Solvent borne Organic pigment concentrates, binder free

This formulation outlines solvent-borne pigment concentrates without binders, intended for various applications. Here's a breakdown of the components:

Formulation Components:

• Pigment Paste: The formulation consists of four pigment pastes labeled A, B, C, and D, each containing different pigment types:
  • Pigment Paste A: Hostaperm ER 02 (P.V.19)
  • Pigment Paste B: Irgazin® Red L 3660 (P.R.254)
  • Pigment Paste C: DPP (P.Y.213)
  • Pigment Paste D: Hostaperm gelb H5G (P.O.36)
• Additive: Borchi® Gen 0451 is included as an additive.
• Solvent Mixture: Methoxy propyl acetate serves as the primary solvent for the formulation.
• Aerosil 200: Included in small amounts to potentially aid in dispersion.

Dispersion Process:

• The dispersion process involves mixing the components for 60 minutes on a Skandex BAS-20, likely with 150 g 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.
• Consistency: Described as free-flowing, indicating ease of handling and application.
• Viscosity: Viscosity measurements at a shear rate of 100 s^-1 and 23 °C indicate the flow behavior of the concentrates. The viscosity is reported to be less than 350 mPa.s.
• Storage Stability: Stability testing under elevated temperature conditions suggests that there is no significant alteration in viscosity and particle size over time.
