It is suitable for all-year-round usage in automotive and commercial petrol and diesel engines, as well as certain industrial applications. The coolant must be diluted before use; for example, a 50/50 mix provides -40°C freezing protection. It is an ethylene glycol-based engine coolant concentrate and is nitrite, amine, and phosphate (NAP) free, featuring superior silicate stabilisation technology.
