Abstract
An antifoaming agent including: (A) an organopolysiloxane having a hydrolysable group shown by the formula (1) on at least one silicon atom of an organopolysiloxane segment constituting a main chain and containing siloxy units shown by the formula (2) at an amount of at least 10 mol % of the total, (B) a non-linear organosilicon resin other than the organopolysiloxane of component (A); and (C) a hydrophobic filler, and a method for manufacturing thereof. (where X represents a divalent hydrocarbon group having 1 to 10 carbon atoms; and R each independently represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 4 carbon atoms) (where Rrepresents a monovalent hydrocarbon group having 1 to 12 carbon atoms; and Rrepresents an organic group having an aryl group and 6 to 12 carbon atoms, optionally containing an oxygen atom or a halogen atom)
