Zinc peroxide (ZnO2) is a chemical compound used as a bleaching and curing agent. Perhaps its most important use is to promote cross-linking in carboxylated nitrile rubber and other elastomers.[1]
Conditions/substances to avoid are: water, acids, salts of heavy metals, reducing agents, organic materials, flammable substances and hydrogen peroxide.
