Epoxy Resin T20-60



T20-60 is a two-part low viscosity epoxy infusion resin developed for mass CFRP production. The resin offers simple and flexible processing due to low viscosity and room temperature impregnation. T20-60 was developed specially for vacuum infusion molding, to produce laminates with low porosity and optimal mechanical performance.
