Water Soluble Polymer Quenchant
Description
Castrol Iloquench™ 700 Aqua is a polymer quenchant for Induction Hardening of steel and cast iron.

It's an aqueous solution of synthetic water-soluble polymers of high molecular weights with the addition of an antifoam agent and nitrite free corrosion inhibitors.

Iloquench 700 Aqua has low residue and reduced dragout characteristics.

Application
Iloquench 700 Aqua has been developed for quenching of steel components in induction or flame hardening applications to reduce the occurence of warping or cracks.

Typical components treated are crankshafts, gears, axles, transmission shafts, saw blades, rolling mill cylinders, rocker arms and push rods. Iloquench 700 Aqua offers a rate of quench which is intermediate between water and oil, which can be varied by altering
the concentration.

Conditions of Use
The quenching result is affected by many parameters, such as the metal alloy and and the geometry of the part, the required depth of effective quenching and the method of application.
It is recommended to perform preliminary tests on the unit under consideration for optimising the process parameters.
Temperature of bath: 20 - 45 °C
Typical concentrations: - Carbon steel and low alloy steel 5 - 10%
- Medium alloy steel 10 - 15%
- High alloy steel 15 - 25%

Advantages
Non flammability of quenching bath, reduce the risk of fire hazards.
Excellent in process corrosion protection.
Low foaming.
Improved conditions of work - elimination or considerable reduction of deposits on handling machines and
quenched work.
Improved cleanability.
Reduced drag out and residue formation.
RENAULT approval: 4521057700.
