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.

Ceramer composition and composite comprising free radically curable fluorochemical component

A sporting goods article with a coating on a surface of the article for abrasion resistance and/or a high gloss appearance. The outer layer of the surface is a polymer, wood, metal, non-polymeric ink, non-polymeric colorant, non-polymeric dye, or a combination thereof The coating is a cured ceramer composition. The cured ceramer composition, in its simplest embodiment, is derived from a composition including inorganic oxide particles and a curable organic matrix, with the curable organic matrix including at least one ethylenically unsaturated monomer and at least one organofunctional silane monomer coupling agent.

Sporting goods having a ceramer coating

A curable ceramer composition, coated articles and methods for making and curing the composition. The curable ceramer comprises a fluoro/silane, a crosslinkable silane, a curable binder precursor, and a colloidal inorganic oxide. The ceramer has a long shelf life before cure and can be used to provide cured ceramer coatings and articles having stain resistance, abrasion resistance and hardness.

Ceramer composition incorporating fluoro/silane component and having abrasion and stain resistant characteristics

A retroreflective article comprising a substrate and a cured ceramer coating provided on at least a portion of a surface of the substrate. The coated portion of the surface is retroreflective and can be dew-resistant. The ceramer is derived from a free-radically-curable binder, colloidal inorganic oxide and fluoro/silane component comprising a hydrolyzable silane moiety and a fluorinated moiety.

Retroflective articles including a cured ceramer composite coating having abrasion and stain resistant characteristics

A retroreflective article comprising a substrate and a cured ceramer coating provided on at least a portion of a surface of the substrate. The coated portion of the surface is retroreflective. The coating comprises a cured ceramer composite derived from ingredients comprising a free radically curable binder precursor and a plurality of surface treated, colloidal inorganic oxide components. The colloidal inorganic oxide components are surface treated with a surface treatment agent comprising a fluoro/silane component comprising a hydrolyzable silane moiety and a fluorinated moiety, and a crosslinkable silane component comprising a hydrolyzable silane moiety and a free radically crosslinkable moiety. The weight ratio of the crosslinkable silane component to the fluoro/silane component is from about 4:1 to 20:1, and the weight ratio of the free radically curable binder precursor to the colloidal inorganic oxide components is from about 1:10 to 8:10. A method of making a retroreflective article by coating a substrate with a ceramer composite coating is also described. A method of making a dew-resistant retroreflective article by coating a substrate with a ceramer composite coating and then surface treating the coating is also described.
