B-Tough™ A3

Our epoxy functional toughening technology brings impact strength to structural resins and adhesives without impacting the hardness of the matrix. It enhances durability by absorbing microcracks caused by ageing and thermal shock. B-Tough A3 is a reactive toughening ingredient that brings excellent stability and is recommended for use in liquid and/or solid type epoxy resins (high polarity grade).
