Abstract
Provided is composition for a liquid coating. The composition may include a silanol terminated copolymer, at least one cross-linker, and a catalyst. The silanol terminated copolymer may include from about 10 to about 25 mol % of a diphenylsiloxane repeat unit and greater than about 50 mol % of a dialkylsiloxane repeat unit. The at least one cross-linker may be one or more selected from: tetraethoxysilane (TEOS), a trialkoxysilane terminated polydialkylsiloxane and/or one or more of a trialkoxysilyl terminated polymer.

1 more element
A transfix blanket for a printer, comprising:
- a substrate layer;
- and
- a topcoat layer disposed on the substrate layer, wherein the topcoat layer comprises a silanol terminated copolymer crosslinked with at least one cross-linker,
- wherein the silanol terminated copolymer comprises from about 10 to about 25 mol % of a diphenylsiloxane repeat unit and greater than about 50 mol % of a dialkylsiloxane repeat unit, wherein the silanol terminated siloxane copolymer is represented by:
- where R is a linear, branched, or cyclic saturated or unsaturated alkyl group containing from about 1 to 30 carbon atoms and s is from about 1 to about 500 and t is from about 1 to about 300, and
- wherein the at least one crosslinker comprises at least one selected from the group consisting of tetraethoxysilane (TEOS), a trialkoxysilane terminated polydialkylsiloxane and one or more of a trialkoxysilyl terminated polymer.
