NuQuench Oil 3440: Is a fast quench oil that imparts maximum hardness to low carbon and alloys steels. Provides uniform cooling for tightly packed parts and  minimal drag-out.

NuQuench Oil 3310: Is a fast oil that provides high harness values to low carbon and alloy steels. Special additive technology provides long life, reduced drag-out and uniform hardness to tightly packed parts.

NuQuench Oil K900: This very fast oil provides maximum hardness to low carbon and alloy steels. The low viscosity oil allows for uniform quenching of shapes and tightly packed parts.

NUQUENCH POLYMER QUENCHANTS

Polymer cooling response 4

NUQUENCH A Is a nonflammable, aqueous solution containing polymers and corrosion inhibitors. It’s designed for quenching ferrous and nonferrous materials in a variety of geometrical shapes. NuQuench A can replace water, oil or brine solutions and is a preferred quenching media for low and high hardenability steels.

PAG POLYMER QUENCHANTS: Nutech offers a complete line of PAG polymer quenchants for a variety of heat treating applications. These water soluble polymer quenchants offer reduced fire hazards and cooling responses similar to oil quench.

PEG POLYMER QUENCHANT: This unique polymer quench has regular solubility for clean operation.

PVP POLYMER QUENCHANTS: This line of polymer quench is economical and offerrs cooling responses similar to quench oil.

RUBBER CURING SALTS

NUQUENCH 275 RCS 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 325-475 F. range and can also be used to cure conventional rubber profiles at higher temperatures (over 400 F). 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 NUQUENCH 275 RCS.
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  315-650 F.
The salt bath, when heated, maintains its viscosity at operating temperatures.
