Cytec Industries Inc. (Woodland Park, N.J.) launched new products and accompanying technologies for serial automotive production. XMTR50 a new, two-part epoxy resin system, was developed specifically for the high-rate manufacture of components using a high-pressure resin transfer molding (HP-RTM) process, claiming a cycle time of three minutes at 120°C/250°F for a Tg of 135°C/275°F. MTM 23, the industry’s first application of a volatile-organic compound (VOC)-free thermoset vinyl hybrid resin, woven glass-reinforced prepreg, reportedly enables the manufacture of parts by press molding in five minutes or less. Cytec also introduced trademarked FM 3500 EZP peel ply, a resin-rich, fiber-free composite bonding product that reportedly eliminates the need for additional prebond surface preparation. Formulated specifically for one-piece removal, it exhibits handling properties that support manufacturing efficiency. The peel ply’s long shop life, durability during extended cure cycles and compatibility with most 177°C/350°F-cure prepregs allow for manufacturing flexibility.
