Technetters, I'm looking at part of IPC-4101C. Slash sheet /29.

For resin system, it lists 'Primary: epoxy', 'Secondary1: cyanate ester', Secondary2:N/A'.

Looking through the body of 4101, I see 7.2 has a table for 'material composition keywords' with 'epoxy/cyanate ester/woven glass' associated with /29.

Is 4101 saying that /29 material has a resin system which contains BOTH epoxy AND cyanate ester in a single sheet of laminate or prepreg?

As always, I appreciate any guidance from you ladies and gentlemen.
