TC275-1 is a dual cure toughened epoxy prepreg designed to facilitate composite part construction with low pressure or vacuum pressure cures. The resin system features a 14 day tack life and 21 day outtime to allow the construction of thick or larger composite structure. TC275-1 may be cured at a lower temperature of 275°F/135°C or can be cured at 350°F/177°C for higher temperature service.
- Dual cure prepreg system
- Robust processing and low voids under vacuum cure pressure (out of autoclave)
- Excellent resistance to hot/wet exposure
- High toughness
