Q1: What is the primary application area for BASF K3693SQ/ AK-7 Pigment?
A: BASF K3693SQ/ AK-7 is a high-performance organic pigment dispersion specifically developed for use in water-based industrial coatings, including coil coatings, automotive refinishes, and general metal finishing systems where excellent color strength, gloss retention, and weathering resistance are required.
Q2: Is this pigment suitable for food-contact or pharmaceutical applications?
A: No — BASF K3693SQ/ AK-7 is not certified for direct food contact or pharmaceutical use. It is formulated for industrial coating applications and does not meet regulatory requirements for such sensitive end-uses.
Q3: How should this pigment be incorporated into a water-based coating formulation?
A: The product is supplied as a ready-to-use aqueous dispersion and can be added directly during the let-down stage. It exhibits good compatibility with common acrylic, polyester, and polyurethane dispersions, and typically requires only low-shear mixing to ensure uniform distribution without destabilizing the system.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from freezing and prolonged exposure to direct sunlight. Avoid contamination with incompatible materials, and always stir gently before use to rehomogenize settled pigment particles.
