Solvay HTM® 552 Bismaleimide Resin
Categories:	Polymer; Thermoset; Bismaleimide (BMI)
Material Notes:	Description: HTM552 is a bismaleimide resin matrix formulation that combines high temperature end-use performance with good hanleability during lay-up. HTM552 has been developed for use in structures whre critical load-bearing performance is required at temperatures greater than 200°C (392°F). In applications where components may be lightly loaded, intermittent periods at 250°C (482°F) can be sustained. HTM552 is also capable of enduring very short-term exposure to a temperature of 280°C (536°F). Features & Benefits: 30 day tack life at 21°C (70°F) 12 months storage at -18°C (0°F) Initial cure temperature of 190°C (374°F) Excellent tack and drape High flow system DMA E’ onset Tg of 282°C (540°F) Note 1: Material: HTM552-FT300B40B-199g/m2-2x2 twill; Cure: 6 hrs at 190° (374°F), 6.2 bar (90 psi) Note 2: Material: HTM552-AS4 (12K)-145g/m2-carbon fiber unitape; Cure: 6 hrs at 190° (374°F), 6.2 bar (90 psi); Post cure: 6 hrs at 240°C (464°F) Information provided by Cytec, subsequently acquired by Solvay.
