TQ-500是表面经过有机处理的沉淀法二氧化硅消光粉，特别适用于厚涂型溶剂、水性涂料体系。TQ-500具有易分散、消光性好、增加滑性、悬浮性好等特性。和TQ-412一样应用于色漆中时，涂层的表面性能依然优越而且表面极度平滑。TQ-500适用于水性涂料，双组份聚氨酯涂料、木器漆、透明漆、烘烤型涂料、自干型涂料、UV涂料等行业。二氧化硅类消光粉易分散，可在生产过程中的任何阶段添加，应该用高速分散机分散，不能研磨，否则影响它的消光效率。如果使用TQ-412后引起干燥时间延长，可改用或添加TQ-500。其他条件不变，随着消光粉用量的增加，消光（哑光）增强。
TQ-500 is a precipitation silica matting powder with organically treated surface, especially suitable for thick coating solvent and water-based coating systems. TQ-500 has the characteristics of easy dispersion, good matting, increased slip, and good suspension. When used in the same paint as TQ-412, the surface performance of the coating is still excellent and the surface is extremely smooth. TQ-500 is suitable for water-based coatings, two-component polyurethane coatings, wood coatings, clear coatings, baking coatings, self-drying coatings, UV coatings and other industries. Silica-based matting powder is easy to disperse and can be added at any stage in the production process. It should be dispersed with a high-speed disperser and cannot be ground, otherwise its matting efficiency will be affected. If the drying time is prolonged after using TQ-412, TQ-500 can be used or added. Other conditions remain unchanged, with the increase of the amount of matting powder, the matting (matte) is enhanced.
