Graphene is so expensive, how is it possible to make them into coatings?
The purest form of Graphene is indeed expensive, especially when making into a one atom thick layer structure. However, we utilise reduced Graphene Oxide, which is much more economical to be functionalised and complement our coatings.
Is Artdeshine Nano Graphene Coating a one-atom thick layer of Graphene on the treated
No. Contrary to popular assumptions, our product is dominantly a silicone polymer coating
whereby reduced Graphene Oxide is suspended in the polymer matrix when cured.
How does reduced Graphene Oxide (rGO) work in a silicone polymer matrix?
While pure Graphene, in a one-atom thick layer is a very powerful material, this is still not feasible to be made for surface protection. With rGO in a polymeric matrix, the anti-corrosion
properties is very effective to fight off etching, water-spots and stains. The use of rGO with a polymer also creates a composite material that is tougher and stronger, this translates into
durability. A suitable metaphor would be how steel is made, less than 1% of carbon alloyed into iron.
Ceramic Coating VS Graphene Coating?
Both the terms “Ceramic Coating” and “Graphene Coating” are only names for identification and simple recognition. In fact, most of the coating products in the market are made from silicone polymers. Ceramic Coatings are named because of the addition of Silicone Dioxide (SiO2, the major composition of sand, glass, quartz) in a silicone polymer coating while Graphene Coatings are named due to the use of reduced Graphene Oxide (rGO). In the case of Artdeshine Nano Graphene Coating, both SiO2 and rGO are used.
Ceramic Coatings are very hard and strong, what about Artdeshine Nano Graphene Coating?
The term “Ceramic Coating” have become synonymous with a very hard and tough coating due to the fact that most manufacturers prefer to cure them into a glass-like material that is hard, transparent and reflective. However many do not know that these “Ceramic Coating” can also be cured into softer more flexible materials. For ease of identification’s sake, many prefer to associate hard and tough coatings as “Ceramic Coating”. Artdeshine Nano Graphene Coating cures into a softer and more flexible material due to the type of silicone polymers and curing agents used.
Artdeshine Nano Graphene Coating is soft so it is not scratch resistant?
To simply put it, soft or hard, brittle or flexible, thin or thick, a coating’s ability to resist abrasion and scratches is not dependent on the hardness, toughness or thickness. Any product applied by hand to a surface is too thin to exhibit any real scratch resistance (9H rated coatings or otherwise). The real reason why a treated surface is able to reduce chances of scratching is due to the lack of friction, or sleekness.
What is 9H Scratch Resistance or MOHS Hardness Scale?
9H is the grade of pencil tip used to scratch a surface to measure abrasion resistance while hardness is measured using the MOHS Scale. Some brands or manufacturers use the words “9H Hardness” that carries no meaning.
While many coatings are made with materials that resist a 9H abrasion test or are made to be hard like glass/quartz rated 5-7 on the MOH Scale, Artdeshine Nano Graphene Coating as a cured material is only able to resist up to 7H scratch test.
Will reduced Graphene Oxide (rGO) in coatings increase the hydrophobic properties?
No. rGO used in our products is not functionalised to exhibit that property.
Will reduced Graphene Oxide (rGO) in coatings increase the hardness or abrasion resistance?
No. The hardness comes from the silicone polymer material while abrasion resistance comes
from the lack of friction due to the sleekness our products exhibits.
Will reduced Graphene Oxide (rGO) in coatings increase sleekness?
No. Sleekness is made possible from using a variant of Polydimethylsiloxane (PDMS), a type
of silicone polymer.
Will reduced Graphene Oxide (rGO) in coatings increase reflectivity/gloss?
No. These properties are entirely dependent on the polymers used. In “Ceramic Coatings”
that are cured to be hard and transparent, these usually look like optically transparent glass,
which gives reflectivity (shine) and gloss.
Coatings (Artdeshine Nano Graphene Coating) that are cured to be softer are usually slightly cloudy though when applied onto a surface is still optically clear, these will darken and
saturate (vibrant) colours.
