Carbon Black Resin-Free Dispersions Utilizing Orion Engineered Carbons Special Black 4, Special Black 101, and COLOUR BLACK FW 200

This document presents the formulation and properties of resin-free carbon black dispersions using Special Black 4, Special Black 101, and COLOUR BLACK FW 200 from Orion Engineered Carbons. It provides a breakdown of the components used in the formulation without specifying their exact percentage by weight. Here's a detailed description:

Formulation Components:

• Pigment Paste: A mixture of Special Black 4, Special Black 101, and COLOUR BLACK FW 200.
• Borchi® Gen 0851: An additive likely used for dispersion improvement or stabilization.
• Water: The solvent used for dispersing the carbon black pigments.
• Borchers® AF T: An additive that may contribute to the stability or performance of the dispersion.

Dispersion Process:

• The dispersion process involves mixing the pigment paste, Borchi® Gen 0851, water, and Borchers® AF T using appropriate equipment for a specified duration.
• Dispersion is typically performed using equipment like Skandex BAS-20, with Zr-Silicate grinding beads.

Properties:

• Particle Size: The document provides information on the particle size distribution achieved during the dispersion process, typically measured using a Grindometer.
• Viscosity: Viscosity measurements at a defined shear rate and temperature offer insights into the flow behavior and handling characteristics of the dispersion.
• Storage Stability: The stability of the dispersion over time, even under elevated temperature conditions, is crucial for its shelf life and usability.

Supplier Information:

• The document includes details about the suppliers of the raw materials used in the formulation, such as Orion Engineered Carbons and Milliken.
