In recent years, the detailing industry has been filled with marketing terms, of which the word “quartz” stands out. Many car owners are wondering: quartz for a car - is it just another sales trick or a truly revolutionary material? If you are looking for a way to protect your vehicle from the aggressive environment of the metropolis, but are confused by the names “ceramics”, “liquid glass” and “quartz”, then this information will help clarify.
In fact, under quartz coating Most often they understand compositions based on silicon dioxide (SiO2), which is the main component of ordinary sand and quartz. However, in automotive chemistry it is not just ground sand that is used, but complex chemical compounds obtained by polymerization. It is these substances that create a super-hard film on the surface of the varnish, which radically changes the performance characteristics of the body.
The main thing you should understand right away: quartz coating is not armor against serious mechanical damagesuch as impacts from branches or gravel at high speed, but it copes well with micro-scratches and chemicals. Unlike traditional waxes that wash away in a couple of sinks, quartz reacts with the paintwork to create a long-lasting layer of protection. Let's take a closer look at how it works and whether the game is worth the candle.
Chemical composition and principle of action
To understand the essence of a product, you need to look into its molecular structure. The basis of most modern protective compounds is silicon dioxide. In the liquid state, this material is in the form of precursors, which, upon contact with air and moisture, begin the polymerization process. The result is a rigid three-dimensional mesh that is firmly bonded to the surface of the body.
The curing (or “drying”) process can take from several hours to several days, depending on the specific brand coatings. At this time, the composition reaches its maximum hardness, often reaching values of 9H on the Mohs scale. This makes the surface resistant to small abrasive particles that are inevitably present on the road.
⚠️ Attention: Application of quartz composition requires ideal surface preparation. If dirt or grease remains on the varnish, the coating will lie unevenly and will peel off quickly.
It is important to note that different manufacturers use different additives to improve properties. These can be fluorine-containing components to enhance the hydrophobe or metal nanoparticles for color depth. However, the basic element always remains silicon, which provides mechanical strength layer.
Before purchasing the composition, check its expiration date. Quartz coatings have a limited shelf life in a closed jar, after which they may simply not polymerize.
Differences between quartz and ceramics and liquid glass
The confusion in terms did not arise out of nowhere, since the boundaries between these concepts are often blurred in marketing. Technically, “ceramics” and “quartz” in the context of auto chemicals are often the same thing, since ceramics are also based on metal oxides. However, there are nuances in concentration and production technology.
Liquid glass (Silicate) is a simpler predecessor of modern coatings. It creates a glossy layer, but its hardness and durability are significantly inferior to quartz counterparts. Quartz is positioned as a next-generation material with improved adhesion and resistance to alkaline shampoos.
- 🧪 Base: Quartz is based on high purity SiO2, while cheap ceramics may contain less active substance.
- ⏳ Durability: High-quality quartz lasts from 1 to 3 years, while liquid glass can disappear after 6 months.
- 💧 Hydrophobic: Quartz compositions usually demonstrate a more pronounced water-repellent effect ("lotus effect").
When choosing protection, look not at the name on the label, but at the technical characteristics specified by the manufacturer. Often, under the loud name “nano-ceramics”, a conventional silicate sealant with a minimal content of solid particles is hidden.
Main functions and advantages of the coating
Why waste money and time on this procedure? The main goal is to create a barrier between the aggressive external environment and the delicate paintwork of your car. Road chemicals, bird droppings, tree sap and tar stains will all degrade clearcoat if not protected.
The quartz layer works like inert shell. Chemicals cannot immediately reach the paint, which gives you time to safely remove the stain without consequences. In addition, the hardness of the coating reduces the risk of so-called “cobwebs” (small scratches) after contact washing.
| Function | Description of the effect | Validity period |
|---|---|---|
| Hydrophobic | Water rolls into balls, carrying away dirt | Up to 3 years |
| Anti-graffiti | Easy removal of stickers and paint | Up to 2 years |
| UV protection | Preventing color fading in the sun | Whole service life |
| Easy Clean | The body gets dirty less and is easier to clean | 1-2 years |
The aesthetic aspect is also worth mentioning. Quartz adds depth and richness to the body color, turning black black and red bright scarlet. This occurs by filling the microscopic pores of the varnish with a transparent polymer, which evens out the optical properties of the surface.
