In the realm of coatings, achieving a stable, uniform dispersion of pigments and fillers is paramount to the final product’s quality, appearance, and performance. NINGBO INNO PHARMCHEM CO.,LTD. offers advanced acrylic acid homopolymers, like TH-445, that serve as highly effective dispersants, providing significant benefits to coating manufacturers.

Coatings, whether for decorative or protective purposes, rely on finely dispersed solid particles (pigments and fillers) within a liquid medium. Ineffective dispersion can lead to several issues: increased viscosity, poor color development, sedimentation, poor film formation, and reduced gloss. Acrylic acid homopolymers, with their unique molecular structures, are adept at overcoming these challenges. TH-445, specifically, demonstrates excellent performance as a pigment dispersant for coatings, contributing to lower application viscosity and improved rheological properties.

The primary function of an acrylic acid homopolymer in a coating formulation is to prevent the agglomeration of pigment and filler particles. The polymer chains adsorb onto the surface of these particles, creating steric or electrostatic repulsion that keeps them separated. This leads to a more stable dispersion, ensuring that the coating remains homogeneous during storage and application. For instance, when used as a calcium carbonate grinding dispersant, it facilitates finer grinding and maintains the stability of the resulting slurry.

Moreover, the use of acrylic acid homopolymers can significantly reduce the amount of dispersant required, leading to cost efficiencies without compromising performance. Their effectiveness at low dosages means less additive is incorporated into the formulation, which can be beneficial for maintaining other properties of the coating, such as film hardness or water resistance. This makes them an attractive option for formulators looking to optimize their recipes.

TH-445’s specific characteristics, such as its excellent calcium chelation, are also beneficial in water-based coating systems where water hardness can otherwise lead to issues with pigment dispersion and film formation. By mitigating these effects, our acrylic acid homopolymer ensures that water-based coatings can achieve the high performance often associated with solvent-based systems.

For manufacturers in the paint and coatings industry, sourcing reliable and high-performing dispersing agents is critical.
