Chuiko Institute of Surface Chemistry of NAS of Ukraine in cooperation with Kalush Experimental Plant developed the technology for production of modified dispersed silicas with high carbon content in the chemisorbed layer.
Product can be used for gelation, stabilization of suspensions and emulsions, capsulation of biologically active objects or substances: as filler for polymers, oils, and other organic or organosilicon media: as anti-caking agent for dry mixtures, corn, seeds.
Hydrophobic silicas with high carbon content "КМ-412" // Ukrainian specifications ТU U 20.1-03291669-023:2014 / V.A. Tertykh, Iu.M. Bolbukh, R.B. Kozakevych, I.S. Protsak.
Under competition conditions an economic growth provides the use of cheap, environmentally friendly technologies. The leading global manufacturers of hydrophobic nanodispersed silicas, such as TORKEN Materials, CABOT, EVONIK Industries, use of polyorganosiloxanes as modifying agent, which provides the chemical homogeneity of surface layer and high content of grafted organic groups.
The product we developed is competitive not only by the basic physicochemical parameters (specific surface, particle size, carbon content), it is distinguished from a number of existing trade marks by the grafted layer structure which could be changed according to the demands upon the material application.
The technology based on a chemical assembling of polysiloxane layer on the surface of nanoparticles under solvent-free conditions.
