METALGUARD A65
Precharged Extended Life Additive Package "Global" Type Formulation for use with Ethylene Glycol

Product Description and Applications
METALGUARD A65 is a fully-formulated, precharged extended life additive package developed specifically to allow the antifreeze producer to meet specifications for the global extended life category of antifreezes. METALGUARD A65 is a hybrid and nitrited organic acid technology (HOAT/NOAT) additive system, containing both carboxylic acids (OAT technology) and azoles/inorganic salts (conventional technology). While OAT-only antifreezes have compatibility problems with conventional antifreeze formulations, HOAT formulations are compatible with OAT, HOAT, NOAT (nitrited organic acid technology) and conventional azole/inorganic salt type antifreeze/coolants.

METALGUARD A65, when blended with ASTM antifreeze grade ethylene glycol/water in accordance with WEBA Technology’s instructions, will produce an antifreeze concentrate which contains a minimum of 2400 ppm nitrite, or 1560 ppm total nitrites plus molybdates, with at least 600 ppm of each (product can be ordered with molybdate/nitrite blend as METALGUARD A65M). The antifreeze/coolant will also have a pH of 9.8-10.7 (see specifications below), a minimum reserve alkalinity of 6 ml and a maximum silicate content of 250 ppm. It is phosphate-free (<15 ppm) and amine/triethanolamine-free.

Antifreeze made with METALGUARD A65 will be suitable for passenger cars, vans, SUV’s, light trucks and heavy-duty vehicles. It will demonstrate outstanding aluminum corrosion control in addition to superior protection for copper, brass, solder, steel and cast iron. METALGUARD A65’s substantial nitrite content will also control pitting/cavitaion damage to diesel engine wet sleeve cylinder liners. In heavy-duty applications, antifreeze made with METALGUARD A65 will have a service life of 600,000 miles with the addition of an additive booster at 300,000 miles. At every oil change the antifreeze should be checked to be sure that the pH is in the proper range and that the sample is free of significant precipitates, suspended solids, cloudiness or contamination.

Antifreeze blenders must demonstrate compliance with ASTM, Ford, Chrysler or other specifications with their antifreeze/coolant, because the quality of the glycol and water used is as important as the additive package. This extended life additive system can also be used with either virgin or high-quality reclaimed ethylene glycol from distillation units, reverse osmosis membranes, and most flocculation/filtration systems. WEBA Technology recommends that you send in sample of any non-virgin glycols that you are considering for use with any of WEBA Technology’s additive packages to a laboratory for testing, and send us the results. We will help you determine if any pretreatment will be necessary.

METALGUARD A65 is formulated to meet these Industry standards:

• ASTM D 3306
• ASTM D 4985
• ASTM D 6210
• TMC of ATA RP329/330/338

Nearly all of OEM automotive light-duty ad heavy-duty specifications are patterned after or identical to the ASTM standard specifications given above. For individual OEM specification compliance contact your sales representative. Note that the ASTM specifications listed include the key performance tests (ASTM D1384, D4340, D1881, D2570, D2809). See below for making specification claims.
