Q1: What types of pigments is NUOSPERSE FA 620 especially effective for?
A: NUOSPERSE FA 620 is particularly effective for dispersing high-surface-area inorganic pigments (e.g., titanium dioxide, iron oxides) and many organic pigments commonly used in architectural, industrial, and protective coatings. Its molecular design supports strong anchoring and steric stabilization in aqueous systems.
Q2: Can NUOSPERSE FA 620 be used in both acrylic and styrene-acrylic latex systems?
A: Yes — NUOSPERSE FA 620 is compatible with a broad range of waterborne polymer systems, including pure acrylic, styrene-acrylic, vinyl acetate copolymers, and hybrid dispersions. It maintains performance across varying pH and ionic strength conditions typical in modern latex formulations.
Q3: How does NUOSPERSE FA 620 improve gloss and color development in finished coatings?
A: By promoting rapid wetting and uniform deagglomeration of pigment particles, NUOSPERSE FA 620 helps achieve narrow particle size distribution and reduced flocculation. This leads to improved light scattering efficiency, higher color strength, better transparency where needed, and enhanced film clarity and gloss retention.
Q4: Is NUOSPERSE FA 620 suitable for low-VOC or zero-VOC formulations?
A: Yes — NUOSPERSE FA 620 is a non-ionic, low-foaming dispersant with negligible VOC contribution. It supports formulators in meeting stringent environmental regulations without compromising dispersion stability or application performance.
