Castrol Brayco™ Micronic 889 is a clear and bright, synthesized hydrocarbon based, heat transfer fluid and dielectric coolant
Temperature Range Brayco Micronic 889 is designed to operate over the temperature range of -54ºC to 135ºC (-65ºF to 275ºF) Specification Brayco Micronic 889 is qualified to and meets the requirements of MIL-PRF-87252C. This fluid is identified by NATO Code Number S-1748.
Brayco Micronic 889 is designed for use in electrical/electronic cooling of ground based and airborne closed loop systems. It offers high specific heat in comparison to other hydrocarbons, esters and silicone fluids. This product also provides the superior oxidative stability, low temperature properties and the hydrolytic stability characteristics typical of polyalphaolefin products. Brayco Micronic 889 has excellent dielectric properties and is harmless to most common metals of construction. It is compatible with (low acrylonitrile) BUNA N compounds and fluoroelastomers such as Viton.
