Dispex G40 Sodium salt of an acrylic copolymer Ciba Colloidal stabilizers / Dispersing agents >> Sodium Polyacrylate Polyolefins (PE, PP…) ADHESIVE >> Water-based DISPEX G40 is derivative of a family of highly effective, low viscosity dispersing agents for water-borne coating systems. The products are especially suited for the dispersion of inorganic pigments. Compared with other dispersing agents DISPEX G40 allows formulation of high-gloss / low pigment volume concentration coatings in addition to standard matt formulations. DISPEX G40 is solution of a sodium salt of an acrylic copolymer in water. It belongs to a family of products which are based on an acrylic copolymer. The copolymer is manufactured to a relatively narrow molecular weight distribution thus resulting in a consistent product quality with maximum effectiveness. DISPEX G40 is ideal dispersing agents for a wide range of water-borne coatings. The special copolymer backbone is designed for complete compatibility with polypropylene and hexylene glycols used in high proportions in water-borne high gloss coatings to promote wet edge time. Use of DISPEX G40 is especially recommended when high-gloss / low pigment volume concentration coatings are formulated. The neutralising alkali used in conjunction with the acrylic polymer can significantly impact the properties of the final coating. The sodium-based DISPEX G40 often contributes slightly negatively to the coating properties. DISPEX G40 is effective over a pH range 5-12 and up to temperatures in excess of 100°C. Compared with inorganic dispersing agents, e.g. polyphosphate products, the organic polymer based DISPEX G40 provides improved storage stability of both, the pigment dispersion and the formulated paint. There is little or no adverse reaction to high temperatures or pH changes as indicated in the graphs below, which are examples showing the accelerated effects in laboratory formulations. Solution of a sodium salt of an acrylic copolymer in water. Used as a highly effective, low viscosity dispersing agent for water-borne systems. Possesses complete compatibility with polypropylene and hexylene glycols. Contributes slightly negatively to the adhesive properties. Provides improved storage stability of both, the pigment dispersion and the formulated adhesive, and little or no adverse reaction to high temperatures or pH.
