Q1: What is the primary function of ACROPOL 63-990 in coating formulations?
A: ACROPOL 63-990 is a specialty acrylic resin designed to act as a rheology modifier and film-forming aid, enhancing viscosity control, sag resistance, and substrate wetting—particularly in low-VOC, waterborne industrial and protective coatings.
Q2: Is ACROPOL 63-990 compatible with common waterborne polymer systems?
A: Yes, it demonstrates broad compatibility with acrylic, styrene-acrylic, and polyurethane dispersions, and is typically added during the let-down stage without requiring pH adjustment or high-shear dispersion.
Q3: How does ACROPOL 63-990 affect drying behavior and final film properties?
A: It supports rapid water evaporation and coalescence while contributing to improved block resistance, scrub resistance, and gloss retention in dried films—without compromising flexibility or adhesion on diverse substrates.
Q4: Can ACROPOL 63-990 be used in food-contact compliant coatings?
A: While ACROPOL 63-990 is formulated for use in coatings intended for indirect food contact applications, final regulatory compliance depends on the full formulation, processing conditions, and applicable regional requirements—formulators should conduct full regulatory validation.
