    • PURPOSE: To obtain the titled composition excellent in defoaming capacity, by mixing organopolysiloxane having an oxyalkylene group and a perfluoroalkyl group, organopolysiloxane containing a perfluoroalkyl group and a siliceous filler.
      CONSTITUTION: The titled composition consists of 100pts.wt. of organopolysiloxane (1) having an oxyalkylene group and a perfluoroalkyl group shown by formula I , 0.1W200pts.wt. of organopolysiloxane (2) having a perfluoroalkyl group and a siliceous filler (3) in an amount corresponding to 0W20pts.wt. per 100pts.wt. of the sum amount of (1) and (2). In the above formulae, R is H or an 1W6C monovalent hydrocarbon group, G is a 2W4C oxyalkylene group represented by formula III (wherein A is a terminal group, R' is 3W4C divalent hydrocarbon group, R
      2 is a 2W4C divalent hydrocarbon group, K and l are a positive integer of 1 or more and m and n are 0 or 1), Q is a monovalent org. group having an 1W20C perfluoroalkyl group, aWl is a positive number and 1.9≤a+b+c≤2.2.
