In the process of continuously developing towards functionalization and high-performance in fields such as textile printing and dyeing, polymer materials, and building materials, epoxy-modified polysiloxane intermediates with both reactive properties and excellent organic silicon characteristics are becoming the core raw materials for the development of downstream products such as amino silicone oils, block silicone oils, resin crosslinking agents, and building material additives. Our company's product epoxy silicone oil 105, as an epoxy polysiloxane, demonstrates significant industrial application value in areas such as textile post-treatment, resin modification and crosslinking, and building material enhanced waterproofing, providing flexible reactive intermediate options for customers in various industries.


I. Product Series Specifications and Core Physical and Chemical Characteristics


Product epoxy silicone oil 105 is a colorless transparent to slightly yellow liquid with a viscosity of 50 to 10,000 millipascal-seconds at 25 degrees Celsius, a specific gravity of 1.05 to 1.10, a pH value of 6.5 to 6.8, and a refractive index (nD25) of 1.410 to 1.450. This product offers four epoxy value specifications: 0.1, 0.3, 0.6, and 0.9, allowing for precise selection based on different downstream application requirements. In terms of molecular structure design, this product provides four different configurations: the double-end type (105-1) is suitable for manufacturing amino silicone oils and resin crosslinking agents; the double-end polymer type (105-2) is suitable for manufacturing block silicone oils; the end-chain type (105-3) is suitable for resin crosslinking agents, building material additives, and waterproofing agents; and the single-end type (105-4) is used as a chemical raw material intermediate.


II. Core Reactivity Characteristics and Performance Value


The application value of product epoxy silicone oil 105 stems from the epoxy groups in its molecular structure. The epoxy group is a highly reactive functional group that can undergo ring-opening addition reactions with nucleophilic reagents such as amines, hydroxyl groups, and carboxyl groups under mild conditions, thereby introducing polysiloxane chain segments into the target molecular structure.


In the textile chemical field, this product reacts with organic amines to manufacture amino silicone oils, and with polyether amines to manufacture block silicone oils, which are used in the production of various smoothing agents and softeners. In the resin material field, when used as a crosslinking agent, the epoxy groups react with the active groups in the resin to adjust the strength, flexibility, and reactivity of the resin. In the building materials field, by reacting with the active groups on the substrate surface, it enhances the strength and durability of the substrate, while also providing the material with good film-forming properties and waterproof functions.


III. Wide Application Domains and Selection Reference


Product epoxy silicone oil 105, with its multi-specification design and flexible reaction adaptability, plays an important role in the following key application domains:


1. Production of post-treatment agents for textile printing and dyeing. 105-1 (double-end type) is suitable for manufacturing amino silicone oils, giving fabrics a soft and smooth feel; 105-2 (double-end polymer type) is suitable for manufacturing block silicone oils, used in the production of various smoothing agents and softeners, especially for multi-functional post-treatment of high-end textiles.


2. Resin crosslinking agents and modifiers. 105-1 (double-end type) and 105-3 (end-chain type) are both suitable as resin crosslinking agents, adjusting the strength, flexibility, and reactivity of the resin. Epoxy silicone oil reacts with amine resins, polyurethane resins, etc., to increase the internal cohesion strength and adhesion of the resin, widely used in adhesives, coatings, and composite materials.


3. Building material additives and waterproofing agents. 105-3 (end-chain type) is widely used in the construction field, enhancing the strength and durability of the substrate, with good film-forming properties and waterproof functions. In cement mortar, concrete, and stone protection, the product penetrates the substrate interior, forming a hydrophobic layer, effectively preventing water penetration and pollutant adhesion.


4. Chemical raw material intermediates. 105-4 (single-ended type) can be used as an intermediate raw material for chemical production, for the synthesis of various special organic silicon compounds and functional materials.


IV. Packaging Specifications and Storage and Transportation Conditions


The product epoxy silicone oil 105 is packaged in 200-kilogram spray-painted iron drums, 50-kilogram or 100-kilogram plastic drums. It should be stored in unopened containers at an environmental temperature of 0 to 45 degrees Celsius. The validity period is one year.


V. Quality Assurance and Industrial Chain Value


During the production process of product epoxy silicone oil 105, a strict quality control system has been established. Key indicators such as product appearance, viscosity, specific gravity, pH value, refractive index, and epoxy value are tested throughout the process to ensure consistency and reliability between batches. As industries such as textile printing and dyeing, polymer materials, and building materials continue to develop towards functionality and high performance, the demand for epoxy silicone oil intermediates with both reactive properties and adjustable structures is steadily increasing. This product, with its series design of four molecular configurations, precise selection space of four epoxy values, and wide industry adaptability, is becoming an important raw material option for customers in various fields in the synthesis of organic silicon functional materials, providing strong raw material support for promoting product innovation and quality upgrading in related industries.
