1. Introduction
Leather, as a traditional material, is widely used in fashion, furniture, automobiles and other fields. With the continuous advancement of science and technology, the leather and leather chemical industry have higher and higher requirements for material performance. Fluorinated silicone oil, as a high-performance chemical additive, plays an important role in the leather processing process due to its unique chemical and physical properties, and can significantly improve the quality and performance of leather.



2. Basic properties of fluorinated silicone oil
Fluorinated silicone oil is an organic silicon compound with fluorine atoms introduced into its molecular structure, which gives it many excellent properties. First, fluorinated silicone oil has extremely low surface tension, which allows it to form a uniform film on the surface of leather, thus giving the leather good waterproof, oil-proof and anti-fouling properties. Secondly, fluorinated silicone oil also has excellent high and low temperature resistance, weather resistance and chemical stability, and can maintain its performance in various harsh environments. In addition, fluorinated silicone oil also has good lubricity and softness, which can effectively reduce the friction coefficient of leather, making it softer and easier to process.

3. Application of fluorinated silicone oil in the leather chemical industry
(I) Softener
In the leather processing process, the use of softeners can make the leather softer and more comfortable, and improve its feel and durability. As a high-quality softener, fluorinated silicone oil can effectively reduce the friction coefficient between leather fibers, making the leather softer and more comfortable during wearing and use. At the same time, fluorinated silicone oil can also improve the elasticity and toughness of leather, making it less likely to break and wear during repeated bending and stretching.

(II) Water repellents
Leather is easily corroded by water and oil during use, resulting in degradation of its performance and damaged appearance. Fluorine-containing silicone oil has extremely low surface tension and can form a uniform water-repellent film on the surface of leather, effectively preventing the penetration of water and oil. This not only keeps the leather dry and clean, but also extends its service life. In addition, the water-repellent properties of fluorine-containing silicone oil can also improve the anti-fouling properties of leather, making it easier to clean and maintain in daily use.

(III) Hand feeling agent
The use of hand feeling agent can improve the feel and touch of leather, making it more in line with consumer needs. Fluorinated silicone oil, as a hand feeling agent, can give leather a unique sense of smoothness and fineness, making it more comfortable and pleasant to touch. At the same time, fluorinated silicone oil can also improve the softness and elasticity of leather, making it more fit the curve of the human body during wearing and use.

(IV) Defoaming agent
In the leather chemical production process, the generation of foam will affect production efficiency and product quality. Fluorinated silicone oil has excellent defoaming performance and can quickly eliminate the foam generated during the production process. Its low surface tension and high chemical stability enable it to play a role in various complex chemical environments, effectively improving production efficiency and product quality.

(V) Brighteners
The use of brighteners can make the leather surface brighter and more beautiful, and improve its market competitiveness. Fluorinated silicone oil, as a brightener, can form a uniform bright film on the leather surface, making it present a unique luster under light. At the same time, fluorinated silicone oil can also improve the wear resistance and scratch resistance of leather, making it less prone to scratches and wear in daily use.

4. Application advantages of fluorinated silicone oil
The application of fluorinated silicone oil in the leather and leather chemical industry has many advantages. First, its versatility enables it to meet various needs in the leather processing process and improve production efficiency and product quality. Secondly, the chemical stability and weather resistance of fluorinated silicone oil enable it to maintain its performance in various harsh environments and extend the service life of leather. In addition, the use of fluorinated silicone oil can also improve the environmental performance of leather and reduce pollution to the environment.
