TRIM® MicroSol® 590XT – Milling,

Perrysburg, Ohio, December 20, 2017 – Master Fluid Solutions™ is pleased to report that

TRIM® MicroSol® 590XT, an advanced-technology, aerospace, semisynthetic

microemulsion, now has full Boeing approval for usage areas 1 through 6 as described in

BAC5008 and BAC5440. Usage area 1 is used for parts or assemblies subsequently to be

applied with paint or sealant. Usage area 1 also includes areas where fluid may contact

cured sealant and/or paint. Usage area 2 includes machining heat-treated steels in

accordance with BAC5440. Usage area 3 is used for drilling, reaming, or machining

dissimilar metal stackups containing high strength (180 ksi) alloy steel. Usage area 4 is

used for machining airplane aluminum exterior surface assemblies without requiring

disassembly for cleaning after use. Boeing usage area 5 includes machining of nonsealant

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 6-141.

Sealants, paints, heat-treated steels, dissimilar metal stackups, exterior aluminum

surfaces, 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


“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 validated performance of previous generations with a

robust stability package using environmentally safe ingredients. The formula is a favorite

of production mangers, environmental advocates, and safety professionals. 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. MicroSol 590XT provides superior corrosion inhibition on all ferrous

and nonferrous metals and keeps parts and machines very clean to reduce maintenance

and production time.

MicroSol 590XT is low foaming for today’s demanding high-pressure, high-volume

applications and it provides an optimized combination of cooling and lubricity to titanium,

aluminum, steel, stainless steel, and Inconel® machining applications.
