ThinPreg™ 150SC is a hot-melt prepreg using a 100% solids, monomer-free, urethane-modified, vinyl-hybrid resin with excellent initiated stability and rapid cure at elevated temperature. ThinPreg™ 150SC can be cured in 1 minute at 150°C (302°F). This is achieved with a good out-life of up to 6 months at 18-22°C (64-72°C). It offers excellent mechanical properties on a wide variety of fibers. ThinPreg™ 150SC has an enthalpy of circa 70J/g. It can be used to make thick parts with low risk of exotherm. When curing the resin is less thermally stressed resulting in high ILSS performance; ThinPreg™ 150SC has an inter laminate shear strength equivalent to high performance structural epoxy prepregs.
- Features
• Snap-cure characteristics for fast cycle times
• Does not require frozen or refrigerated storage
• Designed for use with ATL machines and press molding or autoclaving Suitable tack for most hand layup and automated tape placement processes
• Ideal for prepreg from 50gsm to 300gsm
• Available on a variety of fibers

Safety & Health
- Health and safety
ThinPreg™ 150SC contains resins which can cause allergic reaction. When uncured, ThinPreg™ 150SC should be handled with appropriate gloves. When cured, a composite laminate made of ThinPreg™ 150SC should be cut, drilled or machined in a room equipped with an exhaust ventilation and filtration system, by operators wearing protective clothing and masks. Refer to Material Safety Data Sheet for further information.
