Epoxy Resin TO200



ТО200 is a two-part epoxy resin with unique characteristics, combining high heat resistance, strength and processability. The impregnation temperature is 20-25°C. Flexible curing mode in combination with post-curing allows achieving the required heat resistance at the minimum curing temperature. The resin can be used for manufacturing CFRP or GFRP with sustainable properties up to 120°C, or for composite tooling with service temperatures up to 180 ° C.
