General-purpose silicone fluid. Dow XIAMETER PMX-200 Silicone Fluid, 500 CS Clear is a non-toxic, odorless polydimethylsiloxane polymer used for lubricating, electrical insulating, and furniture, metal, and automotive applications. Its medium 500 cSt viscosity strikes a practical balance between flow and body, making it a versatile choice for lubrication and insulating tasks as well as care and polish formulations.
Material and chemistry. PMX-200 is a polydimethylsiloxane polymer manufactured to yield essentially linear polymers across a range of viscosities, and it belongs to the long-established Dow silicone fluid family historically sold as Dow Corning 200 Fluid. This lineage gives it consistent, well-characterized behavior and the inherent water repellency typical of PDMS chemistry.
Functional properties. This 500 cSt grade offers high shearability, compressibility, and spreadability, together with low reactivity, low surface energy, and low fire and environmental hazards. The blend of easy spreading and low reactivity makes it well suited to forming thin, stable films for lubrication, release, and insulating duties without aggressive chemical behavior.
Durability and protection. The fluid is resistant to weather, water, chemicals, and oxidation, which supports its role as a durable lubricant and insulating fluid. Its resistance to environmental attack helps treated surfaces and components maintain performance over time, whether the fluid is used as a lubricant, a release agent, or a dielectric medium.

Available Variants
PMX200 500CS 5GL — 5 gallon kit
PMX200 500CS-GL — 1 gallon jug
Both variants are the identical 500 cSt PMX-200 fluid repackaged by KitPackers, sharing the same chemistry and properties; they differ only in fill size. The 1-gallon jug suits smaller or intermittent use, while the 5-gallon kit suits higher-volume lubrication, insulating, or formulation work.

FAQs
What is the 500 cSt PMX-200 fluid typically used for?
It is a medium-viscosity, general-purpose silicone fluid used for lubrication, electrical insulation, and release duties, and as an active ingredient in furniture, metal, and automotive care formulations. Its balance of flow and body allows it to spread into thin, stable films while still delivering meaningful lubricating and insulating performance.
Is the 500 cSt fluid safe and low-odor?
The source describes this grade as non-toxic and odorless, with low reactivity and low fire and environmental hazards, making it suitable for many indoor and industrial settings. As with any chemical, the product and Safety Data Sheets should be reviewed before use, storage, and disposal to ensure safe handling.
How resistant is it to the environment?
This grade is described as resistant to weather, water, chemicals, and oxidation, and like other PDMS fluids, it is inherently water-repellent. That resistance helps treated components and surfaces withstand moisture, temperature fluctuations, and chemical exposure, supporting reliable long-term performance in lubrication, insulation, and surface-treatment roles.
What is PMX-200 chemically, and how does viscosity affect it?
PMX-200 is a polydimethylsiloxane (PDMS) polymer offered in many viscosity grades from thin to very thick. At 500 cSt, it is a medium grade: thicker than lubricating oils yet still readily spreadable. Lower grades flow more freely, while higher grades give more body and gloss depth.
What is the difference between the 1 gal jug and 5 gal kit?
Both packages contain the same 500 cSt fluid with identical chemistry and properties; only the fill size differs. Choose the 1-gallon jug for smaller, intermittent, or lower-throughput use, and the 5-gallon kit for higher-volume lubrication, insulating, or formulation work where larger quantities are consumed regularly.
