Dispersant HIDIS

Introduction HIDIS 40 is sodium salt of poly (acrylic acid) and HIDIS 45 is ammonium salt of poly (acrylic acid) type highmolecular dispersant designed for use as a pigment dispersing agent. Both give high efficiency in dispersing of titanium dioxide, calcium carbonate and other extenders into water and also in lowering the viscosity. Advantages. HIDIS 40 and HIDIS 45 are versatile dispersants which provide easy dispersion, and water resistance of emulsion paints. . HIDIS 40 and HIDIS 45 markedly lower the viscosity of mill base when pigment grinding. . HIDIS 40 and HIDIS 45 are recommended as dispersants of semi-gloss paints, sheen paints and flat paints, providing good stability of viscosity. . HIDIS 40 and HIDIS 45 provide anti-setting of pigments and no flocculation of pigments in emulsion paints for long term storage. . HIDIS 40 and HIDIS 45 provide good efficiency of grinding using small dispersant amounts. Dosages. It is recommended to use about 0.4-0.6% wt. of HIDIS 40 based on dry pigments. . HIDIS 45 is more effective than HIDIS 40. . 0.3-0.5% wt. of HIDIS 45 based on dry pigments is recommended. Safety and Handling . HIDIS 40 and HIDIS 45 are slightly irritating to the skin and eyes, and contact with these areas should be avoided. When handling wear impervious rubber gloves and goggles/facemask. . For handling/operation where possible contact may occur, a safety shower and eyewash station should be available. . Further detailed information can be found in the MSDS documentation.
