Two Component Epoxy Adhesive EP31 Offers Outstanding Flexural Strength Properties

Recently, I recommended this product for an aerospace application where the shear and flexural strength requirements were very high. In the prototype phase, the customer tried a heat curing epoxy, but, their new design involved much larger parts. Therefore, the use of an oven for heating the epoxy was not possible. EP31 not only met their strength requirements, but, it also eliminated the need for an oven since it is a room temperature curing system.
