In industrial fields such as high-end manufacturing, new energy, construction, electronics and electrical engineering, the temperature resistance, weather resistance, insulation, water resistance, and toughening properties of materials are the keys to ensuring product reliability and service life. As a silicone intermediate with reactive functional groups, hydroxyl silicone oil, with its excellent compatibility and reactivity, has become a core modifier in resin modification, rubber processing, coating preparation, electronic potting and other fields, empowering the upgrading of traditional industrial materials and promoting the development of green, low-carbon, and high-performance new materials.
In the silicone rubber industry, hydroxyl silicone oil is an indispensable structure controller and processing additive. One of the core raw materials of room temperature vulcanized (RTV) silicone rubber is terminal hydroxyl silicone oil, which undergoes condensation reaction with cross-linking agents and catalysts at room temperature to rapidly cure into an elastomer without high-temperature heating, making it convenient for on-site potting, sealing, and bonding. Hydroxyl silicone oil can adjust the hardness, elongation, and resilience of silicone rubber, and improve its high and low temperature resistance, aging resistance, and electrical insulation properties. It is widely used in electronic component sealing, pipeline sealing, building waterproofing, medical supplies and other fields. In the production of high-temperature vulcanized silicone rubber, hydroxyl silicone oil can be used as a structuring control agent to prevent the structured hardening of the compound during storage, ensure stable processing performance, and improve the yield of finished products.
In the construction and coating field, hydroxyl silicone oil is a key component to improve the weather resistance, water resistance and hydrophobicity of coatings. Introducing hydroxyl silicone oil into coating systems such as acrylic acid, polyurethane, and epoxy resin can graft onto the resin molecular chain through chemical reactions, significantly reduce the surface tension of the coating, endow the coating with excellent hydrophobic, antifouling, and self-cleaning effects, and greatly improve the UV resistance, aging resistance, and scrub resistance of the coating, extending the service life of the coating. It is especially suitable for exterior wall coatings, waterproof coatings, and industrial anti-corrosion coatings. Hydroxyl silicone oil modified coatings form dense films without cracking or chalking, with stable performance under extreme weather conditions, contributing to building energy conservation and long-life operation and maintenance.
The electronics and electrical industry has stringent requirements for material insulation, heat resistance, and moisture resistance, where the advantages of hydroxyl silicone oil are fully reflected. Its low dielectric constant and high volume resistivity make it a high-quality raw material for electronic potting adhesives and insulating coatings, which can be used for potting and insulation protection of circuit boards, sensors, transformers, new energy battery components, effectively blocking moisture and dust, resisting high and low temperature shocks and electrical breakdown, and improving the stability and safety of electronic equipment. In the new energy field, hydroxyl silicone oil modified materials can be used for battery pack sealing and thermal insulation, enhancing the environmental adaptability and safety performance of battery systems.
In addition, hydroxyl silicone oil is widely used in industrial scenarios such as defoaming, mold release, and waterproofing treatment. In sewage treatment, papermaking, chemical fermentation and other industries, hydroxyl silicone oil defoamers have long-lasting foam inhibition, high efficiency, good chemical stability, and no side reactions with the system; in plastic, rubber, and metal die-casting molding, hydroxyl silicone oil mold release agents have good lubricity, smooth mold release, no mold pollution, and do not affect the subsequent printing and bonding of products.
With the advancement of the "dual carbon" goal and the development of high-end manufacturing, the requirements for green, high-performance, and long-life materials are constantly increasing. As a non-toxic, low-volatility, and degradable silicone material, hydroxyl silicone oil reduces material loss and replacement frequency, lowers energy consumption and carbon emissions through the modification and upgrading of traditional materials, becoming an important force driving the green transformation of industry and the high-quality development of the new material industry, with a continuous rise in market demand.
