High-Performance IOTA 25O Hydroxy Fluorosilicone Oil: A Versatile Material with Oil and Weather Resistance

Hits: 202 img

IOTA 25O hydroxy fluorosilicone oil is a hydroxy-terminated fluorosilicone polymer with trifluoropropyl side chains, which can also be a copolymer of fluorosilicone and silicone. This unique molecular structure endows the material with excellent oil resistance, solvent resistance, outstanding weatherability, and anti-aging properties, ensuring stable performance even in harsh environments. The introduction of trifluoropropyl groups significantly enhances the material's chemical inertness, enabling it to withstand corrosion from various chemical media such as fuels, lubricants, and organic solvents, while also exhibiting exceptional high- and low-temperature resistance, making it suitable for a wide temperature range from -60°C to 200°C.

The hydroxy-terminated design grants IOTA 25O hydroxy fluorosilicone oil high reactivity, allowing it to react with other functional groups to create new materials or crosslink into elastomers. This characteristic provides remarkable flexibility in material modification and composite applications. Low-viscosity IOTA 25O hydroxy fluorosilicone oil serves as an excellent structuring control agent for fluorosilicone rubber, effectively regulating processing and mechanical properties. Additionally, it can be used as a structuring control agent for conventional silicone rubber, partially introducing fluorosilicone characteristics to significantly improve oil and solvent resistance, thereby achieving performance upgrades at a lower cost with excellent cost-effectiveness.

Medium- to high-viscosity IOTA 25O hydroxy fluorosilicone oil is widely used in condensation-cured room-temperature vulcanized (RTV) silicone rubber applications, functioning both as a base polymer and a diluent to adjust system viscosity. In the production of oil-resistant sealants and mold-making rubbers, it serves as a key raw material, imparting superior resistance to fuels and lubricants to the final products. This makes it suitable for demanding sealing applications in automotive engines, aviation fuel systems, and other harsh environments. Furthermore, the material plays an important role in electronic potting and industrial anti-corrosion coatings, where its stable chemical properties and excellent adhesion make it the preferred choice for high-end sealing and protective materials.

The low surface tension and excellent leveling properties of IOTA 25O hydroxy fluorosilicone oil also make it highly effective in coatings and surface treatment applications, enabling the formation of uniform, dense protective layers that effectively block moisture, oil, and other corrosive media. In industries such as aerospace, automotive manufacturing, and petrochemicals, this material is widely used for long-term protection of critical components. With advancements in industrial technology and increasing environmental requirements, the demand for high-performance fluorosilicone materials continues to grow. Thanks to its versatility and reliability, IOTA 25O hydroxy fluorosilicone oil is becoming a core material choice for an expanding range of high-end applications.
