Thermoset Tow prepreg and matrix resin, BARRIZOW (Developed products)
BARRIZOW is a gas barrier thermosetting epoxy resin for CFRP layers of high-pressure vessels.
Its high gas barrier properties are expected to reduce the amount of gas leakage from the vessels and enable a thinner barrier layer and liner-less tank.
There are various grades with different viscosity and shelf life suited to tank molding methods.
Features
- Excellent Gas Barrier Properties
- Good impregnation, moldability for carbon fiber and excellent mechanical properties
- Available for Filament Winding (FW) molding, Resin Transfer Molding (RTM) molding or coating
- For hydrogen, oxygen, nitrogen and argon, etc.
