  • Patent number: 7723417
    Abstract: The present invention provides an aqueous composition comprising (i) a fluorochemical compound and (ii) an ester derivative of an alpha-hydroxy acid, the ester derivative having a melting point of not more than 35° C. and a water solubility of not more than 10% by weight at 25° C. The fluorochemical compound is typically dispersed or emulsified in the aqueous composition. The aqueous compositions may provide such advantages as providing good oil- and/or water repellency properties to a substrate upon application at ambient conditions, without the need for a heat treatment. Thus, the aqueous compositions may be used to provide oil- and/or water repellency properties to a substrate such as for example a fibrous substrate, e.g., leather or textile. In particular, repellency properties comparable to those achieved with a heat treatment step may be achieved.

  • Patent number: 7611752
    Abstract: A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.
