LAPONITE-S 482

Highly shear thinning layered silicate rheological additive for water-borne systems. Used in highly filled surface coatings and general applications. Synergistic benefits when used in combinations with polymer based co-thickeners. Forms low viscosity pre-mixes in water, which thicken on addition to formulations. LAPONITE S482 is a synthetic layered silicate modified with a patented dispersing agent. It hydrates and swells in water to give translucent and colourless colloidal liquid dispersions known as sols. At 25% solids concentration in water, these will remain free flowing for up to 1 year. On addition of small quantities of electrolyte, or on addition to formulations containing eg resins, surfactants or pigments, highly thixotropic gels are formed rapidly. LAPONITE S482 must be dispersed in water before use and may be added to formulations at any point during manufacture. It is used to impart a shear sensitive structure to a wide range of waterborne formulations including DIY and industrial surface coatings, household cleaners, ceramic and agrochemical products. LAPONITE S482 dispersions may be coated onto paper or other surfaces to give smooth, coherent, and electrically conductive films.
