ABRON – BR 729
ABRON BR 729 is a bismalimide based curator for epoxy resins to improve the thermal stability of the resultant cured resin. ABRON BR729 can be either dissloved in an solvent or added directly to the epoxy resin. No other catalyst is required to cure the epoxy resin. An addition of 20 wt % of ABRON BR729 in epoxy resin ( grade GY252 ) would give a increased Tg of 230oC and an addition of 30 wt % would give a Tg of 240oC.
