Excellent resistance to oxidation and thermal changes allowing repeated quenchings owing to:

- the use of solvent-refined base oils,

- the presence of effective and durable antioxidant additives which give long bath life.

High flash point to ensure risk-free operation in the utilisation temperature range.

Low volatility limits evaporation loss and the formation of vapours and fumes.

Effective, durable cooling powers guarantee mechanical properties achieved after quenching (hardness, depth of hardness).

Low fluidity at the temperature of use reduces loss by entrainment, resulting in product savings.

Good antifoam properties which are essential on account of the high swirling of oil in the hardening tanks.
