With the improvement of people's awareness of food additive safety, to develop natural, nutritious and versatile natural colorants it has become the development direction of the colorant colorant only easier to tiny particles uniformly dispersed in the polymer state pesticide colorant Which high-volume, in order to obtain a good coloring effect. Since the pigment contains a lot of aggregated particles must therefore be dispersed by high shear force to break up large aggregates to form small particles of polymer to achieve the fineness of pesticide colorants companies require in order to obtain the desired optical effect. Use of paint and surface treatment methods can be processed into some practical form pigments, such as masterbatches, can effectively improve pigment dispersion. Some additives may be further added to improve the dispersibility of the colorant. Light and weather resistance.
