METALGUARD® A80-PSi

METALGUARD A80-PSi is a nitrite-free OAT additive package that contains phosphate and silicate, but does not contain amine, borate, nitrate, nitrite or 2-ethylhexanoic acid. METALGUARD A80-PSi 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.

METALGUARD A80-PSi provides multiple levels of corrosion protection for cooling system metals. Silicate provides rapid aluminum protection and phosphate provides rapid protection for a broad range of metals. The organic acid salts in A80-PSi provide enduring protection for all metals over an extended service life.

A major advantage of this type of additive system is that it provides total cooling system protection for up to 600,000 on-road miles without the use of additive-containing coolant filters or supplemental coolant additives (SCA’s). The addition of a METALGUARD A80-PSi 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. This inspection should be in addition to the parameters that are normally checked in a routine or scheduled maintenance program.
