Product Overview

IOTA 279, also known as Epoxy-Terminated Phenyl Trisiloxane or Epoxy Phenyl Silicone Oil, is a high-performance organosilicon compound that stands out in the field of material science. This transparent liquid, ranging in color from colorless to light yellow, not only boasts an appealing appearance but also demonstrates remarkable capabilities in enhancing material properties.

Key Features and Benefits

IOTA 279 serves as a vital component in epoxy resin formulations, significantly improving the flexibility and electrical insulation properties of the resin. Additionally, it acts as a reactive modifier for polyurethanes and polycarbonates, enhancing their cohesive energy and providing superior high and low-temperature performance. This multifunctional modifier plays a crucial role in elevating the overall performance of materials.

Technical Specifications and Composition

IOTA 279 has an epoxy equivalent weight ranging from 260 to 340 g/equ, a refractive index (at 25°C) of 1.474, and a viscosity between 15 and 30 cst. Its primary component is phenyl trisiloxane with glycidyl groups at both ends, and it is free from any solvents. This composition ensures the product's purity and stability, laying a solid foundation for various applications.

Diverse Applications

IOTA 279 finds extensive use in modifying epoxy resins, polyurethanes, and polycarbonates. It significantly enhances the mechanical and physical properties of finished products while reducing cohesive energy. The modified materials exhibit improved resistance to high and low-temperature shocks, water, and weathering, as well as enhanced electrical insulation and resistance to atomic oxygen. These advantages make IOTA 279 highly sought after in aerospace, electronics, automotive manufacturing, and other industries.

Usage Guidelines

When modifying epoxy resins, simply add IOTA 279 directly to the prepolymer and cure together. For polyurethane modification, it can be used in conjunction with amine chain extenders or reacted with isocyanate groups through acid ring-opening. In the case of polycarbonate modification, IOTA 279 can be directly incorporated into the copolymerization process or added during molding and processing, offering flexibility and convenience.
