Since releasing our Graphene Ceramic Coating™ in July of , we have received hundreds of questions and comments through social media, forum, Facebook community, emails, and chats, in regard to it and our follow-up products in our graphene line of products. Our Graphene Ceramic Coatings are an evolution of our traditional quartz (SiO2) based ceramic coating offerings. We are very proud to offer this technology - we have received a large amount of positive feedback and reviews on how our Graphene Ceramic Coating and other reduced graphene oxide infused products perform, their ease of application, and the wow-factor of the finished result on the vehicle. There are some misconceptions too, which we have done our best to address and explain in videos and articles, and through questions and answers across various platforms like social media live feeds, show event demonstrations, clinics, and so on. This write-up will serve to address the what’s, why’s, and how’s about our graphene products.
You can find more information on our web, so please take a look.
Update: Since publishing this article, we have introduced Advanced versions of our Graphene Ceramic Coating™ and Graphene Ceramic Spray Coating™. Graphene Ceramic Coating™ Advanced and Graphene Ceramic Spray Coating™ Advanced as their names imply, are further enhanced versions of our Graphene Ceramic Coating™ options, with even more durability due to being thicker formulas. Our advanced graphene coatings have 50% increased active resin content compared to their regular versions, meaning they leave a thicker layer of protection on the surface, with an even higher contact angle for water-repellency, less chance of water-spotting, and slicker feel.
Graphene Ceramic Coating™ Advanced and Graphene Ceramic Spray Coating™ Advanced are still easy to work with overall, and they follow the same application processes outlined later in this write-up; however they do require a little more effort and care in the application and removal process, so that is why we consider them advanced formulas. They can provide upwards of 9 years or 18-24 months of protection on your vehicle’s many exterior surfaces, depending on which option you choose.

Graphene Ceramic Coating Advanced
Minutes after unveiling our Graphene Ceramic Coating and Graphene Ceramic Spray Coating on social media, there were comments discrediting them: ‘You can’t make a raw graphene coating!’ ‘Why would you call it graphene and ceramic? It can’t be both.’ ‘Graphene is snake oil and has no benefit. It’s all marketing.’Since its launch, we have been as transparent as possible when explaining our Graphene Ceramic Coating. Our Graphene Ceramic Coating is not raw graphene, that quote above is correct - it cannot be raw graphene that is one atom thick and be a liquid form at the same time.
Reduced Graphene Oxide is a derivative of Graphene. From one of our chemists,Graphene - a monolayer of graphite - is able to be processed into graphene-oxide (GO), which makes thematerial vastly easier to process and formulate around.Our chemists then used this technology to allow aReduced Graphene Oxide matrix to modify the ceramic coating backbone, enhancing the performance on a surface even further by using the bonding characteristics of the ceramic coating. Our Graphene Ceramic Coatingimproves upon the characteristics of our UV Ceramic Paint Coating and UV Ceramic Wheel Coating options by offering greater hydrophobic behavior, additional resistance to chemicals, more gloss and slickness, ease of application, and more durability to scratching and marring. This is not to say though, that the coating is impervious to scratching or marring. We’ll discuss these improvements more in-depth below.
Hydrophobic Properties Modifying our ceramic coatings with the technology of reduced graphene oxide provides many benefits for our customers and their vehicles. The first improvement we mentioned above is enhanced hydrophobic behavior, which is best described as a dynamic hydrophobicity. The contact angle was marginally improved; however, the sliding angle of the coating was dramatically lowered. Contact angle in this application, is the angle at which a liquid (deionized water) meets a solid surface (coating applied to a clear coated body panel). In other words, a lower contact angle will have a wide water droplet that appears more like an oval on the surface, and a higher contact angle will have a more spherical droplet, with less of its circumference contacting the surface. Having a much lowered sliding anglemeans the degree of tilt is much less for water movement on a surface. This has a big impact on the effectiveness of a primary attribute of the coating, the self-cleaning factor. What do we mean by self-cleaning? Water, and even dirt particles to a degree, will roll off the surface more dramatically than our other coating options.
