Laponite® RD is a synthetic layered silicate. It is insoluble in water but hydrates and swells to give clear and colorless colloidal dispersions. At concentration of 2% or greater in water, highly thixotropic gels can be produced.
Used for imparting a shear sensitive structure to a wide range of water-based formulations. These include household and industrial surface coatings, cleansers, ceramic glazes, agrochemical, oilfield and horticultural products.
A useful mixture for removing hide glue when repairing violins can be made using Laponite® RD and Surfynol® 61.
Laponite® RD is hygroscopic and should be stored under dry conditions.
