Engineered specifically for liquid cooling systems in advanced military aircraft, missile guidance assemblies, airborne radar, and high-density avionics, Radcolube 500M provides superior heat transfer capabilities combined with exceptional dielectric insulating properties. Formulated to be hydrolytically stable and chemically inert, this non-aqueous PAO coolant prevents electrical arcing and dielectric breakdown while protecting high-power transmitters, Active Electronically Scanned Array (AESA) radars, and electronic warfare (EW) suites across extreme environmental temperature swings (-54°C to 135°C+).\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications \u0026amp;
