In the process of continuous upgrading of synthetic resins such as polyurethane, polyester and epoxy resin towards high-performance and functionalization, how to precisely introduce the unique properties of organosilicon through chemical bonds into the main chain of the resin, rather than just through physical blending, has become the core technical path for material modification. The product carbon hydroxyl-modified silicone oil 28830, as a modified silicone oil with aliphatic carbon hydroxyl groups, demonstrates significant application value in the synthesis of organosilicon modified polyurethane copolymers and the modification of various resins, providing a precise and efficient reactive modification scheme for the development of high-performance resin materials.


I. Core Structural Characteristics and Physical Properties of the Product


Product carbon hydroxyl-modified silicone oil 28830 is a colorless to slightly yellow, transparent to slightly turbid liquid with a functional group of two, a molecular weight of three thousand, a viscosity of seventy millipascal-seconds at 25 degrees Celsius, and a refractive index of 1.41. This product is a modified silicone oil with aliphatic carbon hydroxyl groups, without excess unreacted polyethers, with high purity, and can react with isocyanates to form high-quality organosilicon/polyurethane copolymers. The design of a molecular weight of three thousand provides an appropriate chain segment length, which can effectively exert the hydrophobic and flexible characteristics of organosilicon and maintain good compatibility with various resin systems.


II. Core Reaction Characteristics and Performance Advantages


The application value of product carbon hydroxyl silicone oil 28830 stems from the reactive aliphatic carbon hydroxyl groups in its molecular structure. These hydroxyl groups can react with isocyanate groups, embedding the polysiloxane chain segments chemically into the polyurethane main chain or side chain during polyurethane synthesis, generating organosilicon modified polyurethane copolymers. The modification method through chemical bonding does not have the common migration and precipitation problems of physical blending, and the modification effect is stable and long-lasting.


In terms of performance, this product can provide multi-dimensional performance improvements for modified resins: significantly enhancing the flexibility and tear resistance of the synthesized resins, allowing the materials to maintain structural integrity under repeated bending conditions; endowing the resins with excellent lubricity and wear and scratch resistance, improving the surface durability of the products; its organic silicon chain segments give the material good hydrophobicity and self-cleaning properties, making the coating surface less prone to staining; and improving the breathability and compatibility of the resins, expanding the application space of the materials in functional coatings.


III. Main Application Areas


Product carbon hydroxyl silicone oil 28830 can play an important role in the following key application areas, specifically:


1. Synthesis of organosilicon modified polyurethane resins and emulsions. The product can react with isocyanates to synthesize organosilicon modified polyurethane copolymers, suitable for polyurethane coatings, adhesives, and elastomers. The modified polyurethane maintains the original mechanical properties while significantly improving surface hydrophobicity, stain resistance, and hand feel.


2. Copolymerization modification of polyester and acrylic resins. The product can participate in the copolymerization reaction of polyester and acrylic resins, introducing organic silicon chain segments into the resin main chain, giving the resin good hand feel, smoothness, and improving wear resistance and anti-sticking performance.


3. Two-component polyurethane varnish and amino varnish. The product added to the two-component polyurethane or amino varnish system can significantly improve the smoothness, anti-sticking, and surface hydrophobicity of the coating, while also giving the coating excellent hand feel and self-cleaning properties.


4. Resin modification agents with high softness requirements. This product is suitable for use as a resin modification agent with high softness requirements, enhancing the flexibility, tear resistance, lubricity, breathability, compatibility, wear resistance, and hydrophobicity of the synthesized resins, suitable for high-end paints, leather coating, and other fields.

Product carbon hydroxyl silicone oil 28830 is available in 20-liter and 200-liter iron drums, and can be provided in other specifications upon customer request. After being sealed, the product is stored in a dry and cool place, avoiding contact with acids and alkalis, and keeping away from fire sources. Under the condition of meeting the storage requirements and without being opened, the effective storage period is twenty-four months.


V. Quality Assurance and Application Value


During the production process, the product carbon hydroxyl silicone oil 28830 has established a strict quality control system. Key indicators such as product appearance, functionality, molecular weight, and viscosity are inspected throughout the process to ensure consistency and reliability between batches. As the demand for high-performance modified resin materials in industries such as polyurethane, coatings, and adhesives continues to grow, this product, with its precise bivalent functional group reaction structure, the long-lasting modification effect brought by chemical bonding, and stable quality performance, is becoming an important reactive modifier option in the organic silicone modified resin field. It provides strong raw material support for promoting product innovation and technological upgrading in the downstream industries.
