Ricon® 131

Ricon® 131 by Cray Valley (TotalEnergies) is a maleinized polybutadiene. Its varying carbon chain lengths between functional groups provide for varying sealant and hardness. In Ricon® 131, functional groups are added that can react with epoxy, amines, and hydroxyls. Has high performance and a liquid nature, which allows easy mixing. Its polybutadiene backbone improves the moisture resistance of the final product. The anhydride functional groups allow for adhesion improvement as well as compatibilization of polar and non-polar materials. It can be used in place of or in addition to anhydrides typically used in anhydride-based epoxy systems, and also in applications like low-temperature tackifier and non-extractable process aid.
