Our company's product, water-soluble silicone oil 1291, as a special organic silicone surfactant modified by polyether, demonstrates significant application value in multiple fields such as fabric finishing, leather coating, water-based coatings and inks, and personal care products. It provides efficient multifunctional auxiliaries solutions for customers in various industries.


I. Core Physical and Chemical Properties of the Product


Product water-soluble silicone oil 1291 is a colorless to light yellow transparent liquid with a density of 0.030 at 25 degrees Celsius. Its viscosity ranges from 500 to 1,500 centistokes, with a refractive index of 1.448 to 1.458. The 1% aqueous solution has a cloud point of 42 degrees Celsius, is completely miscible with water, and has a surface tension of 23 millinewtons per meter, with an effective content of over 99%. This product is a polymer of hydrophilic organic substances and hydrophobic polydimethylsiloxane, possessing the low surface tension of organic silicon and the hydrophilic characteristics of polyether chain segments, demonstrating excellent surface activity and formulation compatibility. The low cloud point design enables it to fully exert its wetting and spreading effects at room temperature during dilution and processing, reducing energy consumption. The effective content above 99% ensures that the product maintains stable performance even at high dilution ratios, and its complete miscibility with water greatly simplifies the formulation process.


II. Core Performance Advantages


Product water-soluble silicone oil 1291 exhibits the following core performance advantages through its polyether-modified molecular structure in various application systems:


Low surface tension and excellent wetting properties. The product significantly reduces the surface tension of aqueous systems, improving the wetting and penetration capabilities of various substrates, effectively reducing pinholes and orange peel surface defects.


Hydrophilicity, softness and smoothness, and anti-static properties. The hydrophilic polyether chain segments give materials good hygroscopicity and anti-static properties, while the organic silicon chain segments provide a soft and smooth feel. Together, they give the treated materials a comfortable touch and good dimensional stability.


Good透气性和成膜性. The product can form a uniform breathable protective film on the substrate surface， without affecting the material's透气 performance， and gives a glossy and smooth feel.


III. Main Application Areas


Product water-soluble silicone oil 1291 can play a key role in the following application areas， specifically：


1. Fabric finishing agent. When used as a fabric finishing agent， the treated fabric has soft， smooth， comfortable feel， good stiffness， good dimensional stability， and excellent dry-wet combing properties. It is suitable for soft and hydrophilic finishing of cotton， polyester， nylon and blended fabrics， improving the anti-static properties of the fabric， and suitable for underwear， sportswear and home textile products.


2. Leather slipper agent and coating agent. It is the main component of leather slipper agents and coating agents in the leather processing industry， giving various leather surfaces a smooth， shiny， soft and comfortable feel. It is suitable for surface coating and hand finishing treatment of clothing leather， shoe leather， sofa leather and automotive interior leather.


3. Water-based coatings and ink additives. It is used in water-based coatings， acrylic adhesives and inks， improving the fluidity of the system， making the product surface flat and shiny， suitable for water-based wood coatings， water-based industrial coatings， water-based printing inks and water-based varnishes.


4. Cosmetics and personal care products. The product can form a uniform breathable protective film on the skin surface， giving a soft and smooth skin feel， suitable for skin care lotions， shampoo and hair care products and bath lotions in personal care product formulations.


IV. Usage Suggestions and Recommended Dosages The addition amount of product water-soluble silicone oil 1291 in water-based systems is 0.5% to 1.0%. When used for surface anti-adhesion, the addition amount is 2% to 4%. The exact dosage should be determined through experiments based on the actual formula and application requirements. The product is fully miscible with water and can be directly added to the aqueous phase. The operation is convenient.


V. Packaging Specifications and Storage Conditions


Product water-soluble silicone oil 1291 is packaged in 25-kilogram, 50-kilogram plastic drums or 200-kilogram iron drums. This product is non-hazardous. During storage and transportation, attention should be paid to moisture prevention and the prevention of the admixture of various impurities. Under sealed and room temperature conditions, the shelf life is two years.


VI. Quality Assurance and Industry Application Value
