe heat generation, and unstable UV light output. UV LEDs, as a new light source, significantly overcome these shortcomings, making them a popular choice for UV-curing coatings.

  Waterborne UV-curable resins, combined with monomers, photoinitiators, and additives, can be used to create waterborne UV-curable coatings. Compared to traditional UV coatings, waterborne UV systems have higher resin molecular weights, minimal residual small molecules after curing, and higher coating safety and hygiene. If the amount of cosolvent in waterborne UV coatings can be effectively reduced and their overall performance improved, they could become a valuable complement to traditional radiation-curable coating systems.

  Electron beam curing coatings have outstanding advantages in weather resistance, coating strength and safety due to their features such as no need for photoinitiators, high crosslinking density and low residual monomers. The recent decline in the price of curing equipment will be conducive to the development of electron beam curing coatings. Whether used alone or in conjunction with UV curing coatings, it will provide the industry with more and better radiation curing coating solutions.

  Dual-cure technologies based on radiation curing can effectively address the high shrinkage stress and incomplete curing issues of traditional radiation-curing coatings. They can also, to a certain extent, address the dark area curing problem of radiation-curing coatings. These technologies, including light-heat and light-moisture dual-cure coatings, will help expand the application range of radiation-curing coatings and improve coating performance.

  UV-curable coatings are widely used in the coatings industry due to their high reactivity, fast curing speed, long life, low-temperature processing, zero VOC, high hardness, and abrasion resistance. UV curing technology is used in industrial finishing applications such as wood coatings, automotive coatings, wire coatings, packaging coatings, decorative metal coatings, and floor coatings. Demand for UV-curable coatings is expected to be high in the automotive sector, where these types of coatings are suitable for automotive finishing. Stringent environmental regulations have led to a decline in the use of conventional coating processes, which is also driving the global UV-curable coatings market.
