Multi-Purpose Charcoal Black 99R - High Dispersion and Brightness for Coating
Multi-Purpose Charcoal Black 99R redefines carbon black technology with its engineered surface modification and optimized particle distribution, delivering unmatched jetness and dispersion efficiency across diverse coating applications. This next-generation pigment combines deep black intensity (CIE Lab*: L* 12±1, a* 0.5±0.2, b* 0.3±0.1) with minimal agglomeration tendencies, making it ideal for systems requiring both aesthetic excellence and functional performance.
