Sodium Salt Dispersant HQ-5042

Sodium Salt Dispersant HQ-5042

Product Introduction:

HQ-5042 is a sodium polycarboxylate dispersant that achieves an excellent balance among cost, production process and end-product performance. It features low foaming and improves coating flowability, with outstanding color acceptance, initial viscosity reduction during dispersion and storage stability. Stable low-viscosity slurries can be prepared, and it also delivers good freeze-thaw stability.

Application Fields:

Water-based systems including architectural coatings, industrial coatings, pigment & filler slurries, coated paper coatings, water-based adhesives, water-based inks, etc.

Usage & Dosage:

Recommended dosage: 0.1–1.0% based on the mass of pigments and fillers (solid-to-solid). Add the dispersant into water and mix thoroughly, then feed pigments under stirring before dispersion and grinding.

Details

Physical & Chemical Indexes:

Performance Features:

Free of hazardous substances such as APEO and formaldehyde, compliant with environmental regulations including REACH and GB/T 18582.

High dispersion efficiency and excellent loading capacity for pigments and fillers.

Excellent freeze-thaw stability to resist phase separation during low-temperature storage.

Improves coating flow and leveling to facilitate construction operation.

Low foaming characteristic with minimal foam generation during dispersion, reducing supplementary defoamer dosage and preventing crater defects on paint films.

Cost-effective with low required dosage; its optimal usage level is 5%–10% lower than conventional dispersants, cutting overall formulation cost.
