Thread: Will this epoxy work as glue?

Why not use PVA?

From the blurb, I'd say it probably would work, but haven't tried it. Looking at the volume, in the container, how does the price work out compared to Techniglue, or the comparable product from Adhesive Engineering. It looks comparable.

I have used Titebond 3 in quite a few outdoor applications recently with no problems, but read of some issues in the US. I now use Sika tech glue, which is a urethane, totally waterproof. Why mess around with a product that isn’t specifically made for joinery?

There are a number of epoxies in self dispensing tubes at Bunnings but haven’t seen that one. It sounds more of a filler than an adhesive to me
Why not just get a product that is made for the job along the lines of this
Norglass Staybond Epoxy Glue, $39.95 | Whitworths Marine

Pricepoint is the same and it will be much easier to work with and a better colour. Most of the epoxies in the gun form are pink or off white colour

You don’t want to go to all the effort of making furniture only to have a failure with a simple issue of wrong glue selection

I’ve used that stuff and it’s strong as but it goes off in the mixing nozzle and therefore you need several if you don’t use the whole tube, same setup as chemset epoxy for holding down bolts. It’s clean to work with though, no atmospheres blowing around as you mix them in. I buy 20 litre packs of this 500 Series Epoxy Resin ( only for use with Fast, Slow or Super Slow hardener ) | Trojan Fibreglass Online
and then add fume silica powder (atmospheres) to it to make it whatever viscosity I need. It works out way cheaper and it lasts for a few years on the shelf. The dunlop tubes are fine for small jobs but you need several nozzles.

Or don’t use the mixing nozzles and dispense onto a sheet and hand mix. As RB said it goes off in the nozzle fairly quickly if you don’t keep dispensing the contents.

there’s this stuff. I’ve used it in boatbuilding. Very good as an adhesive , similar consistency to Vaseline. You scoop out a couple of similar sized blobs of each, mix it and use. Good open time too.

Thanks guys for the info and for providing the other options.

I'll do a bit more research.

I was planning on using Titebond III, just a little concerned about longevity being exposed to the elements

The only self-dispensing eopxy that I have used is Araldite. It works well enough, but most other epoxies are better.

I have done a lot of epoxy work, and the only epoxies I use now are WEST System or the local fibreglass shop's generic copy thereof. And almost always with the slow hardener option. I don't need to be rushed. I dilute the first coat with acetone or MEK to aid penetration then use straight. When needed, I thicken it with colloidal silica or saw dust

Epoxies must be mixed until they clarify, so I am very sceptical of any "self mixing nozzle"; sounds like a mass market good average product at best. But that might be all you need!

PS: If you haven't used epoxy before, then heed the safety instructions. It is seriously nasty stuff and the effects are cumulative.

The self mixing nozzles work well for construction grade applications like the various Ramset epoxies. You can glue threaded rod into a slab and get cyclone-rated pull resistance. For joinery? Don’t know. I have used West System for about….thirty years now, off and on. Last time I had a complete bond failure in western red cedar, causing delamination. I didn’t spend too much time on the post-mortem, but think it was a case of bone-dry material wicking the epoxy out of the joint prior to curing.

polyurethane glues are waterproof and probably cheaper than epoxy and doesnt require mixing. Some options here

yep, i've seen this stuff melt the plastic container i was using to mix it up in. but i still have a chunk on a garage floor from some spillage that i'm yet to get off due to just how dam stuck it is. Flogging it with a ball pein hammer is the only way i can get it to move.

With respect, haveabeer, stuff what it does to a plastic container or your floor.

Focus on what it does to your insides. This stuff has serious health issues. Initially nothing dramatic but it insiduously sensitises you over time and the effects accumulate.

Quite so. The least of these is a nasty, recurring dermatitis.
