Castrol Brayco Micronic 889 is a clear and bright, synthesized hydrocarbon based, heat transfer fluid and dielectric coolant.

Brayco Micronic 889 is designed for use in electrical / electronic cooling of ground-based and airborne closed circuit systems. It offers high specific heat compared to other hydrocarbons, esters and silicone fluids. This product also provides superior oxidative stability, low temperature properties and hydrolytic stability characteristics unique to polyalphaolefin products. Brayco Micronic 889 has excellent dielectric properties and is harmless to most common construction metals. (Low acrylonitrile)
