I'm not sure if this is a word of caution or complaint...
Has anyone bought and used the 2 part "Rapid" epoxy sold by B & Q under their own brand name?
My local stockist being temporarily bereft of my usual "Araldite"...well, when needs must and so on
The front of the packaging advertises "5 minute bonding". Sounded OK, so parted with £4 of my pension.
As 99.99% of you will know, Araldite comes in a thickish opaque "white" stuff out of one tube, and a thinner, clear stuff out of the other tube. Not so with the B&Q product. Both tubes eject a clear "goo", and when mixed remain "water-clear". That's odd, says I.
Still, being a trusting sort, I carried on with the "job". 4 hours later this "5 minute" stuff was showing no signs of sertting. Now I began to wonder if both tubes were filled with the same stuff. Black cap and White cap. Both clear gloop.
Then I looked at the small print on the back of the packaging.
"Handling Time" is 12 hours.
Full strength in 24 hours.
Sort of makes a mockery of the "5 minute bonding" as shouted on the front of the package. I'm seriously miffed about this.
Perhaps the 2 tubes are filled with the same stuff? Either way it's causing me more problems than I either expected or need.
So beware of B&Qs alternative to Araldite. BY.

I'd take it back. If it said 5 minute and was not it breaches the Sale Of Goods Act.

Neil, if it eventually sets then I'll be happy. All I was ryting to do was give a warning to a buyer who expected an Araldite substitute.
Although....the word "Litigation" comes to mind! I can see my B&Q "pensioners card" being voided now. Bryan.

I've had some of that clear glue too. Very annoying. It did eventually set but not for a very, very long time.
Normally, I buy slow epoxy anyway as I want the stronger bond but when I want it to go off quickly, I want it to go off quickly. <*< >>:-(

I prefer using acrylic adhesives now. They're about the same price, but the acrylics stick just about anything, less fussy than epoxy, and totally waterproof. They set quite quickly, so if you want long handling times, better to stay with epoxy (24hour cure). Devcon plastic welder, Stabilit Express, Deluxe materials Super Crylic and Fusion.

I wasn't even aware that there was an acrylic alternative.....not that I'm surprised now that I do know.

OK, give me a name (product) for this super-duper acrylic stuff.
When I'm not using the equally good super-duper double-sided tape, I'm always on the lookout for other stuff. Thanks BY.

Hi,

No! Because all epoxies are not poxy. Sorry about that. Bryan.

I already gave three brand names of acrylic adhesives in my original post. They all differ slightly. I'd say go for Devcon Plastic welder if you want an epoxy alternative.

Oh I totally agree Bryan, was just trying to iject a little humor, but obviously failed miserably!

Sorry about that....once again I chose the wrong words! What I should have said was how do you know they are acrylic? My Axminster catalogue mentions the Devcon, but omits any reference to being acrylic. Obviously I'm no chemist, but for some reaso I have difficulty reconciling "epoxy resin" with being water based.

No... you didn't fail (miserably or otherwise). In fact there's more than a little truth in what you said. Regards. Bryan.

Because I researched it on the Devcon website.
All these adhesives are methyl methacrylate based. Here are some datasheets-

Also Starloc adhesives do a version calle superacrylate. Only recently discovered that, so i haven't tried it yet, but price is competitive, and I've found their other products excellent, so I'll probably go for that next time I need some glue.
