Hydrophobic Fumed Silica Powder For Coatings and Inks 

Characteristics QX-120 is a hydrophobic fumed silica after treated with DDS(Di-methyl based on a hydrophobic fume silica with a specific  surface area of 170 m2/g. It is a kind of high purity white colloidal powder. Silica matting agents are commonly used in various industries to create a matte appearance in coatings, paints, inks, and  other applications. Hydrophobic fumed silica is a type of silica that has been treated to be water-repellent or hydrophobic.  This hydrophobicity helps to improve the performance of the matting agent in certain applications. When using hydrophobic fumed silica as a matting agent, it is important to consider the following factors: 1. Particle Size: The particle size of the hydrophobic fumed silica should be chosen based on the desired level of matting effect.  Smaller particle sizes generally provide a higher degree of matting, while larger particles may offer a softer matte appearance. 2.
