[Modifier] Why Is Epoxy Strong but Brittle? — Why Tougheners Are Needed

💡 In this Article The difference between strength and toughness The relationship between crosslink density and brittleness How tougheners help dissipate stress and improve fracture resistance Why Are Tougheners Needed? One request comes up surprisingly often when developing an adhesive: "Can we keep the adhesion strength but make it less likely to crack?" At first … Continue reading [Modifier] Why Is Epoxy Strong but Brittle? — Why Tougheners Are Needed →
