Abstract

A fuser fluid composition is disclosed, including a non-fluorinated functional silicone fluid, and a non-fluorinated non-functional silicone fluid, where the non-fluorinated functional silicone fluid is present in the fuser fluid composition in an amount of from about 1 wt % to about 30 wt % based on a total weight of the fuser fluid composition, and the non-fluorinated non-functional silicone fluid is present in the fuser fluid composition in an amount of from about 50 wt % to about 99 wt % based on a total weight of the fuser fluid composition. The non-fluorinated functional silicone fluid may include an amine-functional group. A cleaning web and a fusing subsystem for a printing system may include a material impregnated with the fuser fluid composition.

Claims (40)

1. A fuser fluid composition, comprising:

a non-fluorinated functional silicone fluid; and

a non-fluorinated non-functional silicone fluid; and wherein:

the non-fluorinated functional silicone fluid is present in the fuser fluid composition in an amount of from about 1 wt % to about 30 wt % based on a total weight of the fuser fluid composition;

the non-fluorinated non-functional silicone fluid is present in the fuser fluid composition in an amount of from about 50 wt % to about 99 wt % based on a total weight of the fuser fluid composition; and

the non-fluorinated non-functional silicone fluid comprises a chemical structure of:

2. The fuser fluid composition of claim 1 , wherein n is from about 100 to about 10000.

3. The fuser fluid composition of claim 1 , wherein the non-fluorinated functional silicone fluid comprises an amine-functional group.

4. The fuser fluid composition of claim 1 , wherein the non-fluorinated functional silicone fluid comprises a chemical structure of:

5. The fuser fluid composition of claim 4 , wherein n is from about 100 to about 10000.

6. The fuser fluid composition of claim 4 , wherein m is from about 100 to about 1000.

7. The fuser fluid composition of claim 1 , wherein a viscosity of the fuser fluid composition is from about 10 to about 10,000 cP.

8. The fuser fluid composition of claim 1 , wherein:

the non-fluorinated functional silicone fluid is present in the fuser fluid composition in an amount of 10 wt % based on a total weight of the fuser fluid composition; and

the non-fluorinated non-functional silicone fluid is present in the fuser fluid composition in an amount of 90 wt % based on a total weight of the fuser fluid composition.

9. The fuser fluid composition of claim 1 , wherein a ratio of the non-fluorinated non-functional silicone fluid to the non-fluorinated functional silicone fluid is from about 7 to about 10.

10. A cleaning web for a printing system, comprising a material impregnated with the fuser fluid composition of claim 1 .

11. A cleaning web for a printing system, comprising:

a material impregnated with a fuser fluid composition; and

a backer roll configured to form a compliant nip between the material and a fuser roll; and

wherein the fuser fluid composition comprises:

a non-fluorinated functional silicone fluid present in the fuser fluid composition in an amount of 90 wt % based on a total weight of the fuser fluid composition; and

a non-fluorinated non-functional silicone fluid present in the fuser fluid composition in an amount of 10 wt % based on a total weight of the fuser fluid composition; and

the non-fluorinated non-functional silicone fluid comprises a chemical structure of:

12. The cleaning web for a printing system of claim 11 , wherein the non-fluorinated functional silicone fluid comprises an amine-functional group.

13. The cleaning web for a printing system of claim 11 , wherein the non-fluorinated functional silicone fluid comprises a chemical structure of:

14. A fusing subsystem for a printing system, comprising:

a fuser roll, comprising a silicone layer disposed on a core and a topcoat comprising a fluoropolymer disposed onto the silicone layer;

a cleaning subsystem comprising:

a material impregnated with a fuser fluid composition; and

a backer roll configured to form a compliant nip between the material and a fuser roll; and

wherein the fuser fluid composition comprises:

a non-fluorinated functional silicone fluid present in the fuser fluid composition in an amount of 90 wt % based on a total weight of the fuser fluid composition; and

a non-fluorinated non-functional silicone fluid present in the fuser fluid composition in an amount of 10 wt % based on a total weight of the fuser fluid composition; and

the non-fluorinated non-functional silicone fluid comprises a chemical structure of:

15. The fusing subsystem for a printing system of claim 14 , wherein the non-fluorinated functional silicone fluid comprises a chemical structure of:

16. The fusing subsystem for a printing system of claim 15 , wherein:

n is from about 100 to about 10000; and

m is from about 100 to about 1000.

17. The fusing subsystem for a printing system of claim 14 , wherein a viscosity of the fuser fluid composition is from about 10 to about 10,000 cP.
