Direct impact of metal shavings in the layer car paints Xeralik provides that deep, mirror effect that cannot be achieved using standard aluminum pigments. The technology used to produce these particles is based on mica coated with a metal oxide, which creates a multifaceted reflection of light from different viewing angles. Owners of premium car brands often choose this type of coating, as it gives the body volume and richness that is inaccessible to ordinary metallic paints.
The process of polymerization and drying of this material requires strict adherence to the temperature regime, otherwise the orientation of the flakes (scales) in the layer may be disrupted. Xirallic is a trade name that has become a household name for a whole class of high-performance pigments produced by Eckart. When making local repairs or completely repainting the body, the master must take into account the high hiding power and specific viscosity of the material to achieve an ideal result.
⚠️ Attention: Applying paint with the Xeralic effect requires a high-class spray gun and experience working with complex pigments, otherwise clouds and uneven distribution of particles may form.
Technological features of Xirallic pigmenth2>
The basis of this type of coating is synthetic mica particles, which are coated with a thin layer of metal oxide during the production process. Unlike traditional aluminum, which simply reflects light, Xeralic pigment refracts it, creating the effect of depth. The particles have a strictly defined geometry and size, which allows them to be placed in the paint layer parallel to the surface of the body after the solvent evaporates.
To achieve maximum visual effect, the correct viscosity of the material during application is critical. If there is too much solvent, the particles may sink into the layer or turn over, resulting in loss of gloss. Modern tinting systems make it possible to achieve thousands of shades using a base with this pigment, but the base color of the substrate also plays a role in the final perception of color by the human eye.
- ✨ High degree of light reflection due to the flat geometry of mica particles.
- 🎨 Ability to create complex color transitions (flip-flop effect).
- 🛡️ Resistance to ultraviolet radiation and aggressive chemical environments.
Chemical composition of the coating
It is based on synthetic mica particles (fluorphlogopite) coated with titanium dioxide or iron oxide. The thickness of the coating on one particle is only a few nanometers, which creates light interference.
Surface preparation and priming
The quality of the final coating depends 80% on the preparation of the metal base for automotive enamel. The surface must be perfectly flat, grease-free and dry. Any imperfections remaining under the clearcoat or basecoat will be visible, especially on darker Xeralic tones.
The process begins with mechanical treatment and the use of acid or epoxy primers. It is important to ensure adhesion of all subsequent layers. If local repairs are being carried out, the boundaries of the transition of the old varnish must be carefully matted. Usage adhesion_promoters (adhesion enhancers) are often recommended by manufacturers of paints and varnishes for complex plastic elements.

Application process and drying
The technique of applying a base with the Xeralic effect differs from working with regular metallic. The pressure in the spray gun is usually set in the range of 2.5-3.0 atmospheres, and the torch should be wide. The first layer is applied thin, almost dry, to set the base, but not completely cover the surface.
The second and subsequent layers are applied with a flash-off time, which is usually 10-15 minutes at a temperature of 20°C. It is critical not to overdry the base before applying varnish., as this may lead to poor adhesion of the varnish layer or clouding. The number of layers varies from 2 to 4 depending on the coverage of a particular shade.
| Parameter | Meaning/Recommendation | Note |
|---|---|---|
| Outlet pressure | 2.5 - 3.0 atm | Depends on viscosity |
| Nozzle diameter | 1.3 - 1.4 mm | For water-soluble bases |
| Interlayer drying | 10-15 min | At 20°C |
| Drying temperature | 60°C | Forced drying mode |
Varnishing and polishing
After the color layer with pigment has dried Xirallic Protective varnish must be applied. It is the varnish that gives the final gloss and protects the soft base layer from external influences. For premium cars, ceramic varnishes or varnishes with increased hardness are often used.
Polishing is carried out only after complete polymerization of the varnish, which can take from 24 hours to several weeks depending on the type of hardener. The use of abrasive pastes allows you to remove shagreen ("orange peel") and achieve a mirror shine. However, with effect bases you need to be careful not to rub off the color of the polish.
⚠️ Attention: When polishing transition zones (blend-in), use minimal pressure so as not to disturb the orientation of Xeralic particles in the base layer.
Compatibility and tinting
Tinting systems from leading manufacturers (PPG, BASF, Mobihel, Duxone) have special formulas for working with these pigments. It is important to use original binders and solvents recommended by the pigment manufacturer. Mixing products from different brands may result in a chemical reaction, swelling or discolouration.
When choosing a color for an old car, computer tinting is often required, taking into account the fading of the old coating. Xeralic paint has the property of changing shade depending on the viewing angle, so visual inspection of samples under different lighting conditions is mandatory. Computer selection provides only a basic formula, which the master must bring to the ideal “in color”.
Helpful Hint: Always do a test paint (spray-out) on a metal plate and dry it under the same conditions as the car part to see the actual effect.
Cost and economic feasibility
The price for materials with the Xeralic effect is significantly higher than for standard metallics. This is due to the complexity of producing the pigment itself and the high requirements for painting conditions. However, the visual effect completely justifies the cost, especially for business class cars and above.
The cost of the work should also include higher material consumption, since more layers may be required to cover and create color depth. In addition, working with such materials requires a highly qualified painter, which also affects the final price of the service.
Main conclusion: The use of Xirallic pigment is an investment in the exclusive appearance of the car, requiring professional application and high-quality accompanying materials.
Frequently asked questions (FAQ)
Is it possible to apply Xeralic paint over regular metallic?
Technically, this is only possible if the old coating is completely removed down to the ground. Applying a new base over an old one without proper preparation will result in peeling. If the old layer is intact, it needs to be matted and degreased, but it is better to use compatible products of the same system.
How long does Xirallic effect paint dry before varnishing?
Interlayer drying time is usually 10-15 minutes at a temperature of 20 degrees Celsius. Before applying the varnish, the base should become matte and stop sticking, but should not dry completely (overdry), otherwise the adhesion of the varnish will be impaired.
What is the main difference between Xeralic and regular aluminum?
Regular aluminum pigment is irregularly shaped and simply reflects light like a mirror. Xeralic particles have a perfect flat shape and refract light, creating the effect of depth and changing shade depending on the viewing angle (flip-flop).
Do I need a special varnish for Xeralic paint?
A special varnish is not necessary, but it is recommended to use high-quality, two-component, high solids varnishes. This will maximize the depth of color and ensure the durability of the coating.
