METALGUARD® A80

METALGUARD A80 is Poly-Organic/Multi-Organic additive package that allows you to make antifreeze meeting ASTM D6210, as well as ASTM D3306 and ASTM D4985. It contains no amine, phosphate, silicate, borate, nitrate, nitrite, or 2-ethylhexanoic acid. METALGUARD A80 meets the performance requirements of ASTM D6210 without nitrite or nitrite/molybdate, but still provides wet sleeve cylinder liner cavitation protection due to its unique formulation. A major advantage of this type of additive system is that it provides total cooling system protection for 600,000 on-road miles without the use of additive-containing coolant filters or supplemental coolant additives (SCAs). The addition of a METALGUARD A80 extender at 300,000 miles, if needed, is the only maintenance recommended, although, it is recommended that a sample of the coolant be inspected quarterly to detect any problems such as significant color change, pH change, phase separation, precipitation, cloudiness, or obvious contamination. With the same maintenance program, A80 will provide protection for 12,000 hours or 6 years whichever comes first.

METALGUARD A80’s all organic formulation also has several other advantages. It is compatible with most types of coolant technologies including conventional inorganic acid salt formulations, most straight organic acid (OAT) formulations, hybrid organic acid formulations (HOAT), nitrited OAT formulations (NOAT) and other multi-organic acid formulations. Antifreeze/ coolant made with METALGUARD A80 is also much less sensitive to water hardness chemicals, which cause scale formation, as a result of its low chemical reactivity. This low reactivity also makes antifreeze/coolant made with METALGUARD A80 much less sensitive to contaminants such as motor oil and other coolants.

Antifreeze made with METALGUARD A80 will be suitable for passenger cars, vans, SUVs, light trucks, heavy-duty vehicles and many off-road applications such as stationary engine cooling systems. It will provide superior corrosion protection for all cooling system metals, including aluminum, steel, cast iron, copper, brass and solder alloys. Compliance with the many dissimilar antifreeze specifications in today’s market also make it important to know what your additive package does not contain. METALGUARD A80 allows you to meet most of these exclusion requirements.

It is recommended that METALGUARD A80 be blended with virgin ethylene/ propylene glycol or with high-quality reclaimed ethylene/propylene glycol from vacuum distillation units meeting ASTM E1177. Deionized water should be used to make pre-diluted coolants.
