Compositions include a curing agent of a fluorinated resorcinol or hydroquinone of Formula 1:R1 and R5 are independently H, halogen, optionally partially or fully halogenated C1-18 alkyl, optionally partially or fully halogenated C1-18 alkoxy, or X. R2-R4 are independently OH, H, halogen, optionally partially or fully halogenated C1-18 alkyl, optionally partially or fully halogenated C1-18 alkoxy, or X. At least one of R2, R3, and R4 is OH. Not more than 3 of R1-R5 are halogen. X is Formula 2 or Formula 3 as disclosed herein. Curable fluoroelastomer compositions, fluoroelastomer masterbatches, curing agent and curing accelerator mixtures, salts, and methods of curing a polyhydroxy-curable fluoroelastomer including a curing agent of a fluorinated resorcinol or hydroquinone of Formula 1 are also disclosed herein.
