Solvent borne pigment concentrates based on iron oxides pigments, containing Laropal A 81

This formulation describes solvent-borne pigment concentrates based on iron oxide pigments, incorporating Laropal A 81 as part of the formulation. Here's a breakdown:

Formulation Components:

• Pigment Paste: The formulation includes Bayferrox Yellow 3920 and Bayferrox Red 130M as iron oxide pigments.
• Resin: Laropal A 81, which is 60% in methoxy propyl acetate (MPA), is utilized as a resin.
• Additive: Aerosil R 972 is included as an additive.
• Solvent Mixture: A mixture of methoxy propyl acetate and butyl acetate serves as the solvent.

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 15 µm.
• Viscosity: Viscosity measurements indicate the flow behavior and handling characteristics of the dispersion under defined shear rate and temperature conditions.
• 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 Lanxess, Borchers, Evonik, and BASF, are provided.
