Delivers excellent rheology control with strong sag resistance and leveling balance in waterborne systems.
Provides outstanding compatibility with a broad range of latex polymers, surfactants, and co-thickeners.
Offers high shear viscosity recovery and low spatter during application, enhancing brush/roller performance.
Ensures long-term storage stability without viscosity drift or phase separation under ambient conditions.
Non-ionic structure minimizes sensitivity to electrolytes and pH fluctuations typical in architectural coatings.
Interior and exterior architectural waterborne paints (flat to semi-gloss).
Water-based primers and undercoats for wood and drywall substrates.
Textured decorative coatings and texture plasters.
Waterborne industrial maintenance coatings for metal and concrete.
Low-VOC and zero-VOC compliant coating formulations.

Q1: What types of water-based systems is HY-304D most commonly used in?
A: HY-304D is widely employed in architectural coatings such as interior and exterior latex paints, as well as in industrial waterborne coatings including primers, topcoats, and maintenance coatings—where balanced rheology, good sag resistance, and sprayability are required.
Q2: How does HY-304D differ from cellulosic or acrylic thickeners in performance?
A: As a non-ionic polyurethane associative thickener, HY-304D provides superior shear-thinning behavior and improved flow/leveling compared to cellulosics, while offering better water sensitivity resistance and less impact on gloss than many acrylic thickeners—making it especially suitable for mid-to-high PVC formulations.
Q3: What is the recommended addition method for HY-304D in paint manufacturing?
A: HY-304D is typically added during the let-down stage, after pigment grinding and under moderate agitation. It should be diluted with water or compatible co-solvent prior to incorporation to ensure uniform dispersion and avoid localized over-thickening.
Q4: Is HY-304D compatible with common biocides and surfactants used in waterborne coatings?
A: Yes—HY-304D demonstrates broad compatibility with standard isothiazolinone and benzisothiazolinone biocides, as well as with anionic, non-ionic, and amphoteric surfactants commonly found in modern emulsion paint formulations.
