Are acetone and silicone compatible?

Acetone is a thinner that can dissolve or at least attack various plastics. As it is a popular cleaning agent, it often raises the question of how acetone behaves to silicone. The following guide will give you answers.

What is acetone?

Acetone is an organic solvent. It consists of the simplest ketones and is therefore water-soluble. In addition, it is rapidly biodegradable. In the form of raspberry acetone it even occurs in nature in raspberries and is responsible for their typical smell.

Do not underestimate acetone in its effect

Nevertheless, you should not be too careless when dealing with acetone. On the skin, acetone causes rapid drying and embrittlement. In addition, acetone is slightly toxic. Not to mention the slight flammability of the acetone vapors in the air. Therefore, caution should be exercised with acetone in each area:

  • in use
  • while storing
  • when disposing

Acetone and plastics

In addition, acetone is completely different on different plastics. For example, polystyrene (colloquially known under the trade names Styrodur and Styrofoam) completely decomposes it. These properties are also used, which is why acetone can also be a component in plastic adhesives.

Acetone and silicone, for example because of mold removal

Since it is an excellent degreasing and de-oiling agent, acetone has also been successfully tried out in other areas. Thus, acetone is also excellent and efficient against mold. However, this raises an important question, because mold often occurs in wet rooms or on windows, including where it is silicone.

Distinguish between genuine silicone and other sealants

So what about acetone and silicone? Compared to "real" silicone, ie silicone rubber, there is no chemical reaction. However, many other pasty plastics are colloquially or falsely referred to as silicone - such as acrylic. So you really need to be sure that it is silicone.

Silicone does not react soluble on acetone

Thus, silicone is also completely contrary to the widespread assumption that it can be removed with acetone. Genuine silicone can not be removed with acetone. However, as a result, mold can be removed from silicone with acetone.

Tips & Tricks

Incidentally, not all metals are resistant to acetone. On copper it can come to pitting, aluminum, however, does not react to acetone. So, if you want to degrease a metal and then paint it, you first need to examine how that particular metal will react to acetone.
