The 'Dual sided Evolution' of White Carbon Black in the Coatings Industry: From Thickening to Functionalization
In architectural coatings, spherical white carbon black (particle size 100nm) increases the hardness of the paint film by 30% through physical filling, while reducing glossiness to below 5%, achieving a "matte effect". In the field of anti-corrosion, the white carbon black composite filler loaded with zinc phosphate can form a dense passivation layer, and the salt spray test life is extended from 500 hours to 3000 hours. In more cutting-edge applications, white carbon black doped with indium tin oxide (ITO) can increase near-infrared reflectivity to 85%, and can reduce building air conditioning energy consumption by 30% when used as a cooling coating.
