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.

Room temperature curing Master Bond EP31 epoxy adhesive is designed for high performance structural bonding. It has a lap shear strength of 4,600 psi and a peel strength of > 40 pli. It also features a flexural strength of 13,200 psi. EP31 is resistant to exposure to many chemicals, including oils and fuels. The cured adhesive is a superb electrical insulator. Shrinkage upon cure is extremely low.
Master Bond EP31 has a 100 to 30 max ratio by weight. Working life for a 100 gram mass after mixing is > 30 minutes. It has a Shore D hardness of > 75. Its service operating temperature range is -60°F to +250°F. EP31 contains no solvents or volatiles. Adhesion to metals, ceramics, glass, rubbers and most plastics is excellent. It is easy to apply. A non-drip version called EP31ND is also available for use.
