PVA or PVAC glue

PVA is polyvinyl acetate.  Ac is an organic chemistry abbreviation for acetate.

Changing Ac to AC is probably advertising hype.

 

I see five types of PVA:

pH neutral (pH7)  bookbinders - good for cotton or linen rigging

white - dries clear

yellow - wood workers - dries amber - is acidic

Titebond II - yellow - water resistant - dries amber - is more acidic

Titebond III  - brown - water proof - dries brown - is a lot more acidic

 

white or yellow is probably sufficient

Titebond II if you are compulsive

Titebond III if the model is to be aquatic - otherwise probably not worth the negatives

 

I doubt that there are that many companies that synthesize the base chemicals so most name brands are probably different names on containers of the same stuff.

The 'Ac' in PVAc stands for acetate and  PVA for alcohol. I am unsure of the difference in the properties or pH of each, though. Perhaps someone else can inform us.
