STABILE ALKYLWASSERSTOFFPOLYSILOXAN- EMULSIONEN

An aqueous alkylhydridopolysiloxane emulsion is stabilized against loss of hydrogen by addition thereto of about 0.1 to 5% by weight of an emulsifier containing perfluoroalkyl groups. The emulsion may further contain a fluoroalkyl-substituted siloxane of the formula wherein R each independently is a...

More Information
Summary:An aqueous alkylhydridopolysiloxane emulsion is stabilized against loss of hydrogen by addition thereto of about 0.1 to 5% by weight of an emulsifier containing perfluoroalkyl groups. The emulsion may further contain a fluoroalkyl-substituted siloxane of the formula wherein R each independently is alkyl with 1 to 6 carbon atoms or phenyl, RF is fluoroalkyl with 4-12 carbon atoms, a is about 5 to 70, and b is about 5 to 70. Advantageously the emulsifier is a member selected from the group consisting of a perfluoroalkyl ether of the formula CxF2x+1SO2N (CH3) CO-(OCH2-CH2)n-(OCH CH3CH2)m-OC4H9, wherein X=about 6-12, n=2-about 40 and m=2-about 40, and a perfluorinated alkane sulphonic acid salt of the formula CxF2x+1SO3N(CnH2n+1)4 wherein x=6-12 and n=1-3.
