Abstract: The composition includes a curable fluoropolymer having nitrogen-containing cure sites and a curative including an organo onium cation and an anion represented by Formula (I) or Formula (II). The composition is free of metal cations or has not more than 20 parts per million metal cations and free of silicon dioxide or has less than 0.5 percent by weight silicon dioxide, based on the total weight of the composition. In some cases, the composition consists of the curable fluoropolymer and the curative. Shaped articles including the composition, a fluoroelastomer prepared by curing the composition, a method of making a fluoroelastomer article, and a process for making the composition are also described.
