^11 I I M HIGH PERFORMANCE MATERIALS 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 301T is a 250°F (121°C) to 300°F (149°C) cure, toughened, controlled flow epoxy resin system, with versatile processing, excellent mechanical properties, and long out time. The 301T is a version of 301 designed to improve surface finish for applications with stringent cosmetic requirements. Benefits/features • Optimized cosmetics for bladder molding • Moderate tack • Good toughness • Excellent mechanical properties • >30 days out time at 70°F (21°C) • Available on a wide range of unidirectional fibers and fabrics Application 301T is suited for structural applications in sporting goods, marine, medical, and industrial manufacturing. 301T can be supplied with most commercially available fibers in both woven form (designated as NB) as well as unidirectional tape (designated as NCT), including: carbon, quartz, aramid, S-glass, E-glass, and other specialty fibers and fabrics. Woven fabrics are available in standard commercial widths up to 60 inches (1.5 M). Unitape widths up to 39 inches (1M) are available in standard fiber weights ranging from 90 to 300 gsm. Recommended processing conditions 301T can be cured at temperatures from 250°F (121°C) to 300°F (149°C), depending on part size and complexity. Low, medium, and high pressure molding techniques may be used to cure 301T resin. Recommended cure cycle is 50 psi (345 kPa), 3°F (1.7°C)/min. ramp to 275°F (135°C), hold for 60 minutes, cool to <140°F (60°C). ©2015 Mitsubishi Chemical Carbon Fiber and Composites, Inc.
