与水性涂料相比，紫外光固化涂料很难消光。消光能力取决于配方的本性、树脂的反应性以及固化的条件。通常，低的反应性和慢的固化条件有利于消光，高反应固化系统难以消光。绝大部分紫外光固化涂料体系对消光剂要求均不应影响其体系粘度，因此二氧化硅的吸油量要尽可能地小。这种消光剂的制造工艺有别于传统意义上的二氧化硅消光剂。同时，吸油量较小的消光剂往往堆比重较大，易沉淀，须经特殊处理才可使用。
Compared with water-based coatings, UV curable coatings are difficult to extinction. The extinction ability depends on the nature of the formula, the reactivity of the resin and the curing conditions. Generally, low reactivity and slow curing conditions are favorable to extinction, while high reactive curing system is difficult to extinction. Most UV curing coating systems should not affect the viscosity of the system, so the oil absorption of silica should be as small as possible. The manufacturing process of this matting agent is different from that of silica matting agent in the traditional sense. At the same time, the matting agent with a small oil absorption often has a large pile proportion and is easy to precipitate, so it can only be used after special treatment.
不饱和聚酯类紫外光固化涂料的消光相对较容易，与传统的消光剂机理相同。丙烯酸类的紫外光固化涂料与传统的涂料体系相反，往往有机物处理以及小粒径消光剂有较好的消光效果。涂料配方中如存在可能加速表面固化的组分时，较难消光。
The mechanism of UV curing coatings is the same as that of traditional UV curing coatings. In contrast to the traditional UV curable coatings, the UV curable acrylic coatings are often treated with organic compounds and small particle size matting agents. If there are some components in the coating formula that may accelerate the surface curing, it is difficult to extinction.
