Q1: What is the primary application advantage of Nubiperf FG-75 compared to standard ultramarine pigments?
A: Nubiperf FG-75 is specially engineered for enhanced dispersion stability and color consistency in demanding liquid systems, including water-based inks, coatings, and architectural paints—where fine particle distribution and low sedimentation are critical.
Q2: Is Nubiperf FG-75 suitable for use in food-contact coatings or plastics?
A: Nubiperf FG-75 is not certified for direct food contact applications. It complies with general industrial pigment safety requirements but is intended for non-food-contact decorative and functional coatings, inks, and plastics where regulatory approval for food contact is not required.
Q3: How does this pigment perform under alkaline conditions?
A: As an ultramarine-based pigment, Nubiperf FG-75 exhibits good stability in mildly to moderately alkaline environments typical of cementitious coatings and lime washes—but prolonged exposure to strong alkalis or acidic media may lead to color degradation and should be avoided.
Q4: What dispersion methods are recommended for optimal performance in water-based systems?
A: For best results, pre-disperse Nubiperf FG-75 using high-shear mixing or bead milling with compatible surfactants or dispersing agents. Avoid excessive heat or mechanical stress during dispersion, as it may affect particle integrity and color development.
Q5: Can Nubiperf FG-75 be used alongside titanium dioxide in white-tinted formulations?
A: Yes—Nubiperf FG-75 is commonly used in combination with TiO₂ to neutralize yellowish undertones and enhance whiteness in premium architectural paints and coatings, provided proper compatibility testing confirms no adverse interaction in the specific binder system.
