Liquid glass or ceramics, what's the difference?

Among car enthusiasts, the choice of means to protect the paint, the question often arises: what to choose, "liquid glass" or "ceramics"? The same products with just different names? There are articles exposing the composition of "liquid glass" and describing it as a long used in construction, but with a much lower cost. Whether so it actually. Let us understand what is "liquid glass" to protect the paint of your car and how it differs from the ceramic protective coating.

Can just say that "liquid glass" used in construction, has nothing to do with automotive protective coating. It has the formula Na2O(SiO2)n or K2O(SiO2)n. And is also known as silicate glue. In addition to the presence of silicon dioxide, this composition has nothing to do with a protective composition of the paint. In automotive coating SiO2 particles have a smaller size and shape, as well as there are additional components affecting the formation of the film, increases the UV protection and other properties required for a protective coating.

What is "liquid glass" for vehicles?

Liquid glass

To understand what "liquid glass" for vehicles, first consider what types of protective coatings coatings are. They can be divided into waxes, sealants and permanent coatings. Ceramic coating belongs to the third group of protective compounds. That is, it is applied once and remains unchanged for long term. "Ceramics" penetrates into all the cracks and uneven paint coating and firmly fixed. This coating is an additional layer that resembles varnish, but having other properties.

It is also necessary to clarify that the concept of "liquid glass" became a household word and a protective part can be called "liquid glass", although on the packaging there is no such name. In English, "liquid glass" is "liquid glass", and the packaging is often possible to read the "glass coat", which can be translated as "glass coating". In this case, the word "coating" identifies this part to the type of permanent coatings.

Thus, it is important to understand what type of damage coverage, regardless of its name. Different brands of this product may have a different composition. So, for example, "liquid glass" (which in this case is translated exactly) the American brand has in its composition SiO2, known as a component of glass and ceramics. This Polish is sold on the American market for over 25 years. This "liquid glass" is positioned as a protective wax and can be washed off, unlike ceramics, which is a permanent indelible coating.

Such polishes "liquid glass" can be attributed to synthetic sealants. Their composition is a polydimethylsiloxane (silicone). This is the same component that contains the protective equipment for tyre and other auto-cosmetics. Silicone is used as a component to form the film. The protective layer is obtained enough proof, gives UV protection and Shine, but is on the paint surface and does not penetrate into it (like ceramics).

What is SiO2 (silicon dioxide)?

SiO2 is the most commonly in nature as sand or quartz. The sand is still one of the main ingredients of which glass is made. Ordinary glass contains 70-74% SiO2. More than 90% of the sand consumed each year is used in the glass industry.

Hydrophobic coatings can be formed from different components and not only of SiO2. Protective coatings on the basis of SiO2 are common, as are the most cost-effective cost-effective and easy to apply.

Products from different manufacturers may contain different percentage of silica. Good product contains more than 50% SiO2, but not every manufacturer specifies this value.

What's the difference between "liquid glass" from "ceramics"?

As described above, a "liquid glass" nano-ceramic coating can be completely different products. The first relates to the protective coating or coatings having constant communication with the LWA.

If we consider similar products with different names that belong to the same group of permanent protective coatings, the differences can be used in the structure of the SiO2 particles, their number and the presence or absence of the binder polymer and various other additives.

So, "glass coating" (eng. Glass coat) and the "ceramic coating" (eng. Ceramic coat) can have the same composition, but different structure of SiO2. Ceramics has an ordered structure of molecules and the glass chaotic. Glass is known as an amorphous material having no crystal structure (as in liquids). You can turn the glass into ceramics by heating. This will distribute the atomic structure of random in an ordered, more stable. In the name of some of the coatings mentioned the word quartz (Quarz). It has a crystalline structure. This is a more expensive option glass coatings (Quarz glass coat). This structure provides exceptional strength and resistance to chemical attack and increased resistance.


Thus, coatings based on ceramics or "quartz" are more resistant than the coating with silicon dioxide (SiO2) that have no orderly crystal structure.

Another criterion of the effectiveness of protective coatings is the presence or absence of the binder polymer in the composition.

Protective coating, having in its composition a polymer which is a binder for the solid particles, are less resistant than the coating without him. This composition is traditional, but has drawbacks. This polymer is gradually destroyed chemically active substances and physical factors. The polymer is the weak link. A good ceramic coating has a polymer and better protects from chemicals, as they have to break solid components (SiO2, SiC or TiO2), and not the polymer.

In conclusion, we can summarize that the important type of protective product and its composition. When it comes to "ceramics", what is meant is long-term coating having constant communication with the LWA. Good "ceramics" with the right application and future maintenance can last from 2 years or more. "Liquid glass", as mentioned above, may be protective Polish, which has no permanent connection with the LCP and will last from 6 months to a year, depending on the amount of cleaning and it will be worse to protect from minor scratches. Again, a "liquid glass" as a common noun phrase may also denote a permanent coating. In this case, you need to specify the composition of the product and its properties.
