Claim Text:
1. An antifoam composition, based upon total antifoam composition weight, said antifoam composition comprises: a) about 35% to about 75% of an organomodified silicone comprising one or more 2-phenylpropylmethyl moieties, and no more than 75 mole percent 2-phenylpropylmethyl moieties b) from about 2% to about 8% of silica; c) 10% or greater of a siloxane polymer based on the weight of said organomodified silicone, said siloxane polymer having a viscosity of from about 0.5 cSt to about 10,000 cSt said siloxane polymer having a viscosity that is 5% up to 99% of the viscosity of said organomodified silicone; d) from about 1.5% to about 4.0% of a silicone resin; and e) from 0% to about 10% of solvent; said antifoam composition having a viscosity, at a shear rate of 20 sec
