OAT-908 incorporates cutting-edge inhibitor technology to provide a reasonably priced long life
antifreeze. OAT-908 is a hybrid organic acid technology (HOAT) additive/inhibitor package
formulated with a proprietary stabilization system to improve the durability of its carboxylate
salt base and extend its range of compatibility with both conventional inorganic salts and OAT-
type antifreezes. Virgin antifreeze made with OAT-908 provides a service life up to 150,000 miles
or 3000 hours. OAT-908 contains no phosphates, borates, nitrates, or silicates. This extended life
add pak possesses multiple complex carboxylic acid derivatives along with nitrite to protect all
six standard metal alloys (brass, copper, steel, solder, cast iron and aluminum).
These low foaming carboxylates and other proprietary ingredients not only provide broad-range metal
protection but also 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 fouling due to minor oil
leakage. This additives system can be used effectively with either propylene or ethylene glycols.
OAT-908 can also be used with either virgin or high quality reclaimed glycol from distillation
units, reverse-osmosis membranes, or some flocculation/ filtration systems. Additives Plus
recommends that all non-virgin glycol be analyzed to ensure glycol quality.
