Resin containing carbon black pigment dispersion, based on Special Black 100 and COLOUR BLACK FW 200 using Laropal A 81

This formulation details a resin-containing carbon black pigment dispersion, primarily based on Special Black 100 and COLOUR BLACK FW 200, utilizing Laropal A 81 as the resin. Here's a breakdown of the formulation:

Formulation Components:

• Pigment Paste: The pigment paste consists of Special Black 100 and COLOUR BLACK FW 200.
• Resin: Laropal A 81, which is 60% in methoxy propyl acetate (MPA), is used as the resin.
• Additive: Borchi® Gen 0755 is added as an additive.

Dispersion Process:

• The dispersion process involves mixing the components for 60 minutes on a Skandex Shaker, likely with 1.5 times Zr-silicate grinding beads (2mm) to achieve the desired particle size distribution.

Data:

• Particle Size: The particle size achieved during dispersion is reported to be less than 10 µm.
• 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 particle size and color strength over time.

Supplier Information:

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