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. Performance in black color pastes: MONARCH 650 specialty carbon black can be dispersed in dimethyl silicone fluid easily through conventional compounding mixers, e.g., planetary mixer, 3-roller mixer, kneader, twin screw extruder etc. Figure 1 shows the Fineness (µm) measurement of a black color paste containing 27wt% carbon black in 350cst dimethyl silicone fluid. The paste containing MONARCH 650 specialty carbon black exhibited the best fineness. Information provided by Cabot Corporation |
