MONARCH 650 specialty carbon black is especially suited for black color paste preparation with dimethyl silicone fluid as a matrix. This product allows for easy dispersion by conventional compounding mixers. It also enables excellent heat stability. The color paste is suitable for room temperature vulcanized (RTV) silicone sealant formulations that require excellent jetness and gloss to provide a feeling of luxury and durability. Key applications: MONARCH 650 specialty carbon black is suitable for use in RTV silicone sealants for construction and industrial applications.
