Technically, Elmer's Glue-All is a “PVA-based glue”, but it’s basically like all regular PVA glues. There isn’t much difference between Elmer’s and the regular PVA adhesives, in my experience. Elmer's Glue-All was probably modified from regular PVA glues to enhance its properties (strength, tackiness, viscosity, odor, etc.), ease of use, and safety.
As far as the mild acidity of Elmer's Glue-All, this shouldn't be a problem when used with paper. Cellulose, the main structural component in paper, wood and cotton, contains several hydroxyl groups on each of its monomers. This is ideal for acidic PVA adhesives because the PVA's acidic hydrogen ions (H+) will strip away hydroxide (-OH) groups from the cellulose molecules, and create water (H2O) molecules. With the H+ and -OH molecules removed, the PVA polymers will create strong bonds with the cellulose polymers. This is why Elmer's Glue-All is *mildly* acidic: the acid helps drive the PVA-cellulose reaction, but it's not acidic enough to adversely affect the cellulose or the PVA.
The acid will not break down the cellulose over time. Any remaining acid will become neutralized as the glue dries out and therefore the reaction will be complete.
Acids with pHs above 4 are considered to be mildly acidic. Elmer’s is designed to be safe for children. Listed below are the approximate pHs of many common substances. (Sources: various pH charts on the Internet while Googling for "common substances pH" and “beverage pH”)
pH = 7: pure water
pH = 6: milk, tea, well water
pH = 5: yogurt, brown sugar, Perrier, Aquafina, purified water, distilled water, coffee, Pepto Bismol, rain water
pH = 4: tomatoes, orange juice, grapefruit juice, red wine, Gatorade G2, Snapple Red Tea, acid rain
pH = 3: many sodas (Coca-cola, Pepsi, Dr. Pepper, Sprite, Mt Dew, Red Bull, etc.), beer, Vitamin Water, Dasani Plus, vinegar
pH = 2: lemon juice
pH = 1: stomach acid
pH = 0: battery acid
I've used Elmer's Glue-All on many paper projects for years, and there's never been any degradation of the paper. If anything, Elmer's has made the paper STRONGER. (Note: Elmer’s Glue-All slightly “clouds” the paper but ALL glues do this. The slight clouding isn’t due to acidic deterioration. The clouding is because Elmer’s Glue-All is opaque white in liquid form, but it’s ~99% clear when dry. The clouding is barely noticeable.) I use Elmer's Glue-All because it's safe, inexpensive, strong, easy to use, and it can be found at many stores (Wal-Mart, Michael's, Office Depot, etc.). I've used several different PVA brands, but their properties are fairly similar to one another, so I tend to use Elmer's the most because it works well and it's inexpensive.
I don't claim to be an expert on PVA adhesives but I have a Materials Science background (B.S. and graduate school; my emphasis is in alloys and ceramic materials, but I've taken some polymer courses). While I’m not a PVA adhesive expert, I understand the chemical mechanism as to how Elmer's Glue-All reacts with cellulose. In addition, I know Elmer’s Glue-All is safe with paper because I’ve been using it for years.
Btw, I don't work for Elmer's (nor have I ever worked for any PVA adhesive company), so I'm not trying to sell Elmer's Glue-All. My main point of this message is that Elmer's Glue-All is a good, safe, general-purpose adhesive for paper projects. If you're afraid of Elmer's Glue-All because you think it's harmful or because you thinks it’s a cheap kids glue, then don’t use it. Also, if Elmer's Glue-All is in fact harmful then PLEASE PROVE IT with facts/science/experiments/experience/whatever.
(Note: The reason my message is long is because I wanted to write a full explanation as to why I think Elmer's Glue-All is safe for use with paper. Seeing as how I've come across this thread six years after it was created [via Google] and seeing as how this thread has been viewed over 170K times, this thread will continue to be viewed for many more years, with thousands more views. I don't have any interest in checking on this thread so I wanted to post my opinion and move on.)
so you could use normal school glue?
Those other ingredients will cause cancer. Or obesity, or both if the user is a paste eater....Yuck!
I did some research and found that elmers has an acid free glue. Reviews say that it can be used on paper. What would you say?
Question, someone suggested I could coat plain craft foam(purchased at Michael's) in PVA glue. I suppose Elmer's Glue or something similar will suffice. Well, my question is, will it damage the craft foam at all?? My plan is to simply coat it all before painting it with acrylic paints. The whole point is so that the acrylic paint won't crackle or flake off :/
modpodge will give you a waterproof seal, an option of glossy or matte texture and save you on paint since the acyrlics won't soak so deeply into the porous texture of the foam's surface. ??? Best Wishes'
yup' See comment/my reply above.... ??
If you believe it took hundreds of thousands, or billions of years sure. Otherwise 5,000 years isn't very long at all. But I guess in the scope of our short 50-80 years on this little blue mable 5,000 could seem like a while, but it's really not that long at all. ;)
I'm not sure what the heck you're going on about, but it doesn't seem relevant to this question.
Yeah, back in 1947 WHEN IT WAS FIRST INVENTED....
NOT in this day in age.
They have grown to use more advanced materials over the last near-70 years....
I've been using Elmers glue mixed with food colouring to create a sea glass effect on clear glass objects, but I've discovered that PVA is much cheaper. Will it do the job - does anyone know? If not, I'll just have to buy some PVA and experiment.
Speaking as a mother who has a kid that would rather make crafts than go out and play. Seriously they had to make her stop to go out for recess. I have paper crafts that my kid made 10 yrs ago with elmers that although they are dusty the paper has not broken down and my daughter used ALOT of glue. Not a scientist though. I have a major in Science and accounting intending to go into forensic accounting. Somehow I ended up in the financial sector. At any rate I have young boy who is now 9 and loves science projects. So on that note he wants to make crazy putty which calls for PVA glue. Would elmers glue all work for that or am I going to need to hunt down a bottle of PVA Glue. I am going to use this for a cub scout activity and would really like this to work out.
Holy-Cow! This has over 150K views!
I used PVA glue to seal a craft foam ball several years ago and then covered it with mosaics. That worked well but it did take several coats of the glue to seal it.
White school glue is just fine. No worries.
Than you vbanaszak for your reply.
PVA = Polyvinyl Acetate...Don't worry about the brand name. It's essentially white craft glue. "Elmer's", actually has a higher than average Ph than most PVA's and depending on the wood you plan on using, it might cause staining...hope this helps.
Thank you Jim for your reply. Yes it did help.
