In numerous industrial and consumer goods sectors such as metal die-casting, rubber and plastic molding, textile and leather processing, and personal care, functional additives that offer efficient demolding, excellent lubrication, long-lasting wear resistance, and environmental friendliness are becoming crucial elements for enhancing production efficiency and product quality. Our company's product, long-chain alkyl siloxane emulsion 28027E, as a water-based organic siloxane emulsion with a long-chain alkyl aryl-modified polysiloxane as the active ingredient, demonstrates significant application value in areas such as metal lubrication, die-casting demolding, plastic modification, chemical fiber spinning, oil additives, and personal care, providing customers in various industries with high-performance, multi-purpose emulsion-based additive solutions.


I. Core Physical and Chemical Properties


The long-chain alkyl siloxane emulsion 28027E has a milky white appearance and a solid content of 50% plus or minus 2%. This product is composed of a long-chain alkyl aryl-modified polysiloxane as the active ingredient and is dispersed in water through advanced emulsification technology. Its molecular structure combines the excellent flexibility and weather resistance of the silicon-oxygen main chain, as well as the hydrophilic property, lubrication, and adhesion brought by the long-chain alkyl and aromatic groups, enabling it to form a uniform and long-lasting protective film on various substrate surfaces.


II. Core Performance Advantages


The long-chain alkyl siloxane emulsion 28027E exhibits the following core performance advantages due to its unique alkyl aryl co-modification structure in various application systems:


Excellent lubrication, wear resistance, and high-temperature low carbon deposition performance. The introduction of long-chain alkyl and aromatic groups significantly enhances the hydrophilicity and thermal stability of the siloxane oil, compared to ordinary dimethyl siloxane emulsions, offering stronger lubrication durability and high-temperature anti-carbon deposition ability, particularly suitable for high-temperature die-casting processes of aluminum, zinc, and magnesium alloys.


Efficient demolding and high organic compatibility. The product maintains excellent emulsion stability under dilution and shear conditions, providing excellent demolding effects and good compatibility with organic coatings, inks, adhesives, etc., without affecting the secondary processing of the molded products such as painting, printing, and bonding.


Hydrophobic modification and smooth conditioning performance. The product can impart a hydrophobic, smooth, and glossy effect to the treated substrate surface, excelling in textile finishing, leather coating, and personal care formulations.


III. Wide Application Areas


The long-chain alkyl siloxane emulsion 28027E, with its multi-functional performance combination, can play a key role in the following application areas:


1. Metal die-casting and industrial demolding. The product is an important component for preparing water-based metal die-casting demolding agents and lubricants, particularly suitable for hot forming processing of aluminum, zinc, and magnesium alloys. Its excellent high-temperature resistance and low carbon deposition properties can effectively protect molds, extend mold service life, and improve the surface finish of castings. The product is also suitable for anti-sticking demolding of rubber, plastic, and polyurethane products.


2. Rubber and chemical fiber processing additives. In plastic modification and chemical fiber spinning oil formulation, the product can be used as a lubricant and anti-static agent, improving the processing smoothness and surface smoothness of fibers and plastic products.


3. Textile and leather finishing. The product can be used as a softening agent, waterproofing agent, and anti-staining agent for textiles, enhancing the softness, glossiness, and wrinkle resistance of textiles, and improving waterproof and anti-staining performance. In leather product manufacturing, it can be used to soften leather, increase glossiness, and improve touch, providing long-lasting moisturizing effects.


4. Coatings, inks, and personal care. In coating and ink formulations, the product can be used as a gloss enhancer, improving gloss and leveling. In personal care products, it can be used as a lubricant and softening agent in skincare products, hair care products, etc., improving skin feel and combing performance.


IV. Packaging Specifications and Storage Conditions


Product Long-Chain Alkyl Silicon Oil Emulsion 28027E is packaged in a standard 180-kilogram plastic drum. Customized small drum and ton drum specifications can be provided according to customer requirements. The product should be sealed and stored in a dry, cool, and well-ventilated warehouse, away from open flames, high-temperature heat sources, and direct sunlight. It should be transported as an ordinary organic silicon liquid chemical product to prevent packaging damage and leakage. Under the condition of intact original packaging and sealing, the product has a validity period of twelve months.


V. Quality Assurance and Industry Application Value


During the production process of product long-chain alkyl silicon oil emulsion 28027E, a strict quality control system has been established. Key indicators such as product appearance and solid content are tested throughout the process to ensure consistency and reliability between batches. As the metal processing, rubber and plastic molding, and fine chemical industries continue to upgrade towards water-based, efficient, and environmentally friendly directions, the demand for high-performance emulsion additives that have both lubrication and demolding functions, as well as long-term wear resistance and organic compatibility, is steadily increasing. Product long-chain alkyl silicon oil emulsion 28027E, with its unique alkyl-aryl co-modified structure, 50% stable solid content, and wide application adaptability, is becoming an important solution for customers in multiple fields in the selection of demolding lubrication additives, providing strong support for enhancing the quality and optimizing the process of the downstream industries.
