In application fields such as synthetic fiber lubrication, fabric functional finishing, and synthetic leather coating quality improvement, functional additives with excellent lubrication performance, water solubility, and reactivity are becoming the focus of the industry. Our company's product, 23667 Bisendohydroxy Polyether Silicone Oil, as a bisendohydroxy end-capped polyether modified organic silicone copolymer, demonstrates significant application value in synthetic fiber comprehensive treatment, fabric coating additives, and polyurethane resin modification, providing high-performance and multi-functional additive solutions for the textile printing and dyeing and synthetic leather industries.


I. Core Physical and Chemical Properties of the Product


Product 23667 Bisendohydroxy Polyether Silicone Oil is a pale yellow to amber transparent liquid with a viscosity of 200 to 500 square millimeters per second at 25 degrees Celsius. The active ingredient content is 100%, the specific gravity is 0.04, and the recommended dosage is 0.5% to 10%. This product is a bisendohydroxy end-capped polyether modified silicone oil block copolymer. The molecular chain contains both hydrophilic polyether segments and hydrophobic organic silicon segments, with reactive hydroxyl groups at both ends. Compared to ordinary silicone oil, its compatibility with organic lubricants is significantly better than conventional products, and due to the water solubility of the polyether segments, it is easier to remove from the fiber surface than ordinary silicone oil, without affecting subsequent dyeing, printing, and other processing procedures, which is crucial for the textile printing and dyeing industry.


II. Core Performance Advantages


Product 23667 Bisendohydroxy Polyether Silicone Oil demonstrates the following core performance advantages through its unique block copolymer structure:


Excellent wetting and lubrication performance. As a wetting agent in the organic lubricant formulation, it can be used in the comprehensive treatment of synthetic fibers, significantly reducing the friction coefficient between fibers and processing equipment and reducing breakage rates.


Antistatic properties. The ethylene glycol groups in the polyether chain segment can give fiber products good antistatic properties, reducing the impact of static electricity on the textile processing process.


Good water solubility and easy cleaning. The product can dissolve in water, and compared to traditional silicone oil, it is easier to remove from the fiber surface than ordinary silicone oil, without affecting subsequent dyeing, printing, and other processing procedures, which is crucial for the textile printing and dyeing industry.


Reactivity modification ability. The reactive hydroxyl groups at both ends of the molecular chain can react with functional groups such as isocyanate groups in organic polymers (such as polyurethane, polyester, etc.) through chemical bonds, introducing the organic silicon chain segment into the polymer network to enhance the hydrolytic stability of the resin. Unlike silanol-type hydroxyl silicone oil, the hydroxyl groups in this product are indirectly connected to the silicon atom through an alkyl group, forming a more water-resistant silicon-carbon-oxygen bond structure, which has better stability and application effect in polyurethane modification.


III. Main Application Areas


Product 23667 Bisendohydroxy Polyether Silicone Oil, with its multi-functional performance combination, can play a key role in the following application areas:


1. Synthetic fiber oil and lubrication treatment. In the spinning, drawing, and stretching processing of synthetic fibers such as polyester and nylon, product 23667 Bisendohydroxy Polyether Silicone Oil can be used as a smooth agent and wetting agent in the oil formulation. Its excellent compatibility with organic lubricants enables it to be uniformly dispersed in the oil formulation, effectively reducing the friction coefficient between fibers and metal guide wires, and reducing the occurrence of broken fibers and fuzz. The good water solubility ensures the thorough removal of the oil formulation in the subsequent refining process, without affecting the dyeing and printing performance of the fibers.


2. Fabric coatings and coating additives. In the polyurethane coating and printing paste formulations of fabrics, product 23667 Bisendohydroxy Polyether Silicone Oil is used as an additive, which can give the coating anti-adhesion properties, preventing the coating fabric from sticking during storage and use. At the same time, the organic silicon chain segments can enhance the wear resistance and scratch resistance of the coating, improving the durability and hand feel of the fabric.


3. Copolymer modification of polyurethane resins. The product dihydroxy polyether silicone oil 23667 has active hydroxyl groups at both ends of its molecular chain. These hydroxyl groups can react with the isocyanate groups in the polyurethane prepolymer, and the polymeric silicone segments can be introduced into the main chain of the polyurethane molecule through chemical bonds. This block copolymerization method can effectively improve the hydrolytic stability, heat resistance, and low-temperature flexibility of polyurethane materials, and is suitable for the development of high-performance polyurethane resins, coatings, and elastomer materials.


Four. Quality improvement of synthetic leather coatings. In the coating formulations of PU and PVC synthetic leather, the product dihydroxy polyether silicone oil 23667 can improve the fluidity and leveling of the binder, giving the finished product a smooth and lubricated surface feel, while enhancing the wear resistance and scratch resistance of the coating, and improving the comprehensive quality and grade of synthetic leather products.


Four. Packaging specifications and storage conditions


The product dihydroxy polyether silicone oil 23667 is available in two packaging specifications: 200 kilograms plastic drums and 1000 kilograms plastic drums. The product should be stored in a cool, ventilated, and dry place, avoiding direct sunlight and high-temperature environments. If unopened and in compliance with storage conditions, the shelf life is six months. Expired products can be used again after retesting and meeting the standards. This product is transported as non-hazardous chemicals.


Five. Quality assurance and application value


The product dihydroxy polyether silicone oil 23667 has established a strict quality control system during the production process. Key indicators such as appearance, viscosity, active components, and specific gravity are tested throughout the process to ensure consistency and reliability between batches. Please carefully read the safety data sheet and the hazard information about health and body on the container labels before use, and follow relevant safety operation procedures.


As the textile printing and dyeing and synthetic leather industries continue to upgrade towards higher quality, functionalization, and green processing, the demand for multifunctional additives with excellent lubrication performance, easy cleaning properties, and reactivity is steadily increasing. The product dihydroxy polyether silicone oil 23667, with its block copolymer structure design, the reactive modification ability brought by the double hydroxyl groups, and good water solubility advantages, is becoming an important additive choice for synthetic fiber processing, fabric coating finishing, and polyurethane material modification, providing strong technical support for the product upgrade and process optimization of related industries.
