Toughening Agents for Adhesives and Sealants

B-Tough™ A3 by Cargill is a medium polarity, epoxy functional, reactive toughening agent. It provides impact strength to structural adhesives without impacting the hardness of the matrix.

• It protects substrates from moisture diffusion, extending the lifetime of the substrate.
• It is easy to formulate with and used in adhesives & sealants.
• It provides excellent stability and improved adhesion after humid aging.
• It enhances durability by absorbing microcracks caused by aging and thermal shock.
• Recommended dosage level of the elastomer phase is between 5 and 25%.
• B-Tough™ A3 is listed with FDA 21 CFR 175.105, FDA 21 CFR 175.300 and EU (No. 10/2011).
