CYCOM 997 resin is a controlled flow; 350°F/177°C curing, toughened epoxy resin with 350°F/177°C dry and 250°F/121°C wet service capability.

CYCOM 997 is qualified to DMS 2224/2212. Typical applications for 997 include primary and secondary aircraft structures or any application where impact resistance and excellent hot/wet performance are crucial.

CYCOM 997 is formulated for ease of processing with excellent tack and drape which is retained for up to 20 days at RT in the prepreg form. A standard two hour cure at 350°F/177°C may be used in either an autoclave or press-mold. No post cure is required to achieve service temperatures. The recommended lay-up procedure for this material is L-3. The recommended cure procedure is C-5 or C-9.
