I was thinking it would be helpful to provide examples of PVA glues. I know Elmer's Wood Glue and Gorilla Wood Glue are pretty popular as far as wood glues go. Noodle24 (talk) 12:39, 30 March 2011 (UTC)[reply]

PVA vs. aliphatic resin emulsion[edit]

What is the difference between ordinary PVA "white glue" and aliphatic resin emulsion "carpenter's glue" or "Yellow glue"?-96.237.78.13 (talk) 13:11, 17 August 2010 (UTC)[reply]

I think a whole section on PVA glues and their various compositions and properties is warranted. I wonder about the "waterproof" PVA glues like Titebond III, and how others keep microbes etc from attacking. And Mod Podge? --2602:306:CFCE:1EE0:119E:8A:FB6B:2807 (talk) 09:20, 3 December 2017 (UTC)x[reply]

Confusion between Alcohol and Acetate[edit]

There are repeated references to Poly Vinyl Alcohol in this article, which is about Poly Vinyl Acetate. I think this is due to the natural confusion between two things usually abbreviated as "PVA". I think they should all be reverted to Acetate, but I'm hoping someone more versed in the actual chemistry will chime in.

If this isn't the right solution, I'd appreciate a clear explanation of the relationship between them, with links here and from Poly Vinyl Alcohol. --2603:3024:1405:D00:89B1:A100:27EE:544B (talk) 02:49, 27 March 2018 (UTC)[reply]

Solubility & Toxicity[edit]

I have come across a PVA string which is claimed to be soluble in water and safe: http://vi.raptor.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=123939270770&category=179972&pm=1&ds=0&t=1573990848343

Is this the same material? Is the plastic soluble and harmless? IS the glue, when set, soluble and harmless? FreeFlow99 (talk) 11:51, 17 November 2019 (UTC)[reply]

If it's deliberately soluble in water, that'll be polyvinyl alcohol, not polyvinyl acetate. The two are widely confused. I've no idea why we haven't worked out a rational pair of distinct acronyms for them by now. Andy Dingley (talk) 12:05, 17 November 2019 (UTC)[reply]

Thanks Andy. However I don't see a reference to solubility in the polyvinyl alcohol article (perhaps it needs improvement), though I do see a mention of soluble polyester in the polyester article. I agree that we ought to stop using the term PVA for the alcohol and use PVOH instead; even if we only do that within Wikipedia to avoid confusion.

PVA Glue Setting[edit]

Please would someone knowledgeable add information about how PVA glue sets ? Does a solvent dry out, or does it react with air or moisture ? Thanks for any help ! Darkman101 (talk) 08:34, 22 August 2020 (UTC)[reply]
