Dispersant PX 4701 is a remarkable product with several outstanding features:

Chemical Composition and Manufacturing Process:

It is a 100% active dispersant of the acrylic block co-polymer family. It is made through controlled free radical polymerization, a technology that enables the production of polymeric dispersants with a defined polymer architecture and low polydispersity.

Physical Properties:

It is a liquid with an amber to brownish color. This physical form makes it easy to handle and incorporate into various formulations.

Performance Characteristics:

High Dispersing Efficiency: PX 4701 is a highly efficient dispersant for both organic pigments and carbon blacks. It can evenly disperse these pigments in different formulations, ensuring uniform color and excellent color strength.

Viscosity Reduction: It has the ability to significantly reduce the viscosity of the system, which is beneficial for the processing and application of the formulation. This helps to improve the flowability and sprayability of inks and coatings, for example.

Excellent Storage Stability: The dispersant provides excellent storage stability, ensuring that the dispersed pigments remain stable over an extended period. This is crucial for the long-term quality and performance of the final product.

Compatibility and Application Areas:

Broad Compatibility: It shows broad compatibility with different ink systems, including UV-curable, solvent-based, and water-based formulations. It is also compatible with a wide range of pigments, making it a versatile additive for various applications.

Recommended Applications: It is especially recommended for high-performance systems such as inkjet inks, UV-curable inks, and water-based flexographic inks. Additionally, it can be used in resin-free pigment concentrates and is suitable for industrial and automotive coatings.

Dosage and Shelf Life:

Dosage: The appropriate use levels of PX 4701 depend on factors such as the pigment selection, dispersing medium, and letdown composition. Generally, for inkjet ink formulations (UV-curable, solvent-based, and water-based), the optimum use level can be in the range of 2.5 - 10% calculated on the pigment load.

Shelf Life: When stored in its original unopened container in a cool and dry place, PX 4701 has a shelf life of up to 4 years from the date of manufacture.
