Adding method and processing guidance

In order to obtain good performance, additives must be added to the grinding material first, and then the pigment. Pre mix the resin and solvent components in the abrasive, and then slowly add the auxiliary agent in the state of stirring. Pigments can only be added when the auxiliaries are completely dispersed and uniform.
