Is the combination of soda and superglue really so reliable? Let's check

Probably every DIYer or DIYer already knows that if you sprinkle super glue with soda when gluing something together, the joint will be much stronger. But is this really so? What happens to superglue when it gets mixed with baking soda? By the way, you can use finely ground table salt - extra - instead.

Testing baking soda in combination with superglue


Place a small mound of baking soda on the surface. Let's pour super glue on it.

Immediately everything froze. By the way, heat is released and everything heats up. To check the strength, hit the formed tubercle with a hammer.

Quite reliable. No cracking or chipping. If, of course, you strike normally without fanaticism.
Next, pour baking soda into a matchbox and also add super glue.

Let's try to drill and tap the resulting rectangle.

At least you can’t just rip it out with your hands.

Surface gluing


There is a plastic watering can with a crack on the side.

Let's first seal the spill with superglue on the crack.

And then sprinkle with baking soda.

We check the tightness by filling the watering can with water.

Everything is dry, no leaks!
Next, we glue the broken plastic together using the same method.

In the end, everything is held securely.

Conclusion:


Yes, indeed the connection is much stronger than using just superglue.
Repairs based on such gluing are quite suitable for assemblies and parts where there are no significant loads.
Another huge advantage is that hardening occurs instantly compared to glue based on epoxy resin, although soda and superglue are inferior in hardness. But compared to epoxy, super glue has better adhesion to the surface being glued.

So for quick repairs, I personally don’t know a better and more reliable method yet and I always use it.

    All this is bullshit! I glued the crack on the gearbox and the oil was still expelled.

    Cyanoacrylate with polyethylene has practically zero adhesion (the watering can is made of molded polyethylene, so its tightness is in doubt), the same is true in the case of gluing plastic into a joint.It will glue PVC without problems, polystyrene, composite, aluminum, natural fiber fabrics, leather. But polyethylene or rubber - no. Polyethylene is specially placed under the product to be glued so that it does not stick to the surface. Soda to speed up the reaction so that the acrylic sets faster (acrylic in this glue is a plasticizer).

      Not only. Small specks of soda dust increase the bonding area and density, and not only speed up drying.

        Does it increase the area? Are you sure you are sane?

    Of course it's bullshit. You can use this thing to glue places where there are no deformations and not on all materials. But not like a watering can or a plug for a car door handle. This is a “half an hour” repair.

    I glued three radial cracks on a car bumper. I drilled 1.5mm holes along 2cm and filled them with superglue and soda. Sanding, priming, painting. Three years without problems. Almost unnoticed.

    In the store they already consider me a drug addict - I buy glue often. I glued a lot of things on my scooter with baking soda quite successfully. In model making, this method is generally irreplaceable; it quickly allows you to glue, fill cracks, unnecessary holes, etc. It should be taken into account that glue with soda does not immediately gain strength. Use the technique, don't be afraid

    It’s a good way, I’ll give it a +, it’s been verified, I do it too. Well done!

    Guys! We have been restoring hinge fastenings on laptops this way for several years now!
    out of 100%, a maximum of 5% was returned!

    I glued it with regular plastic. Absolutely non-working instructions. As a result, I decided to look for other adhesives. Superglue, whether with soda or without soda, is a threshing floor
