  • Retroflective articles including a cured ceramer composite coating having abrasion and stain resistant characteristics
    Patent number: 6265061
    Abstract: 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.

  • Retroreflective articles including a cured ceramer composite coating having a combination of excellent abrasion, dew and stain resistant characteristics
    Patent number: 6132861
    Abstract: 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.
