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 utilization 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.
