Incorporation and Processing Instructions
To achieve the best performance, the additives should be added to the grind first, followed by the pigment. Premix the resin and solvent components of the grind, then slowly add the additives while stirring. Do not add the pigment until the additives are well mixed.

Functions and uses of dispersants:
Dispersion: Dispersants can disperse solid particles or liquids into liquid media and prevent them from reaggregating. Through the action of surfactants, they encapsulate particles or droplets in micellar structures, making them dispersed evenly, thus forming stable suspensions or emulsions and preventing precipitation and sedimentation.
Preventing precipitation and aggregation: Dispersants can effectively prevent particles or powders from precipitating or aggregating in liquids by increasing their surface activity. They can improve the color development of slurries, making gloss and chromaticity greatly improved, thereby improving the appearance and reliability of applied products.
Stabilization: Dispersants can provide higher dispersion stability and prevent particles from reaggregating to form agglomerates. They reduce the interaction force between particles and hinder the aggregation of particles, thereby maintaining the uniformity and stability of the suspension.
Improving fluidity: Dispersants can improve the flow properties of fluids. When solid particles or droplets are evenly dispersed, they can reduce the viscosity and viscosity of the fluid and improve the flow properties of the fluid.
Thickening: Some dispersants have a thickening effect, forming a colloid or gel structure in the liquid, increasing the viscosity and viscosity of the liquid. This is very useful in some applications, such as seasonings, coatings and adhesives. Adjusting properties: Dispersants can adjust the properties of suspensions or emulsions, such as pH, temperature stability, conductivity, etc. They can improve product quality, process performance and use effects.
Dispersing agent
TWide range of applications: Dispersants are widely used in many fields, including inks, paints, coatings, textile printing and dyeing, inkjet inks, pulp and paper, electronic materials, pesticides, nanomaterials and other chemical fields. Dispersants have an important impact on the efficiency of the production process and product quality.
It should be noted that although dispersants have multiple functions and uses, it is still necessary to control the amount used and choose the appropriate type of dispersant when using them. Improper use may cause harm to human health and the environment. In addition, when using dispersants, relevant safety operating procedures and standards should be strictly followed to ensure the safety of production and use.
