White carbon black is now a very popular product. Because of its good performance, wide application and valuable potential functions, white carbon black has not been abandoned. The key is that the field of white carbon black is indeed too wide. Today, we will talk about the application of white carbon black in leather coatings.


The leather finishing agent is white carbon black, which has two types: high gloss (bright) and matte. Usually, the glossiness required is adjusted according to a certain proportion of bright and matte. Gas phase white carbon black is used as a matte finishing agent and plays a role of extinction. Because the deposited matte powder is more serious, it simply presents a deposition appearance in the polyurethane system. The extinction effect of Degussa vapor phase extinction powder ts-100, tt-600, or Japanese tokama fm-14 can be treated, but the cost is high. At this time, Wacker N20 (hydrophilic, 200 square meters / gram, uniform particle size of 12 nanometers, can achieve extinction and reduce costs together. N20 also plays a role in preventing sedimentation. More importantly, N20 will not reduce the brilliance and fullness. Wacker N20 has been widely used in the leather finishing industry. Leather finishing is mainly distributed in Jiangsu, Zhejiang, Fujian and other three provinces.
