Supplied byCray Valley (TotalEnergies)- Last Updated on May 1, 2026

Ricon® 131MA5 by Cray Valley (TotalEnergies) is a polybutadiene functionalized with maleic anhydride. Its varying carbon chain length between functional groups provides for varying sealant and hardness. In Ricon® 131MA5 functional groups are added which can react with epoxy, amines and hydroxyls. Has low molecular weight and liquid nature which allows easy mixing. Its polybutadiene backbone improves the moisture resistance of the final product. The anhydride functional groups allows for adhesion improvement as well as compatibilization of polar and non-polar materials. Ricon® 131MA5 can be used in place of or in addition to anhydrides typically used in anhydride based epoxy systems.
