Description

Resorcinol Diglycidyl Ether (CAS NO 101-90-6) is a high-purity, low-viscosity epoxy resin monomer that serves as a critical reactive diluent and cross-linking agent. Its unique chemical structure, featuring two glycidyl ether groups attached to a resorcinol core, provides enhanced reactivity and contributes to the thermal and mechanical properties of cured epoxy systems. This product is essential for formulators and manufacturers in the composites, adhesives, and electronics industries seeking to optimize resin viscosity, improve processing characteristics, and achieve superior final material performance.

Application

• Epoxy Resin Formulation: Primary use as a reactive diluent to reduce the viscosity of high-molecular-weight epoxy resins, improving workability and filler loading capacity without sacrificing cured properties.
• Advanced Composites: Key component in formulations for carbon fiber and fiberglass-reinforced composites used in aerospace, automotive, and wind energy applications, where high strength-to-weight ratios are critical.
• Structural Adhesives & Sealants: Used in high-performance adhesives for metal, ceramic, and composite bonding, offering excellent chemical resistance and bond strength.
• Electrical & Electronic Encapsulation: Employed in potting compounds, encapsulants, and insulating materials for semiconductors and electrical components due to its good dielectric properties and thermal stability.
• Coatings & Paints: Utilized in specialty industrial and protective coatings that require chemical resistance, durability, and fast curing cycles.
• Cross-linking Agent: Functions as a cross-linker in various polymer systems to enhance network density, thermal resistance, and mechanical rigidity.
