  • Process For The Continuous Preparation Of Silicone Emulsions
    Publication number: 20070203263
    Abstract: 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.
