Q1: What is the primary function of Acrysol DR-72 in water-based formulations?
A: Acrysol DR-72 is a hydrophobically modified alkali-swellable emulsion (HASE) thickener designed to provide efficient rheology control—particularly high-shear viscosity and sag resistance—in aqueous systems such as architectural coatings, adhesives, and cleaners.
Q2: How does Acrysol DR-72 differ from traditional ASE or HEC thickeners?
A: Unlike conventional alkali-swellable emulsions (ASE), DR-72 incorporates hydrophobic modifications that enable stronger associative network formation, resulting in superior flow and leveling balance, enhanced spatter resistance, and improved compatibility with surfactants and co-thickeners.
Q3: Is Acrysol DR-72 compatible with common biocides and defoamers used in industrial coatings?
A: Yes, DR-72 demonstrates broad compatibility with widely used isothiazolinone and formaldehyde-releasing biocides, as well as silicone and mineral oil-based defoamers—though compatibility should always be verified in the final formulation due to system-specific interactions.
Q4: What pH range is required for optimal performance of Acrysol DR-72?
A: DR-72 requires alkaline activation and performs best in formulations with pH ≥ 8.0; typical use involves post-addition adjustment to pH 8.5–9.5 using common neutralizing agents like AMP-95 or NaOH.
Q5: Can Acrysol DR-72 be used in low-VOC or zero-VOC formulations?
A: Yes, DR-72 is inherently low in VOC and supports compliance with stringent environmental regulations—it contains no added solvents or volatile organic carriers, making it suitable for low- and zero-VOC architectural and industrial coating systems.
