Gyeon offers a range of premium quality products, which have been thoroughly tested to satisfy the needs of car detailing enthusiasts, as well as the exacting requirements of professionals. Gyeon's lineup is based on silicon dioxide (SiO2), as it's the most sophisticated car protection tech developed to date. The crucial properties of the quartz coating are its ability to increase the overall hardness of the paint up to the level of 9H (hardness of the coating determined by pencil hardness scale), as well as its measurable thickness, reaching up to 1 micron. However, the most critical property is the structural integrity displayed by the layer, meaning the mixed resins in the formulation also play a crucial part in ensuring the coating self-levels and locks onto the surface as intended.
As opposed to the majority of coatings present on the market, Gyeon Mohs ("Mohs" is from the "Mohs' scale" that determines the hardness of minerals from the German scientist Friedrich Mohs. Note: Mohs scale of SiO2 is 7, the scale used by Gyeon of 9 is the Graphite/Pencil Scale.) demonstrates the lowest shrinkability parameters. Where as most coatings shrink from 0.03 up to 0.2 microns ("shrink" means when the coating is applied, the solvent will evaporate leaving resins and SiO2 behind; the lower the SiO2 concentration the more it'll "shrink" after it's fully cured). Mohs does not shrink exceed 5% of its intended thickness - while Mohs' thickness of 0.2 microns as registered just after application, only drops to 0.19 when fully cured.
Gyeon's coating offerings can be a little overwhelming, here's a simple breakdown: CanCoat > One > Prime/Pure > Mohs > Syncro.
Pure and Mohs are the same price, are they the same? Which should I choose? Pure is designed as a single layer coating (layering is also possible), it goes on slightly thicker than Mohs, but easier to remove. Whereas Mohs requires at least 2 layers (max 3), also easy to apply and remove. Durability, gloss and hydrophobicity for both are very on par, Pure is slightly more slick but Mohs can be more durable (base Mohs chemistry is also used in the certified Mohs+ regiment), however the above can be altered by layering Booster (Gyeon's most hydrophobic consumer level top coat).
What is Gyeon Syncro? Is it the same as Mohs with Booster? No. Booster is a Fluorine (with slight Silica blend) based top coat vs the Skin's Silica based. Booster chemically reacts with the base coat, completely adheres, or becomes a part of rather, to what's underneath, becoming a SiO2/Fluorine "blend" coat, as it borrow's the base coat's hardness, thus in theory making it a more durable product. Because of the above, Booster can only be applied to "fresh" coatings, where it hasn't fully cured yet, as it won't react proper to fully cured coatings. Whereas Skin is a physical layer that sits on top of the base coat. Booster doesn't really increase the hardness much but adds additional self cleaning and hydrophobic effect. This can be felt by hand, the surface will feel much slicker (to both Skin and Booster). Application differs between the two also; Booster will evaporate very quickly, it won't leave a haze or a residue behind, where Skin will leave residue that can be buffed off easily.