Application technology: step-by-step instructions
The process of applying quartz is not simply a matter of “smear and rub.” This is a multi-stage procedure that requires strict adherence to technology. A mistake at any stage can result in the coating not sticking or showing spots that will have to be polished.
First, the car undergoes a deep wash using alkaline shampoo to remove the main layer of dirt. Then comes the stage decontamination, where with the help of special means (anti-bitumen, metal remover) stubborn contaminants that ordinary water does not remove are cleaned.
☑️ Preparing the body for quartz
The most important stage is polishing. Quartz does not hide defects, but emphasizes them. Therefore, before applying protection, the body is polished, removing scratches and holograms. Only after this, in a perfectly clean room, is the composition itself applied.
Application technique:1. Apply 2-3 drops to the applicator.
2. Grind crosswise over the element (50x50 cm).
3. Wait 3-5 minutes (time depends on temperature).
4. Rub the remains with microfiber until dry.
⚠️ Attention: When working with quartz compounds, you need to wear a respirator and gloves. Solvent vapors may be toxic and contact of concentrate with skin may cause irritation.
After application, the car requires time for initial polymerization, usually from 1 to 4 hours, depending on humidity and air temperature. Complete crystallization occurs within 7-14 days; during this period it is not recommended to wash the car with chemicals.
Service life and operating conditions
Many manufacturers promise fantastic durability of up to 5-9 years, but real practice makes its own adjustments. In the Russian climate, with its temperature changes, reagents on the roads and frequent car washes, quartz coating lives on average 1.5–2 years.
Many factors influence service life. Frequent use of aggressive brushes in self-service car washes quickly wears out the protective layer. Also affected by exposure to ultraviolet radiation and constant temperature changes, which cause microscopic expansion and contraction of the varnish along with the coating.
- 🚿 Washing frequency: The more often you wash, the faster the hydrophobe goes away, although the base may remain.
- 🅿️ Parking: Cars stored in a garage retain the coating longer than those kept outside.
- 🧴 Care: Using the right shampoos (without wax and aggressive chemicals) prolongs the life of quartz.
To extend the life of the coating, it is recommended to use special activator sprays (top-coat) once every 3-4 months, which refresh the hydrophobic properties and fill microdamages in the base layer.
The actual service life of quartz in the city is about 20-30 thousand kilometers or 1.5 years of operation, after which it requires updating or re-application.
Cost and feasibility of use
Is the game worth the candle? The financial issue is always acute. Professional application of quartz in a detailing center can cost from 15 to 50 thousand rubles and more, depending on the class of the car and the number of layers. Self-application will cost less, but requires the purchase of a polishing machine and consumables.
If you have a new car and want to preserve its salable condition for future resale, or simply love the perfect appearance, quartz is definitely worth the money. It keeps the body fresh and simplifies maintenance.
However, if the car is already 10 years old, the varnish has scuffs and faded color, then applying expensive quartz without preliminary restorative polishing does not make sense. In this case, the budget will be wasted, since all defects will be visible under the transparent layer.
The myth of self-healing
Quartz coatings do not have the property of self-healing scratches, like some polyurethane films. Claims of "healing" refer only to very minor damage that disappears with heat, but this is more a property of the varnish than the quartz itself.
Frequently asked questions (FAQ)
Can quartz be applied to an old car with worn paint?
Technically it is possible, but visually this will not improve the situation. Quartz is transparent and will highlight any imperfections. First, abrasive polishing is necessary to restore the gloss effect, and only then does it make sense to apply protection.
Will quartz save you from corrosion if there is already a chip down to the metal?
No, it won't save you. Quartz is not an anti-corrosion agent in the full sense. If there is a chip down to the metal, it needs to be painted over with a repair kit. The coating will only slow down the spread of rust around the chip, but will not stop the process completely.
How can you tell if the coating has stopped working?
The main indicator is the disappearance of the hydrophobic effect. If the water stops rolling into balls and begins to spread like a film, and the body begins to get dirty faster, it means that the upper functional layer has been depleted and requires updating.
Is quartz coating harmful to rubber seals?
The composition itself is not harmful, but if applied carelessly, it can leave white streaks on black plastic and rubber bands that are difficult to remove. Therefore, when polishing the body, the areas around the glass and plastic need to be sealed with masking tape.
Do I need to remove the old coating before applying the new one?
Yes, it is desirable. The old layer may interfere with the adhesion of the new one. Usually, before reapplying, do a light polish or use a special remover to open up the pores of the varnish.
