In March 2023, China’s “List of Key Controlled New Pollutants (2023)” took effect. PFOA (C8) and its related compounds are now banned in most industrial sectors. Only seven exemptions remain, including semiconductors, specialty protective textiles, and implantable medical devices. For textiles, paper, leather, and coatings, finding safe, compliant, and high‑performing alternatives has become a must.
Lianzhuang technology’s C6 fluorinated agents offer excellent water, oil, and stain repellency with good chemical stability. They meet most application needs. They are an ideal replacement for C8 agents. They help the industry move toward shorter‑chain, greener chemistry.
Core advantages of C6 agents
- Eco‑compliant– C6 agents degrade faster in the environment. They meet global environmental trends and China’s new pollutant control requirements.
- High performance– C6 agents give excellent water, oil, and stain repellency. They work on many fabrics and processes.
Recommended Lianzhuang C6 products
TEXNOLOGY®FCB058 washable water and oil repellent
This multifunctional agent gives excellent water, oil, and stain repellency. It also resists washing and dry cleaning. Treated fabrics repel water and oil effectively – liquids bead up and roll off. Daily cleaning is easy with a tissue or towel. This greatly improves fabric maintainability and convenience.
TEXNOLOGY®LG62 three‑proof and stain‑release agent
Based on a special fluorinated chemical structure, this agent combines repellency with easy cleaning. Treated garments resist water, oil, and stains. Even if stains occur, you can wipe them off with a damp cloth or remove them through normal washing. The agent gives low yellowing and low color change. It hardly affects the original shade. Its wash durability is excellent – protective performance stays high after many washes.
TEXNOLOGY®560 low‑temperature crosslinking water repellent
This agent cures at just 110°C. It gives excellent water repellency and wicking resistance. Treated fabrics often score full marks in water repellency tests. It also has good wash durability. The low curing temperature suits mills that lack high‑temperature drying equipment above 140°C. It works well on shoe materials and webbing for anti‑wicking finishes. Treated fabrics stay soft. If you do not need special hand feel, you can skip additional softeners – this simplifies the process and controls costs.
TEXNOLOGY®FCB028 cost‑effective repellent for polyester
This product offers outstanding cost‑performance. For polyester fabrics, you only need about 1% add‑on. It gives excellent water repellency at low cost. It is an economical choice.
Important points when switching to C6
- Substrate and process fit– adjust formulas and parameters for different materials like textiles and non‑wovens.
- Performance verification– check penetration, uniformity, and durability to meet end‑use standards.
- Supply chain management– ask suppliers for environmental safety data sheets. Ensure traceability and testing to confirm no banned C8 substances.
- Clean production– even with lower‑risk C6 agents, minimize emissions and follow clean production principles.
With tightening regulations and the push for green upgrades, C6 agents are not just a compliance choice. They are a key technical path for sustainable industry growth. Lianzhuang technology will keep providing high‑performance, traceable, and eco‑friendly C6 solutions. We help textile mills transition smoothly and stay competitive.
