Partially-fluorinated silane bonding agent

An article comprising a first composition comprising a fluoropolymer, a second composition comprising a silicone polymer, wherein the second composition is bonded to the first composition, and a partially-fluorinated silane bonding agent according to Formula I:

• X—Rf—(O)p—(CH2)m—Si—Y3 (I)
• wherein:
• X is CH2═CH—, CH2═CHCH2—, CH2═CHCH2—O—, or CF2═CF—O—;
• Rf is a perfluoro(alkylene) group having 1 to 8 carbon atoms and, optionally, at least one catenary heteroatom selected from the group consisting of O and N;
• m is an integer from 2 to 5;
• p is 0 or 1;
• and
• Y is —Cl or —OR, where R is a linear or branched alkyl having 1 to 4 carbon atoms.
