Q1: What is the primary chemical composition and crystal structure of BASF L2817?
A: BASF L2817 is a synthetic iron oxide pigment based on hematite (α-Fe₂O₃), offering high chemical stability and excellent lightfastness. Its crystalline structure contributes to consistent color performance and thermal resistance in demanding applications.
Q2: Is BASF L2817 suitable for use in water-based coatings and cementitious systems?
A: Yes — L2817 is specifically engineered for excellent dispersibility and compatibility in aqueous environments, including architectural paints, plasters, and concrete colorants. Its surface treatment ensures good wetting and reduced flocculation in both low- and high-pH matrices.
Q3: How does BASF L2817 perform under elevated temperature conditions?
A: As a thermally stable iron oxide, L2817 retains its color integrity and structural properties up to approximately 800 °C in inert or oxidizing atmospheres, making it suitable for ceramic glazes, refractory linings, and high-temperature polymer processing where organic pigments would degrade.
Q4: Can BASF L2817 be used in food-contact or pharmaceutical-grade applications?
A: BASF L2817 is not certified for direct food contact or pharmaceutical use. It is intended for industrial, construction, and general-purpose coating applications. For regulated end uses, consult BASF’s regulatory documentation and confirm suitability with your compliance team.
Q5: What is the typical dosage range when using L2817 in architectural coatings?
A: Dosage depends on desired opacity, shade intensity, and formulation requirements, but L2817 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in finished coatings — due to its high tinting strength and efficient light absorption.
