Make clear bond more fluid or not ?

You can add 99% alcohol....It will reduce bond time, as you're diluting it.

No, actually. You are adding more solvent, which will make it take longer to cure. Once the alcohol has evaporated, it's the same bond time. I still wouldn't do it.

Not true. You're adding more isopropanol,which inturn changes the ratio and alters the chemical composition. You are also likely adding water to a compound that was formulated with zero water.
Mighty tite and ultra hold have identical ingredients yet Vasily different advertised hold times.... This is because there is a higher quantity of isopropanol and a different ratio of ingredients..... So, adding a small amount of 100% isopropanol (at best)... would weaken it to the level of mighty tite..... more would make it even less effective. Adding a solution (rubbing alcohol) that contains 1-9% water is certainly not good. You'll also start to turn the adhesive cloudy the more you add.

I guess if the 1% is water, that could be true.
If you are adding 100%... why would that make a difference, since the 100% will fully evaporate? Also, do you know all of the ingredients in both of these adhesives or just the "main" ones? Just wondering.
Again, I still agree that it's not a smart thing. Just interested...

Where would you acquire 100% isopropanol? It's not commonly available to the public.I guess if the 1% is water, that could be true.

It changes because you're altering the chemical composition, it's no longer what it was....A tablespoon chocolate and a cup milk combined is very different than a cup of chocolate and a cup of milk combined. One would have the consistency of milk and the other would have the consistency of mud. They would evaporates and spoil at different rates . They would have and maintain different temperatures. There were be nearly a dozen significant differences between them.
Think about putting 5 gallons of chlorine in a pool instead of one. The lower concentration would safely inhibit bacterial growth... the other would kill fish, damage, hair, skin,lungs, and eyes.....
Yes, all of the ingredients are publicly available, and listed in desending order starting with largest quantity.
Isopropanol, Ethyl Acetate, Heptane, Toluene. If they were not listed, the company would be in violation of statue 15 U.S.C. 1451-1460
Balance is just as important as ingredients, if not more so. Chemotherapy kills cancer and save lives .. A different ratios it would be either less effective or deadly to the patient.
Much like potassium. It is taken as a supplement and prescribed by physicians worldwide. It Promotes proper function within the body. However it's also used On deathrow to end lives via lethal injection. The only difference being the concentration administered...
Business wise, if Walker could add a fraction of a penny worth of extra isopropanol to their .5ml $9 bottles .....increasing the size by 50% to. .75...they would more than double their profit for next to nothing. Why wouldn't they if everything else remained the same...... They found this to be the best combination at the best ratios for its intended purpose. If a different ratio worked better they would charge a premium and sell it. If a different ratio worked less well... they would produce and sell it cheaper, marketed to those that desire less hold time. Which is exactly what mighty tight is.....

As I've stated multiple times. The concern is not evaporation, it is changing the chemical composition, and the addition of an unintended ingredient.
As I've stated you can add a few drops of 99% alcohol and use the adhesive. What I'm pointing out is you will not get the exact same results as you would within unmolested version.
Every action has an equal and opposite reaction. You are studying to be a physician, correct? You should know all of these things.... As they are all basic fundamentals of chemistry and science.
This is much like a mirrored version of insanity. You can't do things differently and expect the same result. Just like you can't do the same thing and expect a different result.....

Thanks for your oppinions.
As you know Walker tape has this 42 ml (?) packages. The bottom fourth is really hard to reach with the brush and if the glue is older its just some kind of sh*t that you get out of there.
So at all I sprayed some 99% iso in it and its fluid again. It doesnt matter if I have some less bonding time, I would never reach 3 weeks or so even with this.

Other then reduced bond time everything else should remain the same. Personally I change to a new bottle when the old one reaches half, to keep it fresh.

Ouch.... Can't put a spending cap on vanity.
But seriously, no problem putting a little 99%, I've done it too. My Mega paragraphs are more correcting the stament that it wouldn't change anything .... or course change....creates change...haha and everything comes at a cost....or with a tradeoff.
In this case..... a minor one.

I understand that it's just adding one more component and that's it. When the bottle is closed, it's there, but when it gets in the air, it's going to evaporate right away and how is the composition so different then? I'm more thinking about water based white adhesives, though. Maybe the solvent based ones will somehow bind or maybe even react with the alcohol, but I doubt. The adhesive becoming tacky is because of the evaporation of all the solvents in solvent based and in water based adhesives. They leave the system. Even if toluene somehow layers with alcohol, it will still evaporate and then why not let the alcohol evaporate?
I'm studying to be a specialist physician yes.

Thats my point, it's not an evaporation of all solvents equally. I am sure you know, each solvent has a different evaporate rate. The chemical itself and quantity used will determine if and how it evaporates.
So for example....if heptane decreased by 15% and touline bu 10% via evaporation and you add 10% more isopropanol.... You just made it a completely different product than it was created as. Will it work as an adhesive?Depending how much you add .. It likely will. However, it is not the same as the product you purchased.... It is a completely different chemical composition, and one would be foolish to expect the same results from the newly concocted product.

The words "really" and "anyway" have no place in chemistry. Haha
