High-viscosity performance. Dow XIAMETER PMX-200 Silicone Fluid, 30,000 CS Clear is a high-viscosity, thermally stable polydimethylsiloxane polymer used for foam control, electrical insulation, leather finishing, protective coating, and furniture, metal, and automotive applications. Its elevated viscosity gives it greater body than thin, low-viscosity grades, which supports gloss depth, film-forming, and damping performance in finishing and coating work.
Material and chemistry. PMX-200 is a polydimethylsiloxane polymer manufactured to yield essentially linear polymers across a wide range of average kinematic viscosities; this particular grade is 100% active with an INCI name of Dimethicone. As a member of the long-established Dow silicone fluid family, it delivers the consistent, well-characterized behavior expected of PDMS chemistry, including inherent water repellency and thermal stability.
Functional properties. The fluid offers high shearability, gloss intensity, compressibility, and damping action, combined with low vapor pressure, low surface energy, low reactivity, and a low pour point. Together, these properties make it effective both where a durable, glossy silicone film is wanted and where a stable, low-volatility fluid is needed for insulating or damping roles.
Durability and protection. Because silicone fluids of this type are inherently water-repellent, PMX-200 30,000 cSt is described as resistant to abrasion, water, bacteria, and fungi. That resistance supports its use in protective coatings and finishing applications where the treated surface must withstand moisture, wear, and biological growth over time.

Available Variants
PMX200 30,000CS 500ML — 500 mL bottle
PMX200 30,000CS 5GL — 5 gallon kit
Both variants are the identical 30,000 cSt PMX-200 fluid repackaged by KitPackers, sharing the same chemistry and properties; they differ only in fill size. The 500 mL bottle suits small-scale, lab, or trial use, while the 5-gallon kit suits higher-volume production and finishing operations.

FAQs
What makes the 30,000 cSt grade different from lower-viscosity PMX-200 fluids?
It is a high-viscosity, thermally stable grade with far more body than thin, low-viscosity fluids. That heavier consistency supports foam control, protective coatings, leather finishing, and damping, whereas a thicker silicone provides greater gloss depth, film formation, and cushioning than lower-viscosity grades, which are used mainly for lubrication.
What is PMX-200 chemically?
PMX-200 is a polydimethylsiloxane (PDMS) polymer, manufactured to give essentially linear polymers at a defined viscosity. It is the same well-established silicone chemistry historically sold as Dow Corning 200 Fluid. This grade is 100% active and carries the INCI name Dimethicone, reflecting its pure silicone composition.
How resistant is this fluid to moisture and wear?
Silicone fluids of this type are inherently water-repellent, and this grade is specifically described as resistant to abrasion, water, bacteria, and fungi. That combination supports protective and finishing applications in which the treated surface must withstand moisture exposure, mechanical wear, and biological growth over an extended service life.
What does 'Packaged by KitPackers' mean?
The bulk Dow XIAMETER PMX-200 fluid is repackaged into these convenient bottle and kit sizes by KitPackers. The fluid itself is the genuine Dow silicone product; KitPackers simply provides the smaller, ready-to-use container formats rather than changing the underlying material or its documented properties.
Which package size should I choose?
Both packages contain the same 30,000 cSt fluid, so the decision depends only on volume. Choose the 500 mL bottle for small-scale laboratory trials or occasional use, and the 5-gallon kit for higher-volume production, coating, or finishing operations where larger quantities are consumed regularly and reordering frequency matters.
