METALGUARD® A40

METALGUARD A40 is an all-organic OAT (organic acid technology) inhibitor package. It contains no, borate, nitrate, nitrite, phosphate or silicate. METALGUARD A40 contains organic acids and azoles to provide complete metal protection and guard the cooling system against corrosion and cavitation-erosion. In addition, it contains additives to minimize hot surface scaling while also preventing heat transfer surface foul ing due to minor oil leak age. Antifreeze made with METALGUARD A40 can be mixed with most major brands of OAT, HOAT and conventional anti-freezes without precipitation problems.

METALGUARD A40, when blended correctly, produces an ti freeze that can meet the ASTM D3306 specification for light-duty coolants. Antifreeze/coolant made with METALGUARD A40 provides a service life of 5 years or 150,000 miles, and is suitable for use in foreign and domestic passenger cars, vans, SUVs and light trucks requiring extended life antifreeze.

This extended life additive system can be used with either virgin or high quality reclaimed glycol from distillation units. WEBA Technology recommends that you send a sample of any non-virgin glycols that you are considering for use with METALGUARD A40 to a laboratory for analysis in accordance with ASTM E1177, and send us the results. We will help you determine if the glycol is suitable for use, with or without pre-treatment.
