Dispersant PU 4063 is a remarkable additive with several notable features and applications:

Chemical Composition and Physical Properties:

It is a modified polyurethane-based product. This chemical composition gives it unique properties that set it apart from other types of dispersants.

Physically, it is a liquid with a yellowish appearance. It has a solid content of approximately 45% and a density of around 0.99 g/cm³ at 20°C.

Functions and Performance:

Excellent Dispersing Ability: This dispersant is highly effective in dispersing both inorganic and organic pigments. It helps to evenly distribute the pigment particles in the solvent, resulting in a more homogeneous and stable pigment dispersion. This not only improves the color uniformity of the final product but also enhances its overall quality.

Reduction of Dispersing Time and Viscosity: It significantly reduces the time required for pigment dispersion, improving the efficiency of the production process. Additionally, it lowers the mill base viscosity, making it easier to handle and process the pigment dispersion.

Prevention of Pigment Flooding and Floating: Dispersant PU 4063 prevents the undesirable phenomena of pigment flooding (excessive spreading) and floating, ensuring that the pigments remain well-dispersed and evenly distributed throughout the coating or paint system. This leads to better coating performance and appearance.

Enhancement of Color Intensity and Gloss: By improving the dispersion of pigments, it promotes high color intensity and good gloss in the final product, giving it a more attractive and professional finish.
 

Compatibility and Application Areas:

Wide Compatibility with Binders: It is easily compatible with a broad range of binders, which makes it suitable for use in various coating and paint formulations. This flexibility allows formulators to incorporate it into different systems without significant compatibility issues.

Application in Different Coatings and Paints: It is widely used in 2-component polyurethane paints, 2-component epoxy paints, unsaturated polyester, stoving paints, and air-drying paints. Its performance characteristics make it an ideal choice for these applications, where high-quality pigment dispersion and good coating properties are required.

In general, Dispersant PU 4063 is a valuable additive for the coatings and paint industry, offering excellent dispersing performance, improved processing efficiency, and enhanced product quality in a variety of applications.
