Abstract
This invention provides a fuser belt comprising a substrate and a coating on said substrate, said coating comprises a resin made by curing a composition comprising siloxanes having a ratio of difunctional to trifunctional units of 1:1 to 1:2.7 and at least 90% of total number of functional units in said siloxanes are difunctional and trifunctional units, a weight average molecular weight of 5,000 to 50,000 grams/mole, and an alkyl to aryl ratio of 1:0.1 to 1:1.2.

A fuser belt comprising a substrate and a coating on said substrate, said coating comprises a resin made by curing a composition comprising siloxanes having a ratio of difunctional to trifunctional units of 1:1 to 1:2.7 and at least 90% of total number of functional units in said siloxanes are difunctional and trifunctional units, a weight average molecular weight of 5,000 to 50,000 grams/mole, and an alkyl to aryl ratio of 1:0.1 to 1:1.2.
A fuser belt comprising a substrate and a coating on said substrate, said coating comprises a resin made by curing a composition comprising siloxanes having a ratio of difunctional to trifunctional units of 1:1.8 to 1:2.3 and at least 98% of total number of functional units in said siloxanes are difunctional and trifunctional units, a weight average molecular weight of 7,500 to 8,500 grams/mole, and an an alkyl to aryl ratio of 1:0.4 to 1:0.9.
A method of fusing comprising the steps of:
- passing a receiver bearing toner through the nip formed between a fuser belt and a roller to form a fixed toner image on said receiver, said fuser belt comprising a substrate and a coating on said substrate, said coating comprises a resin made by curing a composition comprising siloxanes having a ratio of difunctional to trifunctional units of 1:1 to 1:2.7 and at least 90% of total number of functional units in said siloxanes are difunctional and trifunctional units, a weight average molecular weight of 5,000 to 50,000 grams/mole, and an alkyl to aryl ratio of 1:0.1 to 1:1.2;
- cooling said fuser belt in contact with said fixed toner image on said receiver;
- and
- releasing said fixed toner image on said receiver from said fuser belt.
