Many adhesives must also contain solvents. It is usually due to these solvents for which materials an adhesive is suitable. Superglue, for example, is also removed with a solvent. We have summarized all information about superglues and solvents here.
Basic definition of solvents
Solvents are used to be able to dissolve a certain substance. One of the fundamental properties of solvents is that they dissolve other substances, but do not react chemically with the substance to be dissolved. Put simply, a substance contains a grid, for example made of crystals, which holds it together and makes it solid.

Use of solvents
Solvents are used to keep adhesives liquid so that they can be processed. If the glue is now applied, it must be taken out of its container and applied. The solvents escape in the air and the adhesive hardens. Superglues don't work on this principle; all superglues are solvent-free. This fact makes them more environmentally friendly, because solvents often contain pollutants that are released during drying.
Difference between hardener and solvent
Superglues are not to be confused with other superglues or adhesives in general that require a hardener, e.g. a 2-component adhesive. No solvent evaporates with these adhesives. Rather, the added hardener triggers a chemical reaction and the adhesive molecules network with one another.
Examples of curing by drying or chemical reaction
Such a phenomenon can also be explained well by means of colors. As an example the following two colors:
- Silicate paint
- Emulsion paint
The emulsion paint is mixed with water as a thinner. If the paint is now applied, the paint begins to dry - the solvent, water, evaporates. With silicate paint, on the other hand, a chemical process is triggered.
For example, if you paint water glass on a mineral plaster, a chemical process is used that chemically bonds the plaster (the upper layer) with the water glass. If this color is to be removed again, the plaster must also be knocked off.
Removing superglues with solvents
Although superglues do not contain solvents, they can still be removed with solvents. Both acetone and fatty products such as oil or margarine can be used for this. Skin-friendly products such as fatty creams or oils are particularly suitable for removing superglue from the skin.
Solvent for dilution and removal
A typical organic solvent that can be used to dissolve various adhesives and also paints would be acetone. Depending on the composition, acetone can dissolve paints and varnishes, but also adhesives such as superglue.Tips & Tricks However, other possible reactions or properties are important. If superglue is to be removed from the skin, it is important to bear in mind that acetone degreases and embrittles the skin. It is also absorbed through the skin and can get into the blood. It must therefore always be clarified whether a solvent such as acetone is harmful to health.
