Research shows that the comprehensive performance of polyurethane acrylate coating is the best.\r\n\r\n2. Improved UV curing coatings\r\nOrdinary UV curing coatings mainly unsaturated polyester, polyurethane acrylate and epoxy acrylate as the main zwitterionic polymers, and then add the appropriate amount of active diluents and photoinitiators, in order to ensure that UV curing coatings to get a wider range of applications, the relevant researchers developed UV nanocuring coatings and UV curing silicone coatings and so on. Among them, the interface effect and volume effect of UV nano-curable coatings are more obvious, which has become a hot spot of research in the past few years.\r\nSiO2 particles into the UV curing epoxy acrylate coatings, can effectively improve the curing rate of the coating film, to ensure that the hardness and thermal stability of the coating film has been comprehensively improved, but the coating is very easy to particle dispersion phenomenon, the relevant researchers in order to better solve the problem, in the nano-coating by adding a certain amount of TiCL4 and triethanolamine, which effectively prolongs the coating of the chalking resistance. Time.\r\nUV-cured silicone coatings have good high temperature resistance and electrical insulation properties, in the field of electricity and printing to get a better application, in order to ensure that the UV-cured silicone coatings are efficiently applied, the relevant researchers often cross-linking silicone molecules for curing, so that the silicone molecules to form a more stable mesh structure, reduce environmental pollution.\r\n\r\n3.UV Curing Powder Coating\r\nUV curing powder coatings is a common powder coatings and UV curing technology combined with the new technology, UV curing powder coatings in the melting process, the resin will not occur curing, so that the coating levelling and bubble removal operation can be carried out smoothly, to prevent the heat curing powder coatings appear orange peel phenomenon. UV curing technology can ensure that the coating heating and curing temperature is better reduced, not only can improve the production efficiency, but also effectively save the amount of energy use, for UV curing powder coatings to open up a broader application space.\r\nIn order to ensure that the UV-cured powder coatings impact resistance to get better, the relevant researchers in the polyester molecular chain to introduce a section of the softer molecular chain, the formation of amorphous and semi-crystalline unsaturated ester resins of two different structures, which is applied to the UV-cured powder coatings vegetation, can effectively improve the film’s positive impact strength and anti-impact strength, and effectively shorten the curing time of the coating.\r\nCombined with a large number of research data show that the key to affect the solvent resistance and adhesion of UV-curable powder coatings is the degree of curing, through reasonable control of the solvent resistance of the coating, can ensure that the degree of curing of the coating reaches 99%. The addition of quantitative modified and unmodified hyperbranched resin in UV-curable powder coatings can ensure that the glass transition temperature of the resin system continues to decline from the original 47.21 \u2103 to 42.97 \u2103.\r\n\r\n \r\n
