ABSTRACT:
The invention covers an antiwetting composition for imparting hydrophobic properties onto fabrics and fibrous substrates, as well as a method for producing a hydrophobic article. The composition of the present invention includes a dispersion of polymeric fluoroaliphatic ester and a silicone resin prepolymer in a water-based carrier. The polymeric fluoroaliphatic ester is included in the dispersion at about 0.12 to 0.5 percent solids by weight. The silicone resin prepolymer is generally a polysiloxane having silanol terminal groups. The silicone compound is added to the dispersion in a range of about 0.08 to about 0.34 percent solids by weight. The components are impregnated in a fiber substrate and subsequently cured to provide an article having improved hydrophobic properties over known antiwetting compositions.
