I presume it is PVA. I've not seen it with a yellow colour though, always white. Maybe the yellow is the bog standard stuff (I get that impression when Norm :norm: talks about it) and the white stuff if the waterproof one. Just guessing though.

No, that's not quite right. I always thought so too, and was recently put right, although I still don't know what the differences are, I just know that is is not only a case of adding some yellow dye.
The problem is that yellow glue has never caught on over here, and as far as I know there are no UK manufacturers. You can probably buy it mail order, but you won't find any in B&Q, I don't think.
I'll ask DaveR if he can throw any light on the matter.
Cheers

My very first bottle of wood glue was a Unibond (like this one, which was yellow. Worked as well as any wood glue I've ever used (I've since used Evostick white wood glue, and Titebond yellow).
It seems to be a common assumption in the US that yellow is for wood and white is for card/craft applications - although I've seen at least a few US woodworkers promoting white glue. Not sure what the chemical differences would be.

Titebond from axminster is the yellow glue, and its yellow
the pva glue as we know it here from unibond is white
I personally am more used to working with Polyurathane

I like it too for is fast curing - ready to carry on working again properties .
I'd be interested to know how you store yours ..... I find it forms a skin when the bottle is half used, if it isnt used for a few days.
what brand do you use ?

I don't know if this will shed any light or not but here's what I know. Admittedly it isn't much.
Both white and yellow glues are PVAs. The two types are low grade (craft, school or hobby glue) and high grade (professional/industrial glue). The typical white glue in the US is Elmer's school glue. In the 70s I used it on woodworking projects and never had any trouble.
Since I started woodworking again in 1999, I've used Titebond because that's what the local DIY stores sell. I haven't paid much attention to the variety of wood glues out there and I don't know if there are high grade PVAs in white but I imagine the primary reason for the yellowish color is marketing. To separate it from "school glue". The high grade PVAs cure harder than low grade PVAs, they are stronger, machine better and show less creep. They are also more resistant to water--Tite Bond III is supposed to be waterproof though I haven't personally tested that.
The term "Aliphatic Resisn" is a marketing thing, too. It was coined to separate the high grade PVAs from the low grade.
Hope that's useful.

:wink: The difference between white and yellow glue is chemical. Yellow glue has aliphatic resin added to it giving it a faster tack but otherwise had the same strength as white pva glue.
Having said that, I'm using a brand of white pva which claims curing after 10 mins and removal of clamps after one hour.
All work well, they are ony limited by the ambient temp which should not be below 5* centrigade.
cheers.

Having done some more reading, there is no difference between 'yellow' and 'white' other than the color pigment used by the manufacturer. The properties such as the high tack, longer or shorter open type is dependent on the brand of glue. Some manufacturers colour their high tack glue yellow others do not. Only the combination of the color and the brand says domething about the properties for some brands. such as titebond white and off-white for titebond I and II.
Readng the label is more userfull than reading the colour.

Aliphatic resin is, by definition a straight or branched chain hydrocarbon compound. Polyvinyl acetate (PVA, aka carpenters glue, wood glue etc etc) is, you've guessed it, an aliphatic resin. Manufacturers may put in other additives to modify open time, initial grab etc, but to say that one has "aliphatic resin" added is a bit like saying water with H2O added.

aha
I cheat, i use these
http://www.screwfix.com/prods/40778/Kit ... sive-310ml
i can trully recommend these, i have been using this stuff for over 5 years and i have completely done away with yellow or white glue
I still have 2 gallon bottles here from titebond, and i hardly use it.
the ease of use of the polyurethane is so much better
but one word of caution...always were gloves

Thanks George N
that sounds logical but permit me to quote from an article by John Lloyd in the May issue of F+C : " the only yellow glues that I have come across in the U.K are made by Titebond and and my understanding is that Titebond original and Titebond 2 are PVA's that have an aliphatic resin added to them "
Its not a bad article and of course I was quoting from him. Personally I prefer yellow glue .
cheers.
