Most of the dispersants on the market are mainly amphoteric compounds, typical of surfactants, their molecular structure on one end of one or more with different pigments can form a solid chemical adsorption of active groups; the other end By the long chain of the resin composition. They can uniformly disperse the pigment particles which are not dissolved in the liquid and prevent the sedimentation and aggregation of the particles so that the pigment particles can form a stable suspension in the liquid phase. Capatue (TM) wetting and dispersing agent is a surfactant different from the traditional type of wetting and dispersing agents, organic functional layer monomolecular film can be formed on the surface of various substrates, it can be a plurality of anchor group respectively The filler and the resin are chemically bonded or physically bonded to improve both the compatibility and the binding force of the filler and the resin, which is different from the action principle of the ordinary surfactant based wetting and dispersing agent which only changes the hydrophiliclipophilic value of the surface of the material Unique performance advantages.
