The cooling method with an intelligent temperature control system, whether it is circulating water cooling or air cooling, can stably cool the materials to room temperature to avoid the adverse effects of temperature changes on product performance. Finally, auxiliary ingredients such as stabilizers, surfactants, solubilizers and polymer dispersants in the formula ensure the stability, dispersibility and compatibility of the system.
