Ultraviolet light curing coatings referred to as UV curing coatings, the use of irradiation curing technology and the generation of environmentally friendly coatings, under the irradiation of ultraviolet light, can be crosslinked in a short period of time curing, the formation of a good coating film. Compared with traditional solvent-based coatings, UV-cured coatings have good application prospects because they emit less organic volatile components and are more environmentally friendly and energy efficient.
UV curing coatings are different from the liquid coatings we know, which are solvent-free and environmentally friendly coatings with good energy saving effect, simple process and other characteristics, and have good application effect in the coating process of metal devices. As the processing temperature of thermosetting powder coatings is relatively high, the coating curing time is long, in the process of melting, it is easy to occur orange peel phenomenon, which seriously affects the surface quality of the coating.
Through the study of the composition and application of UV curing coatings, can ensure that the storage stability of UV curing coatings to get a better enhancement, to make up for the shortcomings of thermosetting powder coatings, such as UV curing coatings melt temperature between 100 ℃ and 140 ℃, compared to thermosetting powder coatings, UV curing coatings melt temperature to be low, coupled with its curing speed is relatively fast in the alloy of heat-sensitive materials and heat-sensitive substrate parts such as The coating has achieved good results in the application of alloy heat-sensitive materials and heat-sensitive substrates.
In addition, compared to UV-curable liquid coatings, the raw materials in UV-curable coatings are mainly high-analysis quality resins, reducing the influence of reactive diluents on the quality of the coating, and its shrinkage rate is particularly low, which further improves the adhesion of the coating to the substrate. By applying UV-curable coatings once, a thick film of superior quality can be formed, effectively reducing the tedious process of multiple coats.
By analysing the composition of UV curing coatings, it can effectively reduce ecological pollution, help the relevant staff to better master the UV curing coating coating process, save coating coating time, with good ecological advantages and economic benefits.
