Abstract
The functional role of sepiolite in organosilicate composites is investigated. It is demonstrated that the addition of the organomodified sepiolite to organosilicate composites during their fabrication in amounts of 1 wt % increases the thixotropy and pseudoplasticity of “polydimethylphenylsiloxane-silicate-inorganic pigment” suspensions and prevents sedimentation of pigments and fillers, as well as the formation of dense sediments in the course of storage. Upon introduction of this stabilizing additive, the physicomechanical and protective properties of organosilicate coatings remain good.
