1. A curable composition comprising a fluoroelastomer comprising a nitrogen-containing cure site monomer and a curative selected from the group consisting of curatives of Formula I and II, where Formula I is: wherein each R1 is independently selected from H, Cl, Br, I, a C1 to C20 linear, cyclic, or branched alkyl group, a C5 to C20 aryl group, a C5 to C20 alkaryl group, a C5 to C20 aralkyl group, and NH2; each R2 is —OH; each R3 is independently selected from H, Cl, Br, I, a C1 to C20 linear, cyclic, or branched alkyl group, a C5 to C20 aryl group, a C5 to C20 alkaryl group, a C5 to C20 aralkyl group, and NH2; each R4 is independently selected from H, Cl, Br, I, a C1 to C20 linear, cyclic, or branched alkyl group, and a C5 to C20 aryl group, a C5 to C20 alkaryl group, a C5 to C20 aralkyl group; each R5 and R6 is independently selected from an —H, a C1 to C20 linear or branched alkyl group, a C3 to C40 alkyl group that forms a spiro group when both R5 and R6 are part of the same cyclic structure, a C5 to C40 aryl group, a C5 to C40 alkaryl group, a C5 to C40 aralkyl group that optionally forms a spiro group when both R5 and R6 are part of the same cyclic structure, an —OH, and together with one another a C═O; provided that at least one of R1 and R3 on each ring is an —NH2; and Formula II is: wherein each R1 is independently selected from H, Cl, Br, I, a C1 to C20 linear, cyclic, or branched alkyl group, a C5 to C20 aryl group, a C5 to C20 alkaryl group, a C5 to C20 aralkyl group, and NH2; each R2 is —OH; each R3 is independently selected from H, Cl, Br, I, a C1 to C20 linear, cyclic or branched alkyl group, a C5 to C20 aryl group, a C5 to C20 alkaryl group, a C5 to C20 aralkyl group, and NH2; each R4 is independently selected from H, Cl, Br, I, a C1 to C20 linear, cyclic or branched alkyl group, a C5 to C20 aryl group, a C5 to C20 alkaryl group, and a C5 to C20 aralkyl group; each R5 is independently selected from an —H, a C1 to C20 linear, cyclic, or branched alkyl group, a C5 to C40 aryl group, a C5 to C40 alkaryl group, and a C5 to C40 aralkyl group; provided that at least one of R1 and R3 on each ring is an —NH2. |
