Development of an Anhydrous Coolant for Automotive Applications 900432

An anhydrous coolant based on propylene glycol has been developed by DOW CHEMICAL CANADA INC. Formulated specifically for automotive cooling needs, its development involved standard ASTM corrosion testing as well as actual fleet testing. This anhydrous coolant, though not commercially available, presently meets or exceeds the current corrosion performance characteristics of present ethylene glycol based automotive coolants. Performance data accumulation from existing fleet service is ongoing and indicates satisfactory results. The latter service testing will be brought to a conclusion at a later date.
