Q1: What is the primary chemical composition of BR-832M?
A: BR-832M is a mixed-metal oxide pigment based on iron and chromium oxides, engineered to deliver stable brownish-red hues with high thermal and lightfastness. Its inorganic matrix ensures low volatility and resistance to degradation under processing conditions.
Q2: Is BR-832M suitable for use in food-contact plastics?
A: Yes — BR-832M is formulated to meet global regulatory expectations for pigments in food-contact applications, including compliance with FDA 21 CFR §178.3297 and EU Framework Regulation (EC) No 1935/2004. It is non-leaching and chemically inert under typical polymer processing and end-use conditions.
Q3: How does BR-832M perform under high-temperature processing?
A: BR-832M exhibits excellent thermal stability, retaining color integrity and dispersion quality during extrusion, injection molding, and compounding up to 300°C. Its robust crystalline structure minimizes color shift or blooming in thermoplastics such as polyolefins and engineering resins.
Q4: Can BR-832M be used in water-based coatings and inks?
A: Yes — BR-832M is compatible with aqueous systems when properly surface-treated or dispersed using standard wetting agents. It delivers consistent opacity and rheological behavior in architectural paints, industrial coatings, and pigment concentrates without significant settling or flocculation.
