Dispersing agentsDispex® Ultra PX 4575 – Tailor-made with CFRP A-Block B-Block stabilizer block pigment affinic block Compatible with paint system, Anchoring onto pigment e.g. resins and solvents resin & solvent specific ! pigment specific ! Dispex® Ultra PX 4575 is based on CFRP technology and a new pigment stabilizing mechanism that enhances electrosteric stabilization. CFRP also enables the precise design of the structured polymer to improve compatibility and stabilizing properties especially for inorganic pigments.

  • 16. Performance tests – Test methodsTest MethodViscosity / Stability Measurement of viscosity at various shear rates before and after storage at 50°C. Addition of pigment concentrate to a white (or black) base paint. Application on blackColor strength / Rub-out / Chroma and white card and check rub-out: Measurement by colorimeter. Chroma is the saturation of a color, the higher the chroma the “cleaner” a color. Measurement of opacity by light absorption. At a value of 100 all light is absorbed and coating is completely opaque: The lower the opacity value, the more transparentTransparency / Opacity the coating. dE* scattering is a measure of light scattered: The lower the value, the higher the transparency. Check influence of dispersing agents on gloss of the tinted paints using a glossGloss meter . EU 2004/42: b.p. > 250°CVOC content EPA 24: 60 min 110°C convection oven 16
