METALGUARD® A85

Heavy-Duty, Nitrite Free Extended Life Antifreeze Inhibitor

25+ years in coolant additives|Decades of chemical expertise| Global manufacturing and distribution

METALGUARD A85 is the latest generation of coolant chemistry developed specifically for heavy-duty applications requiring ethylene glycol-based, extended life coolant with OAT technology. METALGUARD A85 was developed for superior performance and durability under the more demanding engine operating conditions. It has higher temperature stability and excellent heat transfer properties for applications like CNG (Compressed Natural Gas), EGR (Exhaust Gas Recirculation) and SCR (Selective Catalytic Reduction) systems. It can be used in all types of heavy-duty engines and is excellent for light-duty and automotive service.

As an all-organic formulation, METALGUARD A85 does not contain any conventional inorganic salts (nitrite, nitrate, silicate, phosphate and borate), amines or 2-ethylhexanoic acid. The technology minimizes deposit formation, protects all types of metals, has high compatibility with non-metal components (hoses, seals, and gaskets), and provides outstanding cylinder liner cavitation/pitting protection.

With a formal heavy-duty engine coolant maintenance program, the coolant can deliver cooling system protection for up-to 1,000,000 miles of on-road use (8 years or 20,000 hours of off-road use) without the use of standard Supplemental Coolant Additives (SCAs). Through laboratory testing, and if required, a concentrated booster is available for restoring the inhibitor content to keep the coolant in proper balance.
