Product description

TC350-1 is a toughened epoxy prepreg with mechanical property translation and excellent hot/wet performance. TC350-1 is easily processed via out of autoclave or press curing operations.

TC350-1 develops a 191°C (376°F) Tg after a 177°C (350°F) cure, which coupled with low moisture absorption translates into excellent hot/wet performance.

TC350-1 is available in extensive fiber reinforcement formats: unidirectional tape, slit unidirectional tape, woven and non-woven prepregs.
