White Spirit Uses, Substitutes, Ratios: Mineral Spirit, Technical Alcohol, Evaporation & Drying

Hello.

On the English website I found a description of the process using white spirit.

This is translated into mineral spirit> can it be replaced with any technical alcohol?

Is the other name of this product white spirit?

The technological thing is that we add quite a lot of this solvent to the mixture with the hardener. Practically 1/2 of the solvent and 1/2 of the mixture.
Sometimes the ratios are higher than 3: 1, 4: 1, and 5: 1

After 24 hours it cools down to something with the consistency of a thin jelly.
The next step is to evaporate the solvent so that we have a micro sponge with something like an airgel. With invisible micro solvent bubbles.

What thinner to use so that it evaporates as quickly as possible.
Guests also recommend using a mushroom dryer in the process.
All drying takes from 1-4 weeks. Maybe even longer if the object made is larger and the solvent evaporates longer.

Not mineral, white spirit, in the sense of being pure.

It is so and so translated.
But is it the same as alcohol?
According to the wiki, it is made of petroleum.

It is supposed to be cheap, but it is 2 times more expensive than ordinary solvents.

In total, I do not know 1l of spirit costs PLN 2 in production and this is sold for PLN 10 per liter. Twice as expensive as common solvents.

Give a link to what you want to do.

White Spirit is the most common solvent for oil paints and has nothing to do with spirit as alcohol. It is a kind of purified and properly prepared kerosene rather than alcohol.
The word spirit (spirit, soul, vapor) is used here in the sense of volatility and evaporation, and not in the sense of alcohol as a spirit.
The size of the particles is within the limits of C9-C12

White spirit, that is?

Probably not.
This is closer to the ordinary solvent of phthalic paints.
I am always annoyed by the fact that manufacturers do not provide chemical formulas of their products, but invent different names that often do not even have anything to do with the product itself, and besides, despite the health and safety warnings on the labels, this increases the risk of making a mistake in using a given product, which may be unexpected way to cause some dangerous chemical reaction.

Nonsense! Don't mislead people!

So white spirit?

This is something between extractive gasoline and white spirit.
The extraction gasoline consists of C5 - C7 hydrocarbons, white spirit C9 - C16 and mineral turpentine C7 - C12.

What to buy?

This is where the problem is that they are usually mixtures with different proportions of individual hydrocarbons and without the manufacturer's chemical markings, you will not get exactly what it is, or how much of which ingredient and in which fractions.

As it results from the description in the first post, any of the solvents should pass the test, and the difference will be only in the rate of evaporation, because the solvent itself does not take part in the reactions and is only a filler for evaporation.

I found a video of what I mean


And it would be best for it to steam as quickly as possible, because waiting a month to see if it works out is a terrible waste of time.

And the regular IPA?
The smell is bearable, evaporates quickly, leaves no traces?

Here you are. Odorless white (mineral) spirit:
26.5PLN / liter You will find cheaper in wholesale.

In Polish, odorless white spirit, odorless mineral spirit, etc.

In this shop, someone has got something mixed up, because the word alcohol in Polish means alcohol. It can be practically any alcohol from methanol onwards.
There is also one of the groups of solvents, unfortunately it does not mix with oils used in oil paints.
The only possibility that what they wrote in the store was correct is that what they offer is undyed denatured alcohol, i.e. methanol, which I often use myself.
Nevertheless, the name white spirit does not in any way refer to alcohols, and all this mixture of translations in the description comes only from the ignorance of the person describing the product.

English traces have happened and will happen. We will not avoid it.
Spirit is ethanol. Wood spirit is methanol. White spirit is the solvent we are talking about.
Denatured alcohol is ethanol denatured with denatonium benzoate (the most bitter chemical) and butanone. Methanol has been gone for several decades.

The faster the evaporation, the larger the pores.
In addition, you must have a solvent that will mix with your mixture. I don't think alcohols are suitable because of the electrophilic center in the molecule, so they can react in the environment. Besides, I don't know if they will mix.
You can try hexane or gasoline, but the bank will get much larger pores than you would with the current solvent.

As for me, the smaller the pores, the better for the casting.

Here you have cheaper -19 PLN a liter, a top-quality product that has been used for years:
Fiddes White Spirit .
I also recommend it for pcb as a cleaner, you can quickly put aside the lower-quality IPA that is available on our market

Hello,
gentlemen, the discussion looks strange, a few problems to consider:
- white spirit is a mixture of saturated hydrocarbons, which is closer to gasoline
- since it is a solvent in the process like soot cross-linking of the resin, the solvent cannot be active, so the alcohols fall off as they can participate in the reaction and thus affect the properties of the final product. This has to be checked on the basis of the reaction in the system.
- modification of the process itself, I would be careful here, changing the conditions will change the properties of the product.
