Recommended processing for RS-36 is described below. Special moisture control procedures and bleed bagging materials required for cyanate ester resin systems are not necessary for RS-36
CURE PARAMETERS:
- Apply vacuum and leak check. For autoclave or press cycles apply pressure of 45–85 psi
- Heat to 177°C (350°F) (5°C/+10°F) at 2°C (5°F) per minute ± 3°F/1.5°C per minute
- Hold at 177°C (350°F) for 90 minutes (+15 min/-0 min)
- For autoclave cures at 40–85 psig, vent to atmosphere at 20 psig or maintain dynamic vacuum, depending on structural Applications
- Cool at 5°F/min to below 60°C (140°F). Release vacuum and autoclave pressure
