Parcure 275 An eutectic mixture offering the lowest possible melt point and the widest working range. (275 Parkettes)

Parcure 290 An eutectic mixture with slightly higher melt point and narrower working range but lower in cost than Parcure 275. (290 Parkettes)

Parcure 305 A very popular rubber cure salt that combines wide working range with low cost and relatively lower dragout when used above 400°F. (330 Parkettes)

Parcure 300 A nitrite-free alternative for customers concerned with the introduction of nitrosamines from the alkali nitrite raw materials used in the production of commercial rubber cure salts. Within its working range, Parcure 300 exhibits viscosities less than or equal to more conventional salts now used; so resultant dragout could be less.
