Abstract
A pressure roll that forms a fusing nip with a fuser roll in a fusing system has a core and a surface coating having been heat cured from a composition of a fluorocarbon polymer and an irregularly shaped, nonplanar, inert filler having a hardness greater than 8 Mohs, the filler having a nominal particles size of from about 10 to 30 microns and being present in the cured surface coating in an amount of from about 10% to 40% by weight of the total solids weight of the coating.
Claims17
A pressure roll that forms a fusing nip with a fuser roll in a fusing system, said pressure roll comprising a core and a surface coating having been heat cured from a composition comprising a liquid fluorocarbon polymer and an irregularly shaped, nonplanar, inert filler having a hardness greater than 8 Mohs, said filler having a nominal particle size of from about 10 to 30 microns and being present in said cured surface coating in an amount of from about 10% to 40% by weight of the total solids weight of the coating.
A fusing system comprising a heated fuser roll and a backup pressure roll forming a fusing nip therewith for fusing a toner image to a substrate, said pressure roll comprising a core and a surface coating having been heat cured from a composition comprising a liquid fluorocarbon polymer and an irregularly shaped, nonplanar, inert filler having a hardness greater than 8 Mohs, said filler having a nominal particle size of from about 10 to 30 microns and being present in said cured surface coating in an amount of from about 10% to 40% by weight of the total solids weight of the coating.
