Q1: What is the primary particle morphology and metallic composition of DOROLAN 17 0?
A: DOROLAN 17 0 is an aluminum-based metallic pigment with a controlled flake morphology, optimized for high brightness and uniform orientation in coating films. It features a standard aluminum core without intentional alloying elements or surface treatments beyond ECKART’s proprietary stabilization process.
Q2: Is DOROLAN 17 0 suitable for water-based systems?
A: Yes — DOROLAN 17 0 is formulated for compatibility with both solvent-borne and water-based industrial coatings, including acrylic and polyurethane dispersions. Its surface stabilization helps minimize hydrogen evolution and supports stable dispersion in neutral to mildly alkaline aqueous media.
Q3: How should DOROLAN 17 0 be incorporated into a coating formulation to ensure optimal orientation and gloss?
A: For best results, incorporate DOROLAN 17 0 during the let-down stage using low-shear mixing to preserve flake integrity. Pre-dispersing in a compatible resin solution or using recommended wetting agents improves alignment during film formation. Avoid high-shear grinding or prolonged mechanical stress that may damage the flakes.
Q4: What are typical dosage ranges for achieving strong metallic effect without compromising film integrity?
A: Dosage depends on formulation requirements and desired visual intensity, but DOROLAN 17 0 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to total formulation solids — to balance metallic appearance, transparency, and mechanical performance.
