摘要: Stable aqueous organosilicon dispersions particularly useful for the hydrophobing of construction materials are prepared by first preparing a homogenous mixture of organopolysiloxanes and hydrophobic silica filler, and dispersing this mixture together with an alkylalkoxysilane bearing at least one C4 or greater alkyl group into water.

摘要: Aqueous silicone emulsions are prepared by emulsifying silicone, emulsifier, and water in a first high shear mixer, and introducing the viscous phase thereby obtained obtained, optionally with further components, into a second high shear mixture. A set point for temperature and pressure after each mixer is established, and the measured temperatures and pressures are used in a feedback loop to adjust process parameters such that the set points are maintained.
