Reviews

This is a very good epoxy. Slow set-up time gives you plenty of time for alignment after the glue-up.

I used this product to bond a steel axle to a titanium gear leg of an experimental aircraft. It was recommended by a builder of a similar aircraft. The adhesive worked perfectly. Follow the directions to the letter and you will get excellent results.

I bonded wood faring to steel. This product gives plenty of time to work with what your doing and after it cures you have a very strong bond.

This was a tough situation. I had to glue aluminum to neoprene to the bottom of a stool. This works better than anything else I’ve tried

Easy mixing and excellent strength when cured. Used this epoxy to repair a plastic headset yoke and it worked very good.

I had serious reservations about an epoxy glue claiming be able to bond aluminum. I decided to try it and so far so good. I've tried to break a few test bonds and adhesive has beat my best attempts.. The only negative is measuring is difficult because the catalyst is very sticky. I would recommend this product.
