I. Material Properties and Addressing Industry Pain Points

Fluorosilicone oil, as a fluorine-modified silicone material, has a fluorine-carbon (C-F) bond energy of up to 485 kJ/mol in its molecular structure, endowing the material with exceptional chemical stability. In leather treatment, the following are demonstrated:
Penetration Advantage: Fluorosilicone oils with a viscosity range of 50-500 cSt (25°C) can penetrate the microporous layer (pore size 0.1-10μm) of the leather fiber network, achieving a 40% penetration depth compared to traditional silicone oils.

Revolutionary Handfeel: By reducing the surface tension to 16-18 mN/m (water is 72 mN/m), the dynamic coefficient of friction of leather is reduced to 0.15-0.25, achieving a touch similar to baby skin.

Durability Test: After 5,000 Martindale rubs per ISO 5407, the water repellency retained over 85% of its initial value.

II. Key Technical Nodes of Process Innovation
Modern tanneries primarily use a three-stage process for applying fluorosilicone oil:

Pretreatment (acidic environment, pH 3.5-4.0) → Impregnation (50-60°C constant temperature bath) → Heat setting (120°C x 3 min)

Key Control Parameters:
Positive correlation curve between penetration time and temperature (R²=0.92)
Emulsion particle size must be controlled below 100nm (DLS measurement)
Additional dosage is typically 1.2-1.8% of the leather weight.
