The Magic of Fluorosilicone Oil

Hits: 811 img

Fluorosilicone oil has a trifluoropropyl group introduced onto the silicon atom, in addition to the basic characteristics of methyl silicone oil, it also has excellent resistance to oil, solvents, and chemical stability, and has good lubricity under extreme pressure conditions, which can be used as a lubricant, defoamer, surface treatment agent, release agent, and additive widely in the fields of cosmetics, petroleum, leather, paper, and pharmaceuticals. It can be used in open systems at temperatures ranging from -40 to 240°C. 


Used as a lubricant. 

Fluorosilicone oil can form an outer chemical layer with a chemical adsorption on the substrate surface with a chemical group of -CF3, which has a highly hydrophobic and hydrophobic molecular assembly film, which can greatly reduce the coefficient of friction of the substrate and make it have good wear resistance at low load. 

When used as a base oil for lubricating grease, trifluoropropyl silicone oil can significantly improve the lubricity between steel and steel interfaces. For the watchmaking and micro-mechanical industries, due to the surface energy of these compounds being as low as 20 mN/m, surface friction coefficient can be reduced, and they can also be used as high-end lubricants. Lubricants made from fluorosilicone oil, perfluoropolyether, and polyphenylene oxide are used for lubrication of record drive mechanisms, laser printers, and other electronic machinery, which can withstand temperatures above 121°C and operate at a high speed of 1.4 million revolutions per minute without decomposition, and provide reliable performance to the lubricated components. 

Typical applications: 

1. Vacuum pump lubricating oil for handling chemical reaction gases; 

2. It can be used for lubricating bearings in extremely low and extremely high temperature environments. 

3. Chemically inert to fuels and other chemicals, used in steam power cycle systems; 

4. Base oils used to thicken lubricating greases; 

5. Lubricating oil base oil for the watch and micro-mechanical industries. 


It is used as a surface treatment agent for fabrics, leather, paper, etc. 

Fluorosilicone oil is often used for waterproofing and dirt-repellent finishing of fabrics, leather, etc. and has oil-repellent and solvent-repellent properties. Generally, an alkyl chain with 8-10 full fluorocarbon atoms is needed to achieve the maximum waterproof and oil-repellent effect. For fluorinated organosilicon polymers with the same number of carbon atoms, the straight-chain ones have more effective waterproof and oil-repellent properties than the branched ones. 

1. Fluorosilicone oils containing the 7-fluoroisopropyl (or ethyl) side chain have a unique T-shaped fluorinated structure that gives the product excellent fluorine shielding effects. Used in fabric finishing, it can greatly improve the water-repellent, oil-repellent, and stain-resistant properties of fabrics. 

2. Fluorosilicone oil made from thiol silicone oil and fluorinated monomers (such as fluoroacrylate) can improve the oil-repellent properties of textiles, especially fiber products, after application. 

3. The fluorosilicone oil obtained by reacting allylsiloxane with fluorosulfonic acid in the presence of AIBN at 100℃-105℃ is used for finishing cotton fabrics, and the finished fabrics still have good water-repellent and oil-repellent properties after dry cleaning and wet cleaning. 

4. Synthesize a fluorosilicone-modified polyurethane waterproof and oil-repellent finishing agent using perfluorinated alkenes, hydroxy silicone oil, ethylene oxide, and diisocyanates. It is used for waterproof and oil-repellent finishing of textiles and leather, etc., which can provide excellent waterproof and oil-repellent properties, as well as increased softness, smoothness, and elasticity. 

5. Fluorosilicone oil is obtained by polymerizing hydrogen-containing polysiloxane and fluorinated olefins under a catalyst, and the fluorine content in the polymer can be controlled. It can be widely used as a waterproof and oil-repellent treatment for textiles, paper, metals, glass, ceramics, and plastics and rubber as a demoulding agent and a lubricant for water and oil pipelines. 

6. Glass wool impregnated with fluorosilicone oil has excellent waterproof, oilproof, and corrosion-resistant properties, which are used in chlor-alkali industry desuperheaters. The desuperheating efficiency is significantly improved, reducing equipment corrosion and significantly extending the service life of the desuperheater, while improving the quality of liquid chlorine and hydrogen chloride. 

