Only the colorant fine particles is relatively easy to state uniformly dispersed in the polymer, in order to obtain a good coloring effect. Since the pigment contains many aggregated particles pesticide colorant Which is good reputation, it must be approved by high shear dispersion to break up large aggregates to form small particles of polymer to achieve the required fineness in order to obtain the desired optical effect. Use of paint and surface treatment methods can be processed into some practical form of pigment colorants pesticide manufacturers, such as pesticide colorant masterbatches, can effectively improve pigment dispersion. Some additives may be further added to improve the dispersibility of the colorant. Light and weather resistance. Kind of difficulty with the polymer and other additives, organic pigments migration (especially plasticizers and softeners) have a great relationship. Experiments show that large-scale pesticide colorant companies, in general, organic acid salts mobility is relatively small; the higher molecular weight less than the lower of migration. Heat resistance. Excellent heat stability is an important indicator of plastic colorants, most inorganic pigments are better heat resistance, and can basically meet the requirements of plastics processing, and the organic colorant heat resistance is poor.
