Products Description
RDGE is a high-temperature resistant epoxy reactive diluent with a relatively low viscosity at room temperature. It features high reactivity, minimal Tg influence, and low curing shrinkage rate. The cured product exhibits excellent electrical properties and long-term heat resistance.
RDGE can not only reduce the viscosity of epoxy resin, but also maintain the initial mechanical properties and heat resistance of epoxy resin.
The activity of RDGE is ten times that of the commonly used bisphenol A type epoxy resin. When RDGE is added to the epoxy resin system, it can enhance the reaction activity of the system and accelerate the curing speed.

FAQ
Q: Why RDGE is suitable for aerospace prepreg formula?
A: It reduces epoxy viscosity for good fiber wet‑out. After curing, it retains high Tg, mechanical strength and thermal performance, unlike ordinary diluents which degrade final properties.
Q: What is the main risk during handling?
A: It irritates skin and mucous membranes. Wear gloves and goggles, avoid skin contact and inhalation of vapor.r.
Q: Do you supply samples?
A: Samples are available.
Q: Could you provide COA and MSDS?
A: Yes, batch‑wise documents can be offered.
Q: What solvents can RDGE dissolve in?
A: Insoluble in water. Miscible with acetone, methanol, chloroform, benzene, ketone‑type solvents and most epoxy resins.
