Primary Chemistry:
Polyalphaolefin (PAO)
Royco® 602 is a synthetic PAO-based coolant engineered for use in avionics and other sensitive electronic applications. Royco® 602 fluid is specifically engineered with robust hydrolytic stability and dielectric performance required in a wide range of modern technologies.
Royco® 602 oil does not react in the presence of water, leading to a much cleaner operating system and extending the lifespan of critical components.
Ineffective performance of aircraft component coolant fluid
Rapid rust or corrosion formation in critical aircraft system equipment
Poor oil stability or resistance to water washout
Royco® 602 meets MIL-SPEC performance requirements under MIL-PRF-87525 and NATO S-1748.
