QM-2041A Dispersant

Product Overview:

This polymeric polyurethane-type superdispersant, containing multiple polycaprolactone-based pigment-affinic groups, exhibits excellent wetting properties for both organic and inorganic pigments. It is particularly suitable for grinding inorganic pigments and fillers, or for systems involving the co-grinding of organic and inorganic pigments. It also possesses excellent anti-flocculation and anti-floating/streaking capabilities, making it especially suitable for the dispersion and anti-settling of matting agents in wood coatings and for coil coating systems.

Physicochemical Parameters:

Ingredients: Polycaprolactone polyurethane block copolymer

Appearance: Yellow transparent liquid

Active content: 50%

Specific gravity: XYL/PMAVBAC

Product Characteristics:

It possesses broad applicability, suitable for various coating systems, and exhibits excellent dispersion capabilities for both inorganic and organic pigments. It is ideal for systems where organic and inorganic pigments are co-milled;

As a polymeric super-dispersant, it offers excellent dispersion stability and, compared to small-molecule wetting and dispersing agents, demonstrates superior resistance to flocculation and sedimentation;

When used in coatings, it can reduce grinding time, improve film gloss, and enhance tinting strength.

Application Systems:

Suitable for various systems, used for dispersing various pigment systems, and highly versatile.
