STM-990 Coolant For Glass Grinding, Violet (55 Gallon Drum)

Item #STM990-D

SALEM'S new generation of STM coolants are formulated for centrifuge and soft settling system requirements and for systems requiring flocculation or coagulation. In addition to cooling, our new coolants also lubricate, inhibit rust and bacterial growth, control foam, settle debris and clean particulate form the work surface and coolant tanks.
STM990 is a high-quality synthetic coolant designed to work specifically with flocculant dosing systems - like the SALEM Clean 20. The formulation effectively manages the glass swarf by readily combining with an injected flocculant to eliminate diamond wheel glazing, clogged coolant lines and ensure thorough yet soft settling. The advanced lubricity of STM990 yields optimal grinding performance in the most demanding production applications by promoting high stock removal rates and producing excellent surface finishes. This comprehensively formulated coolant also exhibits low foaming as well as a biocide to minimize odor created by bacterial growth and is stable throughout a broad range of water conditions (hard to soft). Coolant concentration of STM990 should be checked daily.
