Typical applications Sporting goods Marine Medical Industrial manufacturing Out life 30 days at 70°F (21°C) Shelf life 6 months at 40°F (4°C) 12 months at 0°F (-18°C) Description 304-1 is a 250°F (121°C) to 300°F (149°C) cure, highly toughened, controlled flow epoxy resin system. Versatile processing, excellent mechanical properties, and long out time make 304-1 suitable for a variety of applications where strength and toughness are required. Benefits/features • High toughness • High impact resistance • Controlled flow • Moderate tack Application 304-1 can be supplied with most commercially available fibers (carbon, quartz, aramid, S-glass, E-glass, etc.) in both woven form (designated as NB) as well as unidirectional tape (designated as NCT). Woven fabrics are available in standard commercial widths up to 60 inches (1.5 m). Unitape widths up to 39 inches (1 m) are available in standard fiber weights ranging from 70 - 300 gsm (0.014 - 0.060 psf). Recommended processing conditions 304-1 can be cured at temperatures from 250-300°F (121-149°C) depending on part size and complexity. Low, medium, and high pressure molding techniques may be used to cure 304-1. Recommended cure cycle is 50 psi (345kPa), 3°F (1.7°C)/min ramp to 275°F (135°C), hold for 60 minutes, cool to <140°F (60°C). ©2016 Mitsubishi Chemical Carbon Fiber and Composites, Inc.
