Waterbased dispersing agent

Dispersing agent for waterbased applications

Benchmark performance for inorganic pigments

Excellent overall performance for organic pigments

Broad compatibility towards different resin systems

Designed with CFRP technology for high efficiency and excellent

stability

Suited for paints that are VOC-free1 and/or carry Ecolabels2

Designed for colorants but well suited for direct grinds into

primers, gloss and semi gloss paints and for systems where

polyacrylic acid dispersing agents are not preferred

1 VOC content < 0,1% acc. EU 2004/42 ( b.p. > 250°C) (750 ppm)2 Compliant with the requirements of the European Ecolabel for “indoor paints and varnishes” 2009/544/EC and for “outdoor

paints and varnishes” 2009/543/EC

Dispersing agents

Dispex® Ultra PX 4575 – Tailor-made with CFRP

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.

Performance tests – Types of paints

Systems used for checking performance:

Architectural and wood paints

Latex gloss paint, pure acrylic Acronal® LR 9014

Façade paint, styrene acrylic Acronal® S 790

Interior silk paint, vinyl acetate Mowilith® LDM 1852

Industrial and automotive coatings

White, high gloss, stoving coating Joncryl® 8300 / Luwipal 066

White, high gloss, self-crosslinking acrylic Joncryl® 8333

Performance tests – Test methods

Test Method

Viscosity / Stability Measurement of viscosity at various shear rates before and after

storage at 50°C.

Color strength / Rub-out /

Chroma

Addition of pigment concentrate to a white (or black) base paint.

Application on black 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.

Transparency / Opacity 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 transparent the coating. dE* scattering is a measure of

light scattered: The lower the value, the higher the transparency.

Gloss Check influence of dispersing agents on gloss of the tinted paints

using a gloss meter .

VOC content EU 2004/42: b.p. > 250°C

EPA 24: 60 min 110°C convection oven
