Abstract
A fuser member having a support metallic core and a layer of material formed over the metallic core, an intermediate layer, and an outer layer, the intermediate layer including a cross-linked poly(dialkylsiloxane); one or more multifunctional silanes; one or more amino functional silane crosslinking agents; catalyst; and optional fillers.
Claims15
A fuser member having, in order, a support metallic core and a layer of material formed over the metallic core;
- an intermediate layer;
- and an outer layer;
- wherein the intermediate layer is a material comprising:
- (a) a crosslinkable poly(dialkylsiloxane);
- (b) one or more multifunctional silanes;
- and
- (c) one or more amino functional silane crosslinking agents comprising a silicon atom that is bonded to at least one group that contains a primary amino or secondary amino group.
A fuser member having a support metallic core and a layer of material formed over the metallic core, an intermediate layer, and an outer layer, wherein the intermediate layer is a material comprising:
- (a) a crosslinkable poly(dialkylsiloxane), wherein the poly(dialkylsiloxane) has a weight average molecular weight before crosslinking above 5,000;
- (b) a silane crosslinking agent;
- and
- (c) one or more amino functional silane crosslinking agents being present in an amount less than 15 parts based on 100 parts of poly(dialkylsiloxane);
- the amino functional silane comprises a silicon atom that is bonded to at least one group that contains a primary amino or secondary amino group and is represented by the following structure:
- where R is an alkyl group having 1 to 7 carbon aroms, R′ is an alkyl group having 1 to 7 carbon atoms or a polyalkoxyalkyl group of less than 7 carbon atoms;
- Y is an amino group or an amino substituted alkyl group, or a polyaminosubstituted alkyl or an alkenylalkoxy amino or an aryl amino group of less than 15 carbon atoms, and h is 1 to 3, b is 0 to 2, q is 1 or 2 and h+b=3.
