    • Disclosed is a composition comprising a crosslinked product of a liquid composition which comprises (a) a fluorosilicone, (b) a crosslinking agent and (c) a thermal stabilizing agent comprising a reaction product of (i) a cyclic unsaturated-alkyl-group-substituted polyorganosiloxane, (ii) a linear unsaturated-alkyl-group-substituted polyorganosiloxane, and (iii) a metal acetylacetonate or metal oxalate compound. The crosslinked fluorosilicones can be employed as intermediate or outer layers of electrostatographic fuser members, electrostatographic intermediate transfer belt materials and the like. They are useful in applications wherein materials possessing desirable release characteristics, surface energies, electrical characteristics, oil resistance properties, or solvent resistance properties exhibited by fluorosilicone elastomers are desirable. They are also useful in applications wherein fluorosilicones are exposed to high temperatures, since the stabilizing components reduce the generation of toxic effluents such as trifluoropropionaldehyde and formaldehyde, which can form when methyl-methyl crosslinking of the polymer occurs, and increase temperature stability.
    • 公开了包含液体组合物的交联产物的组合物,其包含(a)氟硅酮,(b)交联剂和(c)热稳定剂,其包含以下反应产物:(i)环状不饱和烷基 - 取代的聚有机硅氧烷,(ii)线性不饱和烷基取代的聚有机硅氧烷,和(iii)金属乙酰丙酮化物或金属草酸盐化合物。 交联氟硅氧烷可以用作静电定影部件,静电中间转印带材料等的中间或外层。 它们可用于其中具有期望的释放特性,表面能,电特性,耐油性能或由氟硅氧烷弹性体显示的耐溶剂性能的材料。 它们也可用于将氟硅氧烷暴露于高温的应用中,因为稳定组分可减少有机污染物的产生,例如三氟丙醛和甲醛,当聚合物发生甲基 - 甲基交联时可形成,并提高温度稳定性。
