Quick Cure 300 is a high purity mixture of nitrate and nitrite salts, formulated specifically for curing extruded rubber profiles in the lowest possible temperature range. It is used as a molten liquid salt. It is especially effective at curing silicone profiles and sponge rubber in the 380 – 475°F. range. Quick Cure 300 can be used to cure conventional rubber profiles at higher temperatures (over 400°F). It is a high purity mixture with a relatively sharp melting point yielding low viscosity and high fluidity at any operating temperature.
