Abstract:
Effective defoamer compositions contain two different aryl-substituted organopolysiloxanes and filler particles, and show high defoaming capability.

Claim (Index 15):
A defoamer composition, comprising\n (A1) at least one organosilicon compound comprising units of the formula\n R a (R 1 O) b R 2 c SiO (4-a-b-c)/2 \u2003\u2003(I), \n in which R are identical or different and are a hydrogen atom or a monovalent, SiC-bonded, optionally substituted hydrocarbyl radical which is aliphatic or which is aromatic and is bonded via an aliphatic carbon atom to silicon, R 1  are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbyl radical, R 2  are identical or different and are monovalent, optionally substituted, aromatic hydrocarbyl radicals bonded via a ring carbon atom to silicon, a is 0, 1, 2 or 3, b is 0, 1, 2 or 3, and c is 0 or 1, with the proviso that the sum a+b+c is less than or equal to 3, in at most 80% of all units of the formula (I), the sum a+c is 2, in at least 20% of all units of the formula (I), the sum a+c is 1, and in more than 10% of all units, c is 1,\n (A2) organosilicon compounds comprising units of the formula\n R a\u2032 (R 1 O) b\u2032 R 2 c\u2032 SiO (4-a\u2032-b\u2032-c\u2032)/2 \u2003\u2003(II), \n \n in which \n R, R 1  and R 2  have the definition stated for them above, \n a\u2032 is 0, 1, 2 or 3, \n b\u2032 is 0, 1, 2 or 3, and \n c\u2032 is 0, 1, 2 or 3, \n with the proviso that \n the sum a\u2032+b\u2032+c\u2032 is less than or equal to 3, in more than 80% of all units of the formula (II) the sum a\u2032+c\u2032 is 2, in at most 10% of all units of the formula (II) the sum a\u2032+c\u2032 is 1, and in 1-100% of all units of the formula (II) c\u2032 is other than 0,\n (B1) filler particles and/or \n (B2) organopolysiloxane resins containing units of the formula\n R 3 d (R 4 O) e SiO (4-d-e)/2 \u2003\u2003(III), \n \n in which \n R 3  are identical or different and are hydrogen or a monovalent, optionally substituted, SiC-bonded hydrocarbyl radical, \n R 4  are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbyl radical, \n d is 0, 1, 2 or 3, and \n e is 0, 1, 2 or 3, \n with the proviso that the sum d+e is less than or equal to 3 and in less than 50% of all units of the formula (III) in the organopolysiloxane resin, the sum d+e is 2, \n and optionally \n (B3) organosilicon compounds which are different from (A1) and (A2) and comprise units of the formula\n R 5 g (R 6 O) n SiO (4-g-h)/2 \u2003\u2003(IV), \n \n in which \n R 5  are identical or different and have a definition stated for R, \n R 6  are identical or different and have a definition stated for R 1 , \n g is 0, 1, 2 or 3, and \n h is 0, 1, 2 or 3, \n with the proviso that the sum g+h is less than or equal to 3 and in at least 50% of all units of the formula (IV) in the organosilicon compound, the sum g+h is 2, \n (C) optionally, polyether-modified siloxanes, \n (D) optionally, organic compounds, \n (E) optionally, water, and \n (F) optionally, further additives.
