Description
Overview:
Water-based wetting & dispersing agent HXFS04 is a sodium polycarboxylate anionic surfactant dispersant with excellent wetting and dispersing properties. Its main component is a sodium polyacrylate polymer solution; at 25°C, this agent appears as a colorless clear liquid, with water as the solvent and an active content of 45%.
Key features of water-based wetting & dispersing agent HXFS04 include low foaming, which enhances coating fluidity and stabilizes slurry viscosity effectively. It also reduces grinding viscosity, boosts coating storage stability, improves gloss and leveling, and has higher dispersion efficiency than conventional water-resistant dispersants (allowing lower dosage). Additionally, it enables low-viscosity coatings/pastes with minimal addition, maintains stable viscosity without fluctuation, enhances film water resistance (ideal for high-gloss coatings), avoids floating/flooding, provides sufficient wetting without extra agents, and has fast-breaking foam for better application.
In applications, water-based wetting & dispersing agent HXFS04 is mainly used in coated paper coatings, water-soluble paints (for dispersing inorganic pigments/fillers like clay, calcium carbonate, titanium dioxide), and exterior/interior wall architectural coatings.
