Description

ТO-29-2 is a two part low viscosity epoxy infusion resin developed for high temperature complex shape composite tooling. ТО-29-2 offers simple and flexible processing due to low viscosity at low impregnation temperature (25°С). Pre-curing at room temperature allows to remove composite tool from plastic model. Post-curing at 200°С provides service temperature of tool up to 220°. Self-heating time of 500g from 20°С to 60°С is more than 8 hours.
