VITECH Composites manufactures Towpregs of grades 3K, 6K, 12K, 24K (Based on E, R, S glass fiber or cabon fiber 240 to 550 GPa modulus) using our own formulation of chemical B-stage epoxy called “RV405”, which was specifically designed for the Filament Winding process.

Our “RV405” range of Towpregs are curable within or out of autoclave in a range of temperature from 80 °C to 120 °C with a maximum dry Tg of 120 °C.

“RV405” Towpregs comply with REACH regulations.
