Dispersant is a surfactant that has two opposite properties: lipophilic and hydrophilic in the molecule. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids. It can also prevent the sedimentation and agglomeration of particles and form amphiphilic reagents required for stable suspensions. The function of the dispersant is to use a wetting and dispersing agent to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of the pigment particles, and adjust the mobility of the pigment particles. Sanfan mainly provides water-based ink dispersants, water-based paint dispersants, ceramic inkjet wetting and dispersing agents, architectural coating wetting and dispersing agents, etc.
