Abstract:
The present invention relates to silicone (meth)acrylate particles, to a process for preparing such silicone (meth)acrylate particles including the steps of: a) obtaining an emulsion composed of water and an organic phase comprising organopolysiloxanes modified terminally and/or laterally with acrylate groups, and b) polymerizing the inner phase to completion by means of a free-radical initiator, the free-radical initiator being added to the outer phase (aqueous phase) in a concentration of 0.1 to 40% by weight based on the inner phase, and to the use of the particles alone or in a mixture with further particles, pigments and/or further customary additives in the form of powders or dispersions in coating, adhesive or sealant materials, in polymers, in defoamers, in wetting and levelling aids, in cosmetic or pharmaceutical formulations and care products, in cleaning and detergent compositions, or in applications for modifying the interface properties of solid and liquid substrates, for example tactile properties, hydrophobization, or sliding and/or release properties.
