Q1: What is the primary pigment composition of Meichen Iron Oxide Yellow YX2 Color Paste?
A: The paste is based on synthetic hydrated iron(III) oxide (α-FeOOH), formulated with proprietary dispersants and rheology modifiers to ensure stable dispersion in water-based and polar solvent systems.
Q2: Is this color paste suitable for use in architectural coatings and industrial finishes?
A: Yes — YX2 is specifically engineered for high-performance aqueous architectural paints, primers, and industrial maintenance coatings, offering excellent lightfastness, alkali resistance, and minimal flocculation under shear.
Q3: How should the paste be incorporated into a formulation to ensure optimal dispersion and color development?
A: Add during the let-down or grind stage using low-to-medium shear mixing; pre-dilution with a portion of the vehicle phase is recommended. Avoid high-shear conditions after full dispersion to prevent pigment deagglomeration reversal.
Q4: Can YX2 be used in combination with other iron oxide or organic pigments?
A: Yes — it demonstrates good compatibility with common iron oxide reds and blacks, as well as selected high-stability organic yellow and orange pigments, provided pH and ionic strength are controlled within typical waterborne coating ranges.
Q5: What storage conditions are recommended to maintain long-term stability?
A: Store in sealed containers at temperatures between 5 °C and 35 °C, away from direct sunlight and freezing conditions. Avoid prolonged exposure to high humidity environments during handling.
