Abstract

Provided is a polymer coating composition for a surface layer, comprising a product of a grafting reaction between a fluoroelastomer and at least one of an aminosilane component and an aminofunctionalized fluorosilicone component.

First claim

What is claimed is:

1. A polymer coating composition for a surface layer, comprising:
a product of a grafting reaction between a fluoroelastomer and at least one of an aminosilane component and an aminofunctionalized fluorosilicone component,
wherein the aminosilane component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph, and
wherein the aminofunctionalized fluorosilicone component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph.

2. The composition of claim 1 , wherein the reaction product is crosslinked.

3. The composition of claim 1 , wherein the aminosilane component comprises an oxyaminosilane.

4. The composition of claim 3 , wherein the oxyaminosilane is represented by formula (1):
Si(OR) p R′ q (-L-NH 2 ) 4-p-q   (1),

where R is hydrogen or alkyl, p is an integer from 1 to 3, R′ is an alkyl, q is an integer from 0 to 2, L is a linking group, and 4-p-q is at least 1.

5. The composition of claim 1 , wherein the aminofunctionalized fluorosilicone component comprises an am inofunctionalized alkoxy-terminated fluorosilicone.

6. The composition of claim 5 , wherein the aminofunctionalized alkoxy-terminated fluorosilicone is represented by formula (2):

7. A printing system comprising:
an imaging member comprising a substrate and a surface layer disposed on the substrate, wherein the surface layer comprises a cured product of a grafting reaction between a fluoroelastomer and at least one of an aminosilane component and an aminofunctionalized fluorosilicone component,
wherein the aminosilane component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph, and wherein the aminofunctionalized fluorosilicone component is present in an amount relative to an amount of the fluoroelastomer of about 2 pph to about 10 pph.

8. The printing system of claim 7 , wherein a the surface layer is a topcoat of a fuser subsystem.

9. The printing system of claim 7 , wherein the surface layer is a topcoat of blanket for an aqueous transfix printing system.

10. The printing system of claim 7 , wherein the surface layer is a reimageable surface layer of a digital printing system.
