Abstract:
A free-radically curable ceramer composition comprising:(a) a plurality of colloidal inorganic oxide particles wherein said colloidal inorganic oxide particles are surface treated with a surface treatment agent comprising a curable fluoro/silane component of the formula: (Sv)râ€”Wâ€”(Rf)sâ€ƒâ€ƒ(7) â€ƒwherein each Sy independently is a hydrolyzable silane moiety, â€ƒeach Rf is defined by the formula CnF2+1, where n is 3 to 20 and one or more non-adjacent â€”CF2â€” groups may be replaced by oxygen, â€ƒr is at least 1, s is at least 1, and â€ƒW is a linking group having r+s valent sites, and (b) a free-radically curable binder precursor, wherein said free-radically curable binder precursor comprises a free-radically curable fluorochemical component comprising at least two free-radically curable moieties and at least one fluorinated moiety.