7. Solvent-based products made with fluorosilicone oil containing alkene groups as the base polymer can be used as release agents and have good adhesion to various substrates (paper, plastic film). 

8. Mix fluorosilicone oil, aminosilicone oil, epoxy silicone oil, polyether silicone oil, cationic/nonionic mixed surfactants, and deionized water at a temperature of 56°C-60°C for 3-5 hours to form an oil agent used in the carbon fiber drawing production process. The oil agent forms a uniform film on the surface of each filament, preventing filament adhesion and twinning, and also preventing friction and wear between the fiber surface and rollers during production. It has excellent lubricity, anti-static properties, bundle properties, and self-emulsification properties. 


Used as a paint additive. 

Fluorosilicone oil paint has the properties of high temperature resistance, hydrophobicity, oil repellency, resistance to solvents, weather resistance, etc. When used in anti-fouling coatings for marine ships, its performance is superior to that of self-polishing coatings made of silicone-based materials, providing a new approach for developing non-toxic bottom anti-fouling coatings. When used in protective coatings for solar energy devices in desert areas, it can take advantage of its low surface energy and self-cleaning properties. Due to its low friction coefficient during film formation, it can be used as lubricating and protective coatings for magnetic recording media and some optical instruments and equipment, such as camera lenses. 

A water-based coating made of fluorosilicone oil containing end hydroxyl groups, small molecular siloxane, nanometer-sized silica dioxide, decabromodiphenyl ether, etc. has excellent flame retardancy, resistance to solvents, oil, high and low temperatures, and good self-cleaning properties. The surface of the coating is smoother, and it can form a film in one step, which can be used for a long time and has a service life of more than 20 years. By copolymerizing (methyl) acrylic fluoroester, alkoxy organosilicon containing alkene, and alkenyl monomers, the resulting product is a fluorosilicone copolymer water-based coating that has excellent adhesion to various substrates and a coating film with excellent resistance to acid, alkali, and durability. 


Used as a defoamer. 

Because the surface tension of fluorocarbon-based silicone oils, especially long-chain perfluorinated alkyl silicone oils, is lower than that of other silicone oils, the defoamers made from them are more effective at lowering the surface tension of various foaming systems than other silicone oil defoamers. Both homopolymeric and copolymeric fluorocarbon-based silicone oils can be used as defoamers. Fluorosilicone oil defoamers can be used in the petroleum, textile, synthetic rubber, and resin industries, as well as in the paint and ink, food processing, and fermentation industries, and in medical applications. 


Application of Fluorosilicone Secondary Products 

Fluorosilicone grease, Fluorosilicone paste 

Fluoroalkyl silicone oil can be used as a base oil, and by adding thickeners, stabilizers, and modified additives, it can be used to prepare fluorosilicone grease and fluorosilicone paste. When trifluoropropyl silicone oil is used as the base oil for lubricating grease, it can significantly improve the boundary lubricity between steel and steel. It can be used alone or mixed with dimethyl silicone oil or methylphenyl silicone oil, and its lubricity is significantly better than that of chlorinated phenylsilicone oil, and even better than mineral oil-based lubricating grease at high loads. The thickener can be divided into lithium soap-based (fluorosilicone grease) or white carbon black and silicone resin (fluorosilicone paste) based on the product form. The coarse product obtained by mixing the base oil, thickener, and modified additive is then further ground in a three-roll mill to obtain a uniform product without coarse particles of thickener or modified additive, such as fluorosilicone grease or fluorosilicone paste. 

Fluorosilicone grease is suitable for temperatures ranging from -70 to 252°C and can be used for lubrication and sealing of high-speed, heavily loaded bearings in contact with chemicals, as well as lubrication and sealing of valves in contact with corrosive compounds. Fluorosilicone grease can also be used as a high-vacuum silicone grease and as a lubricant and sealant for parts in contact with benzene-based solvents. 

Fluorosilicone Release Agent 

Fluorosilicone oil can also be used to prepare release agents, which have good anti-adhesion and lubricating properties, do not corrode molds, are non-toxic and safe, and can be used in molding, pouring, encapsulation, and coating processes. Fluorosilicone oil-based polymer formulations can be used to prepare emulsion or solvent-free products, which can be used as paper separators with very unique properties.
