Dispex CX 4325 is a highly effective, low-viscosity dispersing agent for water-based coating systems, especially suitable for the dispersion of inorganic pigments.

Dispex® CX 4325 was developed to allow the formulation of coating systems containing partly soluble, reactive pigments such as oxides, dioxides, carbonates, and phosphates.

Applications for DISPEX CX 4325

Dispex CX 4325 is an ideal dispersing agent for a wide range of water-based coatings. The very special polymer backbone provides an extraordinary combination of properties, the hydrophobic character of the resin together with high efficiency as a dispersing agent which makes Dispex CX 4325 especially suitable for high-performance water-based coatings where resistance to humidity is of prime importance. It also tolerates the presence of partly soluble pigments such as those commonly used in anticorrosion coatings which would normally lead to the instability of the liquid paint system.

Typical areas of use for Dispex CX 4325 are exterior wood coatings and coatings on metal surfaces.

Dispex CX 4325 is effective over a pH range of 5 – 11 and at temperatures exceeding 100 °C (212 °F).
