Abstract
A method for the preparation of a powder mixture of cured silicone microparticles and inorganic microparticles is disclosed, said method comprising (I) forming a water-based suspension of (A) a plurality of cured silicone microparticles having an average diameter of 0.1 to 200 micrometers, (B) a plurality of inorganic microparticles having an average particle diameter of 0.1 to 200 micrometers and, optionally, (C) at least one surfactant; and (II) removing the water from said water-based suspension. The resultant powder mixture is relatively free from agglomeration and may be easily dispersed in organic resins to form a homogeneous mixture for such applications as paints and coatings.
