About 0.01% to 10% of an antifoam silicone oil having a predetermined viscosity of at least about 100 cp is dispersed in an aqueous solution of a water-soluble gum having a viscosity within about 20% of the predetermined viscosity of the silicone oil. A substrate is contacted with the dispersion so as to form a dispersion-wetted substrate and at least a part of the aqueous solution is removed from the substrate, wherein the silicone oil remains in the substrate.
