Carbon Black Resin-Free Dispersions Utilizing Orion Engineered Carbons COLOUR BLACK FW 200

This detailed document describes pigment concentrates designed for universal applications, specifically based on COLOUR BLACK FW 200. Here's a breakdown of its contents:

Formulation Components:

• Pigment Paste: COLOUR BLACK FW 200 is combined with Borchi® Gen 0451 and methoxy propyl acetate to form the pigment paste.

Dispersion Process:

• The dispersion process involves mixing the components for 60 minutes on a Skandex BAS-20 equipment, likely with 150 g Zr-silicate grinding beads (2mm) to achieve the desired particle size distribution.

Remarks:

• The document suggests that for aqueous systems applications, butyl glycol can be additionally added.

Data:

• Testing of Pigment Paste in Binder Formulations: The document provides information on the performance of the pigment paste when incorporated into specific binder formulations, such as Borchers' formulations based on Bayhydrol A 145 and Desmophen 2350.
• Haze and Gloss Data: Measurements of haze and gloss are provided for the tested formulations, offering insights into the optical properties of the final coatings.
• Particle Size: The document mentions an approximate particle size achieved during dispersion, indicating the level of dispersion achieved.
• Consistency: Described as free-flowing, indicating the ease of handling and application.
• Viscosity: Viscosity measurements are provided at defined shear rates and temperatures, indicating the flow behavior and handling characteristics of the dispersion.
• Storage Stability: Stability testing under elevated temperature conditions suggests that there is no significant alteration in viscosity and particle size over time.

Supplier Information:

• Details about the suppliers of the raw materials used in the formulation, such as Milliken and Orion Engineered Carbons, are provided.
