Description

C.I. Pigment Brown 23 is a high-performance, synthetic inorganic pigment known for its excellent heat stability and chemical resistance. This pigment is valued for providing durable, opaque brown coloration in demanding industrial applications. It is primarily used by manufacturers in the coatings, plastics, and construction materials industries seeking consistent quality and reliable performance.

Application

• Industrial Coatings: Used in heat-resistant paints, coil coatings, and heavy-duty protective finishes for machinery and architectural elements.
• Plastics and Masterbatches: Imparts stable brown coloration to engineering plastics, PVC, polyolefins, and synthetic fibers during high-temperature processing.
• Construction Materials: A key colorant for concrete paving stones, roofing tiles, and other cement-based products requiring UV and weather stability.
• Printing Inks: Employed in specialty printing inks, including those for packaging and decorative laminates, where opacity and lightfastness are critical.
• Ceramic Glazes and Enamels: Provides consistent brown tones in ceramic frits and vitreous enamels applied to glass and metal substrates.
