Been using 2 part epoxy both 5 minute and 30 minute in small jobs.. Does the 30m cure time provide a stronger bond, or is it just the curing times.

Thanks

Longer the curing time stronger the bond I believe Ian

From actual tests that I have done, it doesn't matter which you use. These tests have been done several times over the years.

THE WOOD BREAKS EVERY TIME NOT THE GLUE.

There is another factor which relates to a property of the glue called toughness. Brittle at one end of the scale, tough at the other. A tough glue tends to deform a little, storing energy when stressed. A brittle glue does not move, and stress concentrates at a point, leading to local failure, and this is the initiator of total failure. You will find that long cure epoxies are tougher. The wood fails first with either, but a slow cured joint tends to fail at a higher stress level. ARTF users find that old hot melt joints fail. The reason is that the plasticisers used in the glue leach out with time, and the plastic changes from tough rubbery stuff to brittle glass. But best is, don't hit the ground hard.
