DESCRIPTION Quick Cure 275 is a high purity, eutectic mixture of nitrate and nitrite salts, formulated specifically for curing extruded rubber profiles at the lowest possible temperature ranges. It is used as a molten liquid salt bath and is especially effective for curing silicone profiles and sponge rubber in the 325-475oF. range and can also be used to cure conventional rubber profiles at higher temperatures (over 400oF). Because it is a high purity mixture with a low, sharp melting point it is very fluid at any operating temperature. There are a number of important reasons for curing rubber with Quick Cure 275:
It is chemically stable over its wide operating temperature range.
The free flowing characteristics of the salt assure virtually no lumping or caking problems.
It can be used with wide operating temperature variations - 315-650oF.
The salt bath, when heated, maintains its viscosity at operating temperatures.
Rubber profiles, when immersed in the Quick Cure 275 salt bath, will retain their shape, without sagging or distortion, with uniform surface cure, minimizing scrap.
