C8 waterproof agent is an efficient waterproof and oil resistant finishing agent based on long-chain fluorocarbon compounds, widely used in fields such as textiles, outdoor equipment, and industrial protection. The following is a detailed introduction to its main features and applications:

1. Chemical composition and waterproof principle
The main components of C8 waterproofing agent are derivatives of perfluorooctane sulfonic acid (PFOS) or perfluorooctanoic acid (PFOA) containing 8 carbon atoms. The long carbon chains and fluorine atoms in its molecular structure endow extremely low surface energy (which can be reduced to 6mN/m), allowing water droplets to form a rolling effect on the fabric surface, achieving waterproof and oil resistant functions.

2. Performance advantages
Efficient Protection: Compared to C6 waterproofing agent, C8 has better waterproof and oil resistant performance, especially suitable for high oil pollution environments (such as industrial protective clothing) and extreme outdoor conditions (such as assault suits and tents).
Durability: It can withstand more than 50 washes and has good high-temperature stability, making it suitable for products that require long-term use.
Compatibility: Suitable for various fibers (polyester, cotton, blended) and processing techniques (dip rolling, spray coating).

3. Typical applications
Outdoor equipment: hiking gear, tents, and other scenes that require high waterproof performance.
Industrial protection: Oil proof work clothes for petrochemical, food processing, etc.
Automotive interior: Enhance the weather resistance and stain resistance of automotive fabrics.
