  • Utensil and use of a sol gel coating on such a utensil
    Publication number: 20050260421
    Abstract: As the chemical resistance of sol gel based coatings is superior to that of regular decorative coatings based on organic material, sol gel coatings are generally very well suited to serve as coatings that are exposed to cosmetic formulations, such as lotions and shampoos. The invention relates to a utensil which is provided with a sol gel coating comprising an organosilane compound that has been fluorinated. The invention also relates to the use of such a sol gel coating on a utensil.
