High-Performance Fabric Protection with Silicone Innovation
Advanced Nanotechnology, Superior Durability, Seamless Comfort.
Our advanced silicone resin based water repellent coating offers invisible, durable protection for all kinds of fabrics- without changing the look or feel. Silicone’s intrinsic hydrophobicity, combined with advanced nanotechnology, forms an ultra-thin breathable film on the fabric surface. This coating prevents water absorption while allowing air and vapor to pass through – making it ideal for both comfort and performance.
Unique Features of Our Fabric Water Repellent Coating:
- Durable Water Repellency– Long-lasting performance that resists everyday spills and stains.
- Wash Resistance – Effective protection that lasts through up to 4 washing cycles.(Surfactant wash)
- Multi-Fabric Compatibility – Suitable for cotton, wool, polyester, polyester blends, suede, velvet etc.
Technical Highlights:
- Advanced Nanotechnology : Forms a protective nano-shield on fabric , breathable yet highly water-repellent.
- Superhydrophobic Effect: Repels water-based stains such as coffee, juice, and wine.
- Non-Sticky Surface Feel: No change in look, color, or softness of the fabric.
- Air-Dry Technology : Quick drying at room temperature, no heat required.
Useful for applications like:
- Sofa Upholstery
- Carpet Protection
- Shoes & Footwear
- Bedsheets
- Headboards & Cushions
- Dining & Lounge Chairs
Water repellency study on Polyester Fabric
Polyester fabric was treated with LK-E 71 Fluid and air-dried at room temperature.
We visually observe the water-repellent performance of LK-E 71 Fluid, The water repellent action of the treated fabric are last for the 6 months.
The water-repellent performance was visually observed and measured by water drop contact angle analysis on treated and untreated fabric, further to simulate real-life use, the treated fabric was washed once using a mild surfactant solution, rinsed with water, and air-dried before re-evaluation.
Key Observations:
- Visual inspection confirmed strong beading and roll-off of water droplets on the treated surface.
- The initial contact angle of 150.2° indicates excellent hydrophobicity.
- Even after one cycle of surfactant washing and drying, the contact angle remained high at 148.9°, confirming the product’s strong durability under light-use conditions.
- This performance supports reliable water repellency for 5-6 months in typical dry-use applications.
Observation Table:
| Sample | Contact Angle (°) | Water Repellency |
|---|---|---|
| Untreated Fabric | 35.9 | No repellency |
| Treated (Initial) | 150.2 | Excellent repellency |
| After surfactant Wash | 148.9 | Excellent repellency |
Conclusion:
LK-E 71 Fluid provides durable and visually effective water repellency on polyester fabric, with excellent retention even after mild washing. This makes it ideally suited for textile applications where long-lasting (5-6 months) water protection is needed without frequent laundering such as interior furnishings, sofa fabrics, decorative textiles, and protective fabric coverings.
