Dispersant PX 4780 is a high-performance additive in the field of coatings and pigments. Here is an introduction to it:

Product Basics:

Chemical Type: It is a high-molecular-weight dispersant. This means it has a relatively large molecular structure, which gives it unique properties for dispersing pigments.

Solid Content: It has a solid content of 100%, ensuring a high concentration of the active ingredient for effective performance.

Amine Value: With an amine value of 20 mgKOH/g, this property is related to its reactivity and interaction with other components in the formulation.

VOC Content: The VOC content is less than 2.5%, which is beneficial for meeting environmental regulations and reducing the impact on the environment.

Performance Features:

High Efficiency in Dispersing: It is an efficient dispersant for organic pigments and carbon black. It can evenly disperse these pigments in the system, improving the color uniformity and stability of the coating or ink.

Viscosity Reduction: Even at a low addition amount, it can significantly reduce the viscosity of the pigment grinding slurry. This helps in the processing and application of the coating or ink, making it easier to achieve the desired coating effect.

Compatibility: Suitable for solvent-based and solvent-free systems, showing good compatibility with various resins and solvents commonly used in these systems.

Application Areas: It is widely used in industrial and automotive coatings, especially when a dispersant that can react with the resin is required. It can help to improve the quality and performance of the coating, such as enhancing the gloss, color saturation, and hiding power of the coating.
