HT&K Water Repellent Finishing Agent Key Products Development Background of Fluorine-Free Water Repellent Finishing Agent: With increasingly stringent environmental requirements, the use of fluorine-free water repellents is growing, and customer demands for fluorine-free water repellents are also increasing. Some customers require fluorine-free water repellents to achieve plant oil resistance on fabrics. To meet customer needs, a fluorine-free plant oil repellent has been developed. Multi-functional new products can be tested and developed according to customer functional requirements. Product Introduction: Poil is composed of special high molecular polymers. It has good waterproof performance on most clean cotton fabrics and good anti-permeation effect on common stains and oils in life (soy sauce, vegetable oil, animal oil, etc.). Product Application: Suitable for most clean fabrics, especially nylon and cotton fabrics. Product Specifications: No. Item Appearance Solid Content Type 1 Poil White Liquid 21% Environmentally friendly three-proof product, waterproof, oil-proof, and stain-proof Product Characteristics: 1. White liquid, weak cationic. 2. Excellent anti-permeation effect on plant and animal oils. 3. Good stability and continuous use. 4. Has a good water-repellent effect and can enhance the functionality of cotton. 5. Does not contain APEP, PFOS, PEOA, and formaldehyde and other prohibited substances. 6. Good wash fastness.
