QuangFeng UFL-400 is a specialized silicone water repellent and softening agent produced by the Environmental textile Auxiliary Agent Factory. As a block silicone oil, its unique molecular structure forms a durable hydrophobic barrier on fiber surfaces, causing water to bead and roll off without compromising the fabric's natural breathability. It is particularly effective for finishing polyester and nylon, where it penetrates deep into the fibers to reduce surface friction, resulting in a luxurious "soft and smooth" hand-feel. This transparent liquid formulation is solvent-based, ensuring high stability and compatibility for industrial textile processing.

• Appearance: Transparent liquid

• Composition: Silicon-Containing

• Purity: 38%

• Density at 20°C：0.8g/L

• Ionicity: Solvent-based

• Package: 120kg, 200kg

• Durable Water Repellency: Creates a strong hydrophobic layer that repels water and prevents moisture penetration in outdoor and high-performance textiles.

• Superior Softness and Smoothness: Reduces inter-fiber friction to provide a luxurious, silky touch often required for premium garments.

• High Stability (Block Silicone): The block copolymer structure offers better wash durability and stability compared to traditional amino-silicone oils.

• Enhanced Fabric Flexibility: Improves the elasticity and recovery of synthetic fibers, making them less prone to wrinkling and easier to care for.

• Transparent Formulation: The clear, solvent-based liquid ensures no discoloration, maintaining the original aesthetic of light-colored or white fabrics. 

• Performance Outerwear: Used for treating jackets, raincoats, and ski wear to provide essential waterproofing and wind resistance.

• Plush Toys and Fluffy Yarns: Applied to yarns and soft toys to maintain their fluffiness while adding a smooth, tactile quality that enhances consumer appeal.

• Synthetic Fabric Finishing: Ideal for polyester and nylon garments where a balance of water protection and a soft "hand" is needed.

• Outdoor Gear: Extends the service life of tents, backpacks, and sleeping bags by protecting against environmental moisture and UV degradation.

• Industrial Textiles: Used in technical fabrics that require mechanical durability combined with oil and water resistance.
