Parquench® 90

Description

‍

PARQUENCH® 90 is a unique water based polymer quenchant. It is far superior to oil in its safety and environmental characteristics. Unlike polyalkylene glycols, PARQUENCH® 90 is completely water soluble at all concentrations and temperatures. It is non-flammable, non-toxic, and provides desirable cooling characteristics, more reliable control in use, minimal environmental impact, and better economy.

‍

PARQUENCH® 90 can provide cooling rates at all stages of quenching that approximate those exhibited by fast quench oils. Consequently, those conditions necessary for achieving maximum hardness in steel with minimum distortion or cracking can be realized.

‍

PARQUENCH® 90 is widely used for quenching forgings in open tanks. It can be used in continuous furnaces.

Key Properties

• A water-based polymer quenchant noted for its safety and environmental friendliness compared to oil-based quenchants. It is non-flammable, non-toxic, and fully soluble in water at all concentrations and temperatures. This product offers cooling rates similar to fast quench oils, enabling maximum hardness in steel with minimal distortion or cracking.
• Appears as a slightly hazy, straw-colored liquid. It has a viscosity of 130 cSt at 40°C, a freezing point of -4°C, and a pH of 9.0. Its specific gravity is 1.03, and it features a refractometer factor of 8.3, indicating its relative density compared to water.
• Can be used at concentrations ranging from 1% to 40% by volume, and is effective in temperatures from ambient to 60°C. It is suitable for use in various settings, including open tank quenching and continuous furnaces, and requires significant agitation (greater than 0.5 m/s) for optimal results.
• Contains a corrosion inhibitor that can be supplemented with RUST INHIBITOR SQ if necessary, to enhance its anti-corrosion properties.
