Curing agents for compounds

Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile-containing cure site monomer are cured with certain hydrazone or oxime curatives.

Curable fluoroelastomer composition

A fluoroelastomer compound comprising at least one co-agent and at least one chemical entity comprising: (1) an azo functional group or (2) an oxazoline functional group, when cured into an article using a peroxide curing agent, the article exhibits no visible particles on the article surface when viewed at a magnification of 500 times that of an unmagnified image.
