Abstract

PURPOSE: To provide titled compsn. having excellent anti-foaming durability and foam-breaking properties and useful as an anti-foaming agent, by a method wherein a diorganopolysiloxane and a siloxane-hydroxyalkylene copolymer having a specified HLB value are blended with a silica filler.
CONSTITUTION: 100pts.wt. of a compsn. consisting of (i) 4W98wt% of diorganopolysiloxane and (ii) 96W2wt% of a siloxane-hydroxyalkylene copolymer of formula I [wherein G is gp. of formula II (wherein A is end gp.; R1 is 3W10C bivalent hydrocarbon gp.; R2 is 1W10C alkylene gp.; k, l are an integer of not less than 1; m, n are 0, 1); R is monovalent hydrocarbon gp.; a, b are a positive number determined by formula 1.9≤a+b≤2.2] having an HLB value of not less than 8.3 and a ratio of M2/M1 0.3W0.8 (wherein M1 is a MW of copolymer; M2 is a MW of oxyalkylene gp. of G), are uniformly mixed with (iii) 1W20pts.wt. of a silica filler to obtain the desired compsn.
EFFECT: The compsn. exhibits excellent anti-foaming durability and foam-breaking properties in the low-temperature region and also in the high-temperature region.
