III >■ 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 301 is a 250°F (121°C) to 300°F (149°C) cure, toughened, controlled flow epoxy resin system that has been the industry standard for over 25 years. Versatile processing, excellent mechanical properties, and long out time make 301 suitable for a variety of applications, including large scale structures where layup requirements can take days or weeks. Benefits/features • Excellent mechanical properties • Moderate tack • Good toughness • Controlled flow • Flexible processing Variants • 301-1: Increased tack • 301-D: Decreased tack • 301-5: Snap cure (3 min. at 300°F, 10 min. at 275°F) • 301-T: Clearer aesthetics Application 301 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 301 is typically cured at 250°F - 300°F (121°C - 149°C) depending on part size and complexity. With extended cure times, larger scale structures can be cured as low as 195°F-220°F (90°C-104°C). Low, medium and high pressure molding techniques may be used for curing. 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). ©2016 Mitsubishi Chemical Carbon Fiber and Composites, Inc.
