PU Based Fluorine-Free Water Repellent Dispersion Textile Grade

Description

1. Product Overview

PU Based Fluorine-Free Water Repellent Dispersion (Textile Grade) is a high-performance polyurethane formulation designed to impart durable water repellency to a wide range of textile substrates without the use of fluorinated compounds. It is primarily used in advanced textile finishing for apparel, outdoor gear, technical fabrics, and industrial textiles requiring eco-compliant water resistance. The product delivers an optimal balance of hydrophobic performance, fabric softness retention, and long-term durability under repeated washing and environmental exposure.

Strategically, it aligns with the global shift toward PFAS-free and environmentally responsible textile chemistries, making it a critical solution for brands and manufacturers transitioning to sustainable production standards.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Modified polyurethane aqueous dispersion (fluorine-free system)

• Appearance: Milky white liquid dispersion
• Ionic Nature: Non-ionic / weakly anionic system
• pH Value: 6.0 – 8.0
• Viscosity: Medium viscosity, optimized for padding and spraying applications
• Dilution: Readily dilutable in water systems
• Application Compatibility: Suitable for padding, exhaustion, and spray finishing processes
• Packaging Options: 50 kg drum / 120 kg drum / 1000 kg IBC tote
• Shelf Life: 6–12 months under sealed, cool storage conditions (5–30°C)

3. Core Industrial Applications

This dispersion is widely used in high-performance textile finishing across multiple industrial segments:

• Apparel Industry: Outdoor jackets, sportswear, rainwear, and performance clothing
• Home Textiles: Waterproof upholstery, mattress covers, and protective fabrics
• Technical Textiles: Automotive interiors, protective workwear, and industrial fabrics
• Footwear & Accessories: Water-resistant linings and synthetic leather treatments

It provides durable water repellency while maintaining fabric breathability and softness, outperforming conventional wax-based or silicone-only systems in wash durability and hand feel retention. Its fluorine-free chemistry ensures compliance with evolving global environmental regulations while maintaining competitive hydrophobic performance.
