Are All 2 Pack Epoxy Glues Created Equal?

I am looking to repair a bronze statuette with 2 pack epoxy glue. In looking at the Bunnings and Mitre 10 websites there are quite a number to choose from. The reviews are a bit confusing as to the pros and cons of each brand. Some say the cheap "Utility" brand $2.65 one from Bunnings will do the job as all 2 pack epoxy glues are chemically the same (which I don't believe). Others say go for a brand $10 more expensive. One thing I have gleaned is that a 24 hour one is far stronger than a 5 minute or 90 second fast setting ones.

Can anybody recommend the strongest 2 pack epoxy glue(s)?

    no. Some are quick. Some are slow. Slower curing ones tend to be stronger.
    Don't get resin on your hands or you'll get allergic.

    Do you need the strongest?

    Sort by rating, check a product is suitable, sanity check a few reviews and go from there.

    Here's the top rated one. It mentions adhesion strength in excess of 2500 psi (up to 4000 psi):

    If strength is important many of them list adhesion strength in KG or psi.

    For those types of jobs I prefer Gorilla Clear Epoxy Glue

    Depends what form the repair requires. Does it need to resist gravity (hold it from falling)? If it sits there without any glue and it just to prevent it falling if knocked a lesser glue might do

    There are 2 part epoxy specific for metals. I cannot remember where I seen them.

    Hi

    I have been in the adhesive industry for best part of 20 years. Epoxy is exceptionally strong, one of the strongest commonly available adhesives, typically 10 - 40 MPa.. The key to any adhesive is ensuring the surfaces to be bonded are clean and free of contamination, and that the part A and B are fully mixed. For a small thing like you are doing it will make no relative difference as long as correctly cleaned, mixed and assembled before the pot life is expired, and then held in position so not to seperate while it sets. No not all epoxies are equal but for your need the differences are irrelevant
    The main thing people usually do wrong is mix in unequal parts, if that happens either insufficient catalyst is added, so the adhesive never fully cures to the right strength , or too much is added and it sets too rapidly. Add according to instructions and you will be right
