Abstract
A ceramer composition is provided that comprises a plurality of colloidal inorganic oxide particles and a free-radically curable binder precursor. The free-radically curable binder precursor comprises a fluorochemical component that further comprises at least two free-radically curable moieties and at least one fluorinated moiety. By virtue of the inclusion of the fluorochemical component, the ceramer compositions of the present invention can be used to provide ceramer composites and ceramer composite structures with excellent stain, oil and/or water repellency characteristics as well as a high level of abrasion resistance and hardness.
