Product description

TC420 is a flow controlled cyanate ester prepreg, toughened to resist microcracking.

TC420 is specifically formulated for out of autoclave large structures for ultra high temperature conditions. It can act as a self-adhesive system, is easy to process and yields low void laminates with a flexible cure cycle under vacuum only pressure. TC420 is also autoclave processable.
