摘要: Provided is a silicone based anti-foaming agent oil compound that has not only superior anti-foaming speed but also anti-foaming performance that does not degrade with repeated use or use over a long period. The silicone based anti-foaming agent oil compound comprises: (A) an essentially hydrophobic organopolysiloxane with a viscosity at 25° C. of 2,500 to 50,000 mPa·s: 20 to 80 parts by mass; (B) a hydrophobic organopolysiloxane or cyclic organopolysiloxane having silanol groups at least at both terminals: 20 to 80 parts by mass; (C) a silane or silane condensation product: 1 to 10 parts by mass; and (D) a fine powder silica with a specific surface area of 50 m2/g or more: 2 to 10 parts by mass; where the total amount of (A) and (B) combined is 100 parts by mass. Also provided is a method for manufacturing the silicone based anti-foaming agent oil compound.

摘要: Provided is a silicone anti-foaming agent composition that not only has superior anti-foaming speed but also in which anti-foaming performance is not reduced even when used repeatedly or over a long period. The composition comprises: a polyorganosiloxane polymer crosslinked product having a polyoxyalkylene group, which includes: moiety structure (I): -R1-(R22SiO)d-R1(where R1 represents an alkylene group bonded to a silicon atom on the polysiloxane chain, R2 represents a monovalent hydrocarbon group, and d is 200 to 1000); and moiety structure (II): —(CeH2e)—O—(EO)x-(PO)y-(BO)z-R3 (where a single bond on the left end is bonded to a silicon atom on the polysiloxane chain, R3 represents a hydrogen atom, an alkyl group, an aryl group or an acyl group, e is 2 to 10, (x+y+z) is 40 to 100, x is 15 to 50, y is 15 to 50, and z is 0 to 50).

摘要: Provided is a polyether-modified silicone composition. The composition comprises (A) a polyether-modified silicone, and (B) a monool organic compound. The monool organic compound (B) is selected from (B1) a glycol ether compound having a hydrogen atom substituted by an alkyl group having from 2 to 8 carbon atoms at one end, a secondary alcoholic hydroxy group at the other end, from 2 to 3 repeating oxyalkylene units having from 2 to 4 carbon atoms, and (B2) a tripropylene glycol monomethyl ether. Isopropyl alcohol does not exceed 1 mass % of the entire composition. Applications and manufacturing methods for the composition are also provided.
