Description

TK123 is a two-part low viscosity epoxy infusion resin developed for tooling up to 120°С, or CFRP parts with sustainable properties up to 90°С. The resin offers simple and flexible processing due to low viscosity at room temperature (lower than 500 mPa·s at 25°C). TK123 was developed specially for vacuum infusion molding, to produce laminates with low porosity and good mechanical performance.
