Viscosity, color is not easy to give full play, poor reproducibility, color application Raoult's law and Gibbs free energy equation rational design;
There are certain guiding significance. A series of excellent colorant must have Ze dim. Based on two systems hydrophilic-lipophilic balance value (rattled walls), "double agent" adjusted HLB one of the two systems are incompatible main reason is usually added value, the balance, multiplied by the agent "leveled HLB value of the gap between its own polarity is induced effect.
Strong color, good fluidity, long-term storage without agglomeration, no precipitation, does not return to the thick, high solids content, viscosity stability, low foam, air drying, melting, and then frozen, not moldy where possible, low
VOC, batch color performance is poor.
