Q1: What is the primary chemical composition of CATHAYPURE Brown BR1115?
A: CATHAYPURE Brown BR1115 is a mixed-metal oxide pigment based on iron and manganese oxides, engineered for thermal and chemical stability in demanding industrial applications.
Q2: Is BR1115 suitable for use in food-contact plastics or coatings?
A: BR1115 is not certified for direct food-contact applications. It is intended for general-purpose industrial coatings, construction materials, and non-food-related plastic coloration where regulatory compliance with food safety standards is not required.
Q3: How does BR1115 perform under high-temperature processing conditions?
A: As an inorganic oxide pigment, BR1115 exhibits excellent thermal stability and retains its color integrity during standard polymer processing (e.g., extrusion, injection molding) and ceramic firing up to approximately 800°C.
Q4: What dispersion methods are recommended for optimal color development in liquid systems?
A: For best results in paints, inks, or slurries, BR1115 should be dispersed using high-shear mixing or bead milling. Pre-wetting with compatible solvents or surfactants may improve deagglomeration and uniform distribution.
Q5: Can BR1115 be used alongside organic pigments in hybrid color formulations?
A: Yes — BR1115 is chemically inert and generally compatible with most organic pigments, enabling stable hybrid shades. However, compatibility testing is advised in final formulations to ensure no adverse interactions affect dispersion stability or hue consistency.
