TC275-1E 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 21 day tack life and 28 day total out time to allow the construction of a thick or larger composite structure. TC275-1E may be cured at a lower temperature of 135°C (275°F) or can be cured at 177°C (350°F) for higher temperature service. TC275-1E represents a long out time version of Toray’s popular TC275-1 resin system.
