Latest Patents
Freeman's latest patents include a coating composition that comprises submicron calcium carbonate-comprising particles. This innovative process allows for the preparation and use of these particles in various coating compositions. The composition features an aqueous dispersion of submicron natural ground calcium carbonate particles contained in a liquid binder. Depending on the presence of certain additives, the resultant coating can serve as either a clear coat or a glossing and opacifying coating. The clear coating contains at least one ground natural calcium carbonate with a median diameter of between 0.05 and 0.15 micrometers. In contrast, the glossing and opacifying coating includes at least one ground natural calcium carbonate with a median diameter of between 0.05 and 0.3 micrometers, along with a pigment that has a refractive index of greater than or equal to 2.5. Additionally, Freeman has developed high refractive index copolymers with reduced glistenings, which are particularly suitable for use as ophthalmic device materials. These copolymers consist of a high molecular weight, reactive, linear polyethylene glycol component.
