Q1: What is the primary application field for Graphtol F3RK70?
A: Graphtol F3RK70 is a high-performance black pigment dispersion specifically developed for demanding industrial coating and ink applications, including gravure and flexographic inks, as well as solvent- and water-based industrial coatings where excellent jetness, gloss, and dispersibility are required.
Q2: Is Graphtol F3RK70 suitable for water-based systems?
A: Yes — Graphtol F3RK70 is formulated as a stable aqueous dispersion and is compatible with many water-based polymer systems, including acrylics, styrene-acrylics, and polyvinyl acetate emulsions. Performance may vary depending on pH, ionic strength, and binder architecture, so compatibility testing is recommended.
Q3: How should Graphtol F3RK70 be incorporated into formulations?
A: It is typically added during the let-down or post-addition stage under low-shear conditions to preserve dispersion integrity. Pre-dilution with compatible solvents or water may aid uniform incorporation. Avoid high-shear mixing that could destabilize the pigment particles or induce flocculation.
Q4: What is the typical dosage range for optimal performance?
A: Dosage depends on the specific formulation requirements and desired color strength, but Graphtol F3RK70 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the total formulation — to achieve deep black shades with good transparency or opacity as needed.
