You may have heard the term 9H ceramic coating floating around a lot. You may have seen it while surfing online. Or maybe an advert. Or you might just be seeing it here for the first time. But it all begs the same question, what is this ‘9H’ ceramic coating?


The term 9H comes from the scale of hardness and is a measurement of the hardness of the material. The scale is of two types, the pencil hardness scale, and the mohs hardness scale. In the pencil hardness scale, it ranges from 1H to 9H where one is ultra-soft and 9 is as strong as quartz.

But what does hardness have anything to do with ceramic coating?


9H ceramic coating is a permanent nano-ceramic coating that is highly concentrated and like all other ceramic coatings is in liquid form. It consists of silicon dioxide and uses nano-properties to fill itself into tiny cracks and holes that are invisible to us and bond with the paint to form a hard coating.

9H ceramic coating is akin to a thin layer of protection for your car’s surface. It’s also multilayered so upon applying more coats you can increase its thickness and therefore its hardness.

Take it as reinforced glass but instead, it has to be applied and dried to work.

Now we know what 9H ceramic coating is, let’s find out what are its advantages and disadvantages.


UV protection:

Ceramic coating definitely offers UV protection from harmful sun rays. It acts as a sunscreen that was made for your car and prevents your car paint from fading out, making it look brand new like factory paint.


When ceramic coating bonds with the car’s paint, it forms a hydrophobic layer that prevents staining and settling of liquids onto your car paint. It even prevents corrosivity from acidic materials and thus prevents rusting of your car surface.

Easy Maintenance:

Ceramic coating’s hydrophobic properties make it so much easier to clean and wash your car. It reduces the time you need to spend cleaning your car. Just wipe away with a microfiber cloth, and you’re done.


Doesn’t stop rock chips:

Ceramic coating can prevent rock chips on your paint surface. It just acts as a sacrificial layer to protect your paint and since it’s just bonded to your car paint, it won’t necessarily prevent abrasions and rock chips from damaging your car.

Doest prevent deep scratches:

Although ceramic coating can stop those minor scratches from damaging the car paint, deep scratches that come from minor accidents or others are almost impossible for it to handle. A better alternative would be pdf in this case.

Maintenance is still required:

Just because you’ve got on ceramic coating, doesn’t mean the car requires no maintenance. Rather, not maintaining your car can actually lead to staining and overall damage to the coating entirely.


Coatings that present themselves to be harder than 9H and ranging in values above such as 10H, 15H are a scam since the hardness of this range have no elastic properties while also being too thick, and getting it on your car can be especially damaging as it can easily manage to crack your whole coating.
