DP460 Epoxy Glue 50ml with Plunger

I have bought this a few months ago but only had a need to use it, expensive glue, which got to leak the white part of of it on the plunger side right away creating loads of mess and would not come out the way it should, very disappointed :(

WARM GLASS REPLY- I'm sorry to hear that your glue leaked. A member of our Customer Services Team will be in touch to resolve this with you

I did have some problems before in using this epoxy in bonding the metallic bail to the fusion glass cabochon.



Main problem arise from the fact that I used acetone, not only for initial cleaning and de-greasing the metallic bail and the glass cabochon (which is good) but as well, in cleaning the excess of the epoxy adhesive near the bail etc. So, using the acetone after you used the epoxy, it will affect the resistance of the epoxy overall. So, if you want to remove the excess of the epoxy, wait for 60 min, to have the initial bonding (still not completely cured) and use some q-tips dipped in isopropyl alcohol to remove the excess adhesive on and around the bail and if you stained somehow the glass cabochon. This alcohol will remove the excess semi-cured adhesive w/o weakening the adhesive structure under the bail as acetone might do.



So, as steps into bonding you better do this:



1. The glass area to be bonded to the bail, must be roughened with a diamond abrasive bit mounted in a rotary Dremmel or jewelry rotary tool. After you scratch the surface under the bail, you will roughen, as well the surface of the metallic bail.



2. Clean both the glass and the bail with a kitchen paper towel dipped in acetone or isopropyl alcohol, until the glass is screeching clean



3. Put the mixed epoxy, both on the bail and glass as well, with a clean toothpick, then use an office clamp to press the bail on the glass or other method



4. Put it away and do not touch for an hour



5. Remove the clamp and then clean with a q-tip dipped in isopropyl alcohol the excess of the adhesive on and around the bail



6. Put back the clamp and keep it so, for 24 hours



7. Now if still places with some hardened epoxy, clan it with the cutter and then with some acetone, but take care to not touch the bail, or under bail.

I bought a tube in August 2017 and used it then with success after having problems with the cheaper epoxys. For about a year I have not had any need to use it but now (Nov 2018) I have tried it and found it has failed to set hard even after 24 hours. It has been well (even obsessively) mixed as per instructions and both glass and bails have been acetone cleaned (although that should have no effect upon its setting). Disappointed as it is not a cheap product and should not deteriorate over 15months.



Warm Glass response -

DP460 has an official shelf life of 15 months in original containers at room temperature and a shelf life of 2 years in their unopened containers. Epoxy will usually work fine well beyond the official shelf life.



If the epoxy does not harden, the mix may have been too lean on the hardener, mixing a teaspoon full usually fixes this issue.

I tried many other glues before DP460 and this is the only glue I have complete trust in now. It is more expensive than some other types but I have used the same tube for many hundreds of bails - all reliably stuck fast! Definitely well worth the peace of mind, knowing that customers are not going to come back to me with problems.

This is the only glue I've used on my glass pendants and I know they're safe. It goes a long way. Seems expensive at first, but I've already used my first one for hundreds of pendants and there's plenty left too.
