Laponite JS is a synthetic layered fluorosilicate modified with an inorganic polyphosphate dispersing agent. It hydrates and disperses in water to give virtually clear and colourless colloidal sols of low viscosity. At 18% concentration in water these sols will remain free flowing for at least 1 month. Application: Laponite JS may be used in coating mixes to produce smooth, coherent, electrically conductive and anti-static films on paper, film and other surfaces. It may also be used in formulations to produce inkjet receiving coatings suitable for full colour printing. Films of Laponite JS demonstrate effective barrier properties by reducing migration of macromolecules and colloidal particles. Examples of binders suitable for use with Laponite JS include polyurethane, acrylic, vinyl acetate, SBR and polyvinyl alcohol. Information provided by Southern Clay Products |
