| Product highlights: MONARCH®465 specialty carbon black is designed to be used in room temperature vulcanized (RTV) silicone sealants for marble construction. It imparts jetness, blue undertone, gloss, and heat stability. MONARCH®465 specialty carbon black is especially suited for black color paste preparation with hydroxyl terminated polydimethylsiloxane as a matrix. This product allows for easy dispersion by conventional compounding mixers. It also enables excellent heat stability. Key applications: MONARCH®465 specialty carbon black is suitable for use in RTV silicone sealants for construction and industrial applications. Performance in black color pastes: MONARCH®465 specialty carbon black can be dispersed in hydroxyl terminated polydimethylsiloxane 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, the model formulation containing 26wt% carbon black in 1500 cst hydroxyl terminated polydimethylsiloxane. The paste containing MONARCH®465 specialty carbon black exhibited good fineness. Information provided by Cabot Corporation |