Durability
The addition of reduced graphene oxide provides more durability to the ceramic coating as well. In testing inside and outside of the lab, the reduced graphene oxide infused coating offered higher tensile strength, yielding more scratch and mar resistance. This in turn increased resistance to water spot etching and detergent washes – standing up to hundreds of traditional car washes or thousands of scrubs on an abrasion-washability tester, with little to no wear on the properly applied and cured coating. Our Graphene Ceramic Coating was also certified at a greater than 10H hardness rating by an independent testing company. What this means is that the coating withstood scratching from a pencil with a hardness rating of 10H.
Previously, 9H was the hardest grade of pencil, so when a ceramic coating is rated at a 9H hardness rating, this means that a 9H pencil does not leave a mark when firmly pressed into the surface at a 45-degree angle. Even if the graphite of the pencil breaks, if it does not leave a mark on the surface, then it is still rated at that particular hardness level. 10H pencils are now available, so we had our Graphene Ceramic Coating recertified to a 10H level. Having a higher hardness rating means that it will be slightly more resistant to etching from bird droppings or scratching from particles in a wash mitt or drying towel, which is always a good thing, but we are in no way saying that the coating is scratch-resistant - it can and will scratch or mar if subjected to sharp or abrasive forces like rocks, sand paper, and so on.
Gloss and Slickness
Both of our graphene coating offerings, Graphene Ceramic Coating and Graphene Ceramic Spray Coating, also have a more slick feel and produce a higher level of gloss to clear coated surfaces. The coating film is thicker due to a higher overall activity level in the formula when compared to our quartz (SiO2) coatings – some of our highest actives in a coating yet, other than the Pro-Level coatings offered exclusively to detailers that complete our Shine Academy educational course. Despite the higher active level, the graphene coatings don’t have as harsh of an odor as the UV Paint and UV Wheel Coating, while still being easy to apply as well, which is covered in the next section of this blog. Having said that, you still DO NOT want to smell the coatings - there is a reason they come with child-proof caps, unlike most of our other chemicals that have pleasant scents.

Applying Adam’s Graphene Ceramic Coating™ and Adam’s Graphene Ceramic Spray Coating™ are similar in application to what you’d expect from our other ceramic coatings, with a few key differences. The graphene offerings tend to flash and cure more rapidly, particularly in hot and humid climates, so they may be found to be a little less user friendly in this aspect; however most of our customers have commented that the overall application and removal process is fairly easy and forgiving when compared to some other coatings they have worked with. In environments with very low humidity though, we have found that the Graphene Ceramic Coating can flash on the surface longer than we would normally allow it, and it can still wipe away without too much effort.
Finding the sweet-spot when the coating has not flashed for too long or too little for your environment is one of the main keys for easy application. To explain this sweet-spot time frame, after you apply the coating evenly to the surface, it will begin to have an oily, rainbow-like appearance sometimes in as little as 20 or 30 seconds. This doesn’t necessarily mean that you
can remove it as soon as you see the rainbow though. You will want to wait until the coating has a slightly tacky feel to it, where your microfiber towel will have a small amount of tension as you wipe the flashed coating away. This could take 1 minute or 5 minutes or more depending on the temperature and humidity in your garage. A second way to tell when the coating has flashed and is ready for removal is when the rainbow coloration begins to fade and turn to a clear appearance. This is usually the point when the coating will have some tension when wiping it away, but again, temperature and humidity may not mean this is the case every time. On certain colors of paint, the rainbow effect can be very difficult to see as well, so ultimately it comes down to towel feel when wiping it away. Lastly, if you let the coating sit for too long though, it can become very difficult to remove, and can leave streaks, overlap lines, etc. which you will then have to fix, which we will explain below.
Multi-Surface and UV Glow
One special characteristic we found in development of the graphene coatings is they have a strong compatibility with almost any external automotive surface. Adam's Graphene Ceramic Coating™ and Adam’s Graphene Ceramic Spray Coating™ are defined as multi-surface coatings because they are appropriate for many different substrates - paint, wheels, plastic trim, chrome, glass, rubber, or metal. This provides additional ease of use since you are able to coat more surfaces on a vehicle using one coating. Our chemists were also able to incorporate our patent-pending UV Ceramic Glow Technology™ into the new graphene coatings. Just like our UV Paint, UV Wheel, and UV Leather & Interior coatings, this UV glow tracer when combined with the UV LED Light aids in the application of the coatings by providing visual confirmation of the coating film post-cure. Inspecting the UV glow ensures high spots are leveled properly and all surface areas are properly coated.
