What is the WN Series?
[Anhydrous Liquid Additives]: Efficient, Stable, and Easy-to-Use – Engineered for Professional Coating Formulations
In today’s coatings market driven by environmental responsibility and high performance, the WN Series emerges as a tailor-made solution for formulators seeking flexibility, long-term stability, and outstanding compatibility. Developed by Chitec, the WN Series represents a line of liquid, anhydrous additives with high active content—providing a comprehensive and reliable solution for industrial, wood, and functional coatings.
【High-Stability Coating Additives】Five Key Technical Advantages of the WN Series
- Anhydrous High Concentration: Active ingredient content reaches 67–94%, significantly reducing required dosage.
- Liquid Format: Ready-to-use without dispersion, minimizing process issues.
- Superior Stability: Highly resistant to sedimentation and degradation, ideal for global supply chains and long-term storage.
- High Compatibility: Freely miscible with other stabilizers, minimizing incompatibility and delivering synergistic effects.
- Low Volatility & Low Emulsifier Content (for selected products): Suitable for applications requiring anti-fogging and stain resistance; effectively reduces foaming risk.
