  • Hydrophobic precipitated silica for defoamer formulations
    Patent number: 8614256
    Abstract: A hydrophobic precipitated silica having a BET of less than 110 m2/g, a CTAB of less than 150 m2/g, a BET/CTAB ratio of less than 3, a carbon content of greater than 3.1%, a pH of 9.7 to 10.5, a DBP of less than 230 g/(100 g), and a methanol wettability of more than 50%. The hydrophobic precipitated silica is used in compositions including defoamers, silicone rubber and HTV crosslinkable silicone rubber compositions. The hydrophobic precipitated silica is also useful as a flow assistant and carrier or anti-blocking agent.

  • Dispersing and emulsifying resins comprising polyether
    Patent number: 8420731
    Abstract: The invention relates to dispersing resins for solids which are obtainable through the partial or complete reaction of the hydroxyl groups of carbonyl-hydrogenated ketone-aldehyde resins with one or more oxiranes and, if desired, subsequent complete or partial esterification with organic and/or inorganic acids.

  • DISPERSING AGENT AND ITS USE
    Publication number: 20110144269
    Abstract: The invention relates to block copolymers of the formula E-[AB]-T, where E is an initiator fragment of a polymerization initiator capable of initiating a free-radical atom-transfer polymerization reaction, A and B are differently structured polymer blocks, and T is a chain-polymer-termination group, and also to production of these and use as dispersing agent.
