Why 502 glue makes fingerprints visible

The main component of 502 glue is ethyl cyanoacrylate (ECA), which is volatile.

strong and easy to carry out anions under alkali initiation.

type polymerization. Human sweat contains water and amino acids.

Water contains anions OH, and amino acids also contain small amounts of amino acid anions. ECA volatilizes to the sweat latent mud site, and the anionic substance in the sweat triggers its rapid polymerization to form a milky white polymer that makes the handprint visible.

Because 502 glue can solidify and harden immediately after entering the fingerprint, that is, the shape of the fingerprint is fixed, so the fingerprint is fixed.

I'll be specific. It is because of the solidification and sticking effect of the glue of 520, which causes the outermost layer of the ** on the hand to harden and then fall off.

In fact, the fingerprint is the texture of the finger, a piece of skin falls off, and it is hardened skin, of course, the fingerprint can be presented!

It is mainly the effect of glue coagulation.

There are two cases:

is still in the hand, at this time 502 wraps the finger, the fingerprint will not stick to other places, just like the effect of wearing gloves, it can be said that the fingerprint has been changed in a certain sense;

After being cleared, the fingerprints on your hands are still the same, and the fingerprints are unchanged.

PS: The subject must not think about using this method to do bad things.

Answer no, dear, you can rest assured, it doesn't matter if the skin is stained, it will grow out later, fingerprints will disappear after a long period of damage, once or twice will not be a problem. If your hands are stained with 502 glue, if the time is not long, you can soak your hands in warm water as soon as possible, after a few minutes, the glue will gradually dissolve, and your fingers can be gradually released.

If 502 glue has adhered to the hand for a long time and has been air-dried, it is difficult to remove it in an ordinary way. You can use organic solvents, such as alcohol, acetone, gasoline, etc., use these substances to smear the local ** surface, or soak your hands in organic solvents, usually after a few minutes to ten minutes, 502 glue can also be dissolved by organic solvents, and your hands can return to normal.

It's best to clean it up.

1 Rinse it down with hot water, 2 then use a nail rubbing knife to rub it a few times in the place where it sticks to the glue, and the glue can be rubbed off.

3. Then wash it off with hot water.

You can also soak your fingers in gasoline, and the 502 glue melts quickly.

However, if 502 glue is not removed for a long time, it may make your ** breathable, and it may cause a chemical reaction or **discomfort.

Removal method: 1. Drop 502 in place to melt the original 502, and then quickly wash it off with water, which is very smart!

2. With insulating oil, pour the insulating oil in the transformer on the table, and the 502 glue will quickly become soft and can be rubbed off quickly.

3. Acetone solution washable 502 glue is a kind of resin glue, as long as the organic solvent that dissolves the resin is used, such as acetone. But inhalation of acetone is toxic, pay attention to the way to use, you can stuff the adhesive part into the bottle, wait about 5 10 minutes to remove.

4. It is said that if you put it in the refrigerator and freeze it, the glue will also fall off, you can try it first5. Stick 502 glue on a small area, as long as you soak it in hot water.
