Epotec RD 103 Reactive Diluent

Description

What is Epotec RD 103 Reactive Diluent?

Epotec RD 103 Reactive Diluent is a low-viscosity aliphatic di-epoxide derived from 1,4-butanediol, specifically developed to reduce the viscosity of high-viscosity epoxy resin systems. It blends seamlessly with a wide range of standard epoxy resins, regardless of the mixing ratio, offering excellent formulation flexibility.

This reactive diluent is di-functional, meaning it contributes to enhanced mechanical strength and improved toughness in the final cured product. Additionally, its molecular structure helps maintain much of the chemical resistance typically associated with unmodified epoxy systems.

Compatible with a broad spectrum of curing agents, Epotec RD 103 enables formulators to design systems with superior processing characteristics while retaining essential performance properties.
