Technical Data Sheet: Antmee® Fluoro Silicone Fluids Series

Product Name: Antmee® Fluoro Silicone Fluid
Chemical Description: Trifluoropropylmethylsiloxane-Dimethylsiloxane Copolymer / Fluorosilicone Oil
CAS Number: 63148-56-1 
Molecular Structure: Linear polysiloxane with trifluoropropyl (-CH₂CH₂CF₃) functional groups

1. Product Overview

Antmee® Fluoro Silicone Fluids are a series of high-performance, fluorinated linear polysiloxane fluids engineered to deliver superior chemical resistance and lubrication under the most demanding service conditions. By incorporating trifluoropropyl functional groups into the siloxane backbone, these fluids combine the inherent thermal stability and low surface tension of conventional silicone oils with the exceptional resistance to fuels, solvents, and aggressive chemicals characteristic of fluorocarbons .

Unlike standard polydimethylsiloxane (PDMS) fluids, which swell or degrade upon prolonged exposure to hydrocarbon oils and solvents, Antmee® Fluoro Silicone Fluids maintain their physical integrity and lubricating film strength even when immersed in gasoline, jet fuel, chlorinated solvents, and aromatic hydrocarbons. This makes them the lubricant of choice for aerospace fuel system components, automotive seals, chemical processing equipment, and any application where incidental or continuous contact with aggressive fluids is unavoidable .

The series spans a comprehensive viscosity range from 50 cSt to 13,000 cSt, allowing formulators to select the optimal grade for applications ranging from low-viscosity precision lubrication to high-viscosity damping and sealing.

Disclaimer: Typical values are representative of average production lots and should not be interpreted as guaranteed batch-specific specifications. Minor variations are expected due to normal manufacturing tolerances.

3. Standard Specifications by Viscosity Grade

Please refer to the specific Antmee® product code for detailed Certificate of Analysis (CoA) data, including precise viscosity, density, and fluorine content.

Antmee® FLS-50 (Viscosity: 50 cSt)
A low-viscosity fluorosilicone fluid offering excellent penetration and wetting characteristics. Antmee® FLS-50 is ideally suited for precision lubrication of close-tolerance mechanical components, as a carrier fluid for specialty greases, and as a surface treatment agent where deep substrate penetration and minimal residue are required. Its low viscosity ensures rapid spreading and complete coverage of complex geometries .

Antmee® FLS-100 to FLS-300 (Viscosity Range: 100 cSt to 300 cSt)
These medium-low viscosity grades represent the workhorse range for general-purpose fluorosilicone applications. They provide an optimal balance between flowability and film-forming capability. Antmee® FLS-100 and FLS-300 are widely used as base oils for high-performance lubricating greases, defoaming agents in solvent-based coatings and oil processing, and release agents for aggressive molding environments .

Antmee® FLS-500 (Viscosity: 500 cSt)
A medium viscosity fluorosilicone fluid offering enhanced film strength and durability compared to lower viscosity grades. Antmee® FLS-500 is recommended for applications requiring a more robust lubricating film, including bearing lubrication in chemical pumps, seal lubrication in valve stems, and as a damping fluid in mechanical instruments exposed to harsh environments .

Antmee® FLS-1000 (Viscosity: 1,000 cSt)
A globally recognized industry standard for high-efficiency defoaming and durable lubrication. Antmee® FLS-1000 provides exceptional anti-foam performance in solvent-borne coatings, inks, and adhesives, often effective at addition levels as low as 1 ppm . It also serves as a premium base fluid for specialty greases and as a long-lasting lubricant for seals, O-rings, and elastomeric components in fuel and chemical handling systems.

Antmee® FLS-10000 (Viscosity: 10,000 cSt)
A high-viscosity fluorosilicone fluid offering superior film strength and extended service life under boundary lubrication conditions. Antmee® FLS-10000 is specifically engineered for applications requiring exceptional resistance to wash-off and mechanical shear, including heavy-duty bearing lubrication, gear box lubrication in chemical plants, and as a viscoelastic damping medium in precision instruments.

Antmee® FLS-13000 (Viscosity: 13,000 cSt)
The highest viscosity grade in the Antmee® Fluoro Silicone Fluids series. Antmee® FLS-13000 provides maximum film thickness and durability, making it the fluid of choice for the most demanding sealing and damping applications. It is particularly effective as a lubricant for slow-moving, heavily loaded components and as a sealant barrier fluid in high-pressure chemical injection systems.

4. Primary Applications

• Chemical-Resistant Lubrication: Essential lubricant for bearings, gears, valves, seals, and O-rings operating in direct contact with fuels, solvents, acids, and aggressive chemicals. Prevents swelling, embrittlement, and premature failure of elastomeric seals .

• High-Performance Defoaming: Ultra-efficient anti-foam and defoaming agent for solvent-borne coatings, printing inks, adhesives, and oil-based processing fluids. Provides rapid foam knockdown and sustained foam control at exceptionally low use levels .

• Aerospace and Defense: Critical component in fuel system lubricants, hydraulic fluids, and specialty greases for aircraft, spacecraft, and military vehicles requiring reliable operation under extreme temperature cycling and chemical exposure .

• Mold Release Agents: Provides clean, multiple-release performance for rubber, plastic, and composite molding operations involving aggressive resin systems and high processing temperatures. Resists buildup on mold surfaces and does not interfere with post-mold finishing operations.

• Precision Instrument Damping: Serves as a viscoelastic damping fluid for optical instruments, measuring devices, and electromechanical actuators requiring stable, temperature-insensitive resistance to motion.

• Textile and Leather Treatment: Imparts durable water repellency, oil repellency, and anti-fouling properties to technical textiles, protective apparel, and high-performance leather goods .

5. Packaging and Storage Information

• Packaging Options: Available in 20 kg pails, 50 kg HDPE drums, or 200 kg steel drums depending on viscosity and volume requirements. Custom packaging available upon request.

• Shelf Life: 48 months (4 years) from the date of manufacture when stored in the original, unopened container under recommended conditions . Fluorosilicone fluids exhibit exceptional long-term stability and do not readily oxidize or polymerize during storage.

• Storage Conditions: Store in a cool, dry, and well-ventilated area away from direct sunlight and sources of heat or ignition. Keep containers tightly sealed when not in use to prevent contamination by dust or moisture. Recommended storage temperature range: 5°C to 35°C. Product is not sensitive to freezing cycles; however, viscosity will increase at sub-zero temperatures. Allow material to equilibrate to ambient conditions before use. Avoid contact with strong oxidizing agents.
