ABSTRACT:
The invention provides a thermosettable resin composition comprising (a) one or more thermosettable resins, (b) one or more of curatives, hardeners, and optionally catalysts for the curing of the thermosettable resin in an amount sufficient for the cure of the thermosettable resin, and (c) an effective amount of at least one non-functional cyclophosphazene to render said resin composition, when cured, flame retardant. The non-functional cyclophosphazene contains aryloxy group substitution and does not covalently bond with the resin network. As a result, the non-functional cyclophosphazene does not negatively impact key performance properties such as modulus, thermal stability, dielectric behavior, fracture toughness, moisture uptake or adhesion.
