Master Fluid Solutions Introduces TRIM® MicroSol® 685XT, a High-lubricity, Low-foaming Semisynthetic Metalworking Fluid

TRIM MicroSol 685XT provides excellent cooling and mechanical lubricity, along with the machine friendly characteristics you expect from a premium TRIM coolant.


Perrysburg, Ohio, August 09, 2023 – Master Fluid Solutions is proud to announce our new, semisynthetic microemulsion coolant with a formula that offers the performance of a heavy-duty soluble oil with the cleanliness of a semisynthetic. TRIM® MicroSol® 685XT provides superior corrosion inhibition on all ferrous and nonferrous metals, performing well where traditional soluble oils may not cool sufficiently.


“TRIM MicroSol 685XT expands our industry-leading portfolio of metalworking fluids for the North American market and continues the legacy of MicroSol 685 while improving its foam profile for today’s demanding high-pressure, high-volume CNC machines,” says Justin Geach, Global Director of Marketing. “Offering excellent sump life, tool life, and surface finishes for a wide range of drilling, milling, turning, and tapping operations, the new TRIM MicroSol 685XT is a first-choice metalworking fluid for both production and multi-metal job shop environments.”


TRIM MicroSol 685XT is an excellent alternative to soluble oils on high-silica aluminum alloys and is compatible with a wide range of materials. With extreme hard water stability, TRIM MicroSol 685XT maintains superior sump life without the use of tank side additives and is free of nitrites, phenols, sulfurized EP additives, and triazine.
