Topic tags/keywords: glue

I am looking for a glue that I can use to adhere magnets (little round disk type) onto wood and plastic. (Acrylic, if it matters.)

I did my testing with some of that low-expand gorilla glue and it still expanded a lot (but the magnet sure is not going anywhere! :) ) and yesterday I did some tests on plastic with generic CA, which sure stuck it good but it also kind of went everywhere, which wouldn’t have been noticeable on wood but on the acrylic you can see it clearly.

So I’m thinking a gel glue would be good? Any brand of gel CA work the best in y’all’s opinion? I need A LOT of whatever I use, so I would prefer to buy it in slightly larger containers than those teensy tubes they sell at Hobby Lobby. (And I don’t mind buying online!)

Thanks, guys!

You might also consider System Three Gel Magic. It’s a two part epoxy. Really nice to work with.

Lis, I prefer the titebond brand. There may be better brands out there but I haven’t run across them yet. They come in 2 and 4 oz containers. I bought the 4 oz container thinking I would save $ and time cause I use a lot of it too, BIG mistake! The tip hole is slightly larger than the 2 oz size and you usually get more than you want out and is harder to control the amount you use. Also the tip being larger leaves a slight amount on the tip as spillage and when you put the cap on it sticks to the cap and requires periodic cleaning and that tends to ruin the threads on the cap and I usually waste about half of the 4 oz size. The 2 oz is much easier to control and I get much less waste. It comes in 3 forms thick, medium, and thin.

As for the 2 part epoxy, I have used it once and found it time consuming and messy. It may be that I did not use it right or have enough knowledge in it’s usage. I do know that it has good properties if used appropriately.

Good luck and nice seeing your icon back on LJ.

Liz,
I have not had that much luck with CA used to bond polished metal. Seems to come apart after a while. I will agree with Bearpie about the Titebond brand. It works well.

I have had much better success with epoxy. A little lacquer thinner is good to de-grease surfaces before bonding and works for cleanup as well. I like the System 3 products, but that is the only professional brand I have tried; the rest were what ever they had at the Walmart or Home Depot the day I was shopping. They all lasted longer and gave a more powerful bond than any other type of glue I have tried on polished metal.

Bearpie, What I do with some glues is simply transfer some of the glue I buy in bulk to smaller used containers.

for the original post, I’d second the idea of epoxies or a CA glue. Also remember, gels are nice, but they rarely penetrate as well as something more…. “runny”.

CA glue comes in different viscosities – thin, medium and thick. I use the thick CA glue when gluing magnets.

If I am working with round magnets, I usually drill a shallow hole the size of the magnet and glue the magnet into the hole.

You might give hot glue sticks a try, not sure how it would turn out but it is clear..

I was thinking gluestick myself. They have some high bonding varieties out there now & you can buy sticks by the ton if you like.

yeah, hot glue is surprisingly strong. I’d suggest that or epoxy.

Bobthefish, I have tried buying the larger container and transferring into the smaller container but the problem I had with that is the smaller container is good for only one transfer before the threads are “ruined” (at least for me) and I would still have to buy another small container and use that up and use the second half of the larger container. Much simpler to just use the 2 oz container.

On another note; I used the thick glue to glue a board to an rectangular aluminum tube that I use for re-sawing to prevent the aluminum transferring grey marks to the wood I am cutting due to vibrations of the saw. It worked well till I went on vacation for a week and came back to find the board laying on the floor, I had to drill and screw the board to the aluminum tube. Seems the glue did not adhere well to the aluminum as there were very little glue on it and most of it was on the wood.

Thanks everybody! :) I will look into the different choices suggested here and see what works for me. I am hesitant to try hot glue because I use low-melt glue in the shop everyday (to hold down pieces while I cut them on the CNC) and I can totally see myself mixing up the two, even if I dedicate two different glue guns to the task. (I’m talented like that)

I generally do them in big batches, so some of these choices look awesome!

I usually scuff up the magnets and use 5 minute epoxy and had no problems thus far.

I’ve read that rare earth magnets are coated with something (I think they are a bit brittle), so scuff them up, as noted previously, to give the coating some texture for the glue to bond with….

and when in doubt, use epoxy. (I understand that once textured, CA should work fine)
