Fluorosilicone oil has many advantages as a surface treatment agent, which mainly come from its unique chemical structure and physical properties. The following is a specific analysis of the advantages of fluorosilicone oil as a surface treatment agent:

1. Excellent oil resistance, solvent resistance and chemical stability
Fluorosilicone oil introduces trifluoropropyl groups on silicon atoms, which makes it have excellent oil resistance, solvent resistance and chemical stability. These characteristics enable fluorosilicone oil to remain stable in various harsh chemical environments and is not easily corroded or decomposed.

2. Good hydrophobicity and oleophobicity
Fluorosilicone oil can form a molecular assembly film with an outer chemical composition of -CF3 on the surface of the substrate through chemical adsorption. This film has high hydrophobicity and oleophobicity, which can greatly reduce the friction coefficient of the substrate and make it have good wear resistance under low load. This feature makes fluorosilicone oil particularly suitable for surface treatment that requires waterproofing, anti-fouling and oil resistance.

3. Wide applicability
Fluorosilicone oil can be used for waterproofing and anti-fouling finishing of various materials such as fabrics, leather, paper, etc., and has oil repellency and solvent repellency. For fabrics, alkyl chains containing 8-10 perfluorinated carbon atoms can achieve the greatest waterproof and oil-repellent effect. In addition, fluorosilicone oil can also be used for waterproof and oil-repellent treatment of metal, glass, ceramic and other surfaces, as well as release agents for plastics and rubber and drag-reducing treatment agents for water and oil pipelines.

4. Environmentally friendly and non-toxic
As an environmentally friendly and non-toxic surface treatment agent, fluorosilicone oil will not pollute the environment or harm human health during use. This makes it more advantageous in the treatment of products that come into direct contact with the human body, such as textiles and leather products.

5. Long-term effect
The waterproof and oil-repellent layer formed by fluorosilicone oil has long-term effect and can maintain the waterproof and oil-repellent properties of the material for a long time. For example, when used in antifouling coatings for marine ships, its performance is better than that of silicone self-polishing coatings, providing a new way to develop non-toxic antifouling coatings for ship bottoms.

6. Diversified product forms
Fluorosilicone oil can be modified according to different application requirements to form products in different forms. For example, it can be prepared into emulsion-type, solvent-free or solvent-type products to adapt to different construction methods and substrate requirements.

In summary, fluorosilicone oil as a surface treatment agent has significant advantages such as oil resistance, solvent resistance, chemical stability, water and oil repellency, wide applicability, environmental protection and non-toxicity, long-term effect and diversified product forms. These advantages make fluorosilicone oil have broad application prospects in many fields such as textiles, leather, paper, metal, glass, ceramics, etc.
