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, Mohs topped with Booster is ultimately a stronger combo. Syncro is Mohs kitted together with a top coat called "Skin". The difference between Skin and Booster is that Skin is a flexible Si based top coat and Booster is a harder quartz based. Flexible coatings can be beneficial where large temperature fluctuations occur, a good example is leaving a black vehicle under the burning sun then showering it with cool water.
