DISPEX CX 4340 is a derivative of a family of highly effective, low viscosity dispersing agents for water-based coating systems, especially suitable for the dispersion of inorganic pigments. Compared with other dispersing agents DISPEX CX® 4340 allows formulations of high-gloss/low-pigment-volume-concentration coatings in addition to standard matt formulations. This dispersing agent is part of a family of products based on an acrylic copolymer. The copolymer is manufactured to a relatively narrow molecular weight distribution, resulting in a consistent product quality with maximum effectiveness.

DISPEX CX 4340 is an ideal dispersing agent for a wide range of water-based coatings. The special copolymer backbone is designed for complete compatibility with polypropylene and hexylene glycols used in high proportions in water-based high-gloss coatings to promote wet edge time. The use of this product is especially recommended when high gloss/low-pigment-volume-concentration coatings are formulated. The neutralizing alkali used in conjunction with the acrylic polymer can significantly impact the properties of the final coating. The sodium based DISPEX CX 4340 often contributes slightly negatively to the dry film coating properties.
