TRIM MicroSol 590XT Semisynthetic Microemulsion

Master Fluid Solutions reports that TRIM MicroSol 590XT, a semisynthetic microemulsion, in addition to being qualified for areas 5 and 6 of the Boeing process spec BAC5008, is now also qualified for use in area 2. The approval for Boeing usage area 2 includes machining heat-treated steels as described in BAC5008 and BAC5440. Boeing usage area 5 approval includes machining of non-sealant and non-paint parts not described in BAC5008 specification areas 1 through 4, while area 6 includes machining, grinding, or cutting detail parts and assemblies made of titanium alloys. MicroSol 590XT approval can be found in Boeing document PSD 6-137.

Heat-treated steels, titanium, and titanium alloys are commonly used in the aerospace industry, including Boeing and their subcontractors. These approvals allow Boeing and their subcontractors to use MicroSol 590XT to machine these high-tech aerospace alloys to make parts for all space and aircraft including the 737, 767, 777, and 787 families of airplanes.

“MicroSol 590XT not only meets the demands of specific aerospace customers, but it is also environmentally and regulatory compliant for the foreseeable future. The expanding Boeing area approvals allows Boeing and its subcontractors to utilize MicroSol 590XT in many more manufacturing operations.” stated Master Fluid Solutions’ director of global aerospace strategic business unit, Monte Dhatt.

MicroSol 590XT improves on the performance of previous generations with a stability package using environmentally safe ingredients. MicroSol 590XT is free of chlorine, triazine, formaldehyde releasers, phenols, boron, DCHA and secondary amines. It dramatically extends useful life without the need for tank-side biocides or fungicides, according to the company. MicroSol 590XT provides corrosion inhibition on all ferrous and nonferrous metals and keeps parts and machines clean to reduce maintenance and production time.
