TECHNICAL DATA SHEET
CYCOM® 6826 Phenolic Resin
DESCRIPTION
CYCOM® 6826 is a self‐extinguishing, self‐adhesive, low smoke, low‐heat‐release phenolic resin. It can be processed by
vacuum bag, press or autoclave methods. CYCOM 6826 is offered two product forms: a tacky, drapable prepreg for the
fabrication of complex vacuum bag or autoclave cure parts and a low‐tack prepreg for press cured parts.
