"Spray Ceramic Coating" vs Real Ceramic Coating Liquid


It was a valiant effort though at explaining ceramic actives.
A full explanation is more detailed and nearly impossible to post here.

Real Ceramic Coating

“Ceramics” or better stated reactive silane/siloxane chemistry is some graduate level stuff but here are some quick facts: Silicone carbide is never used.

“Ceramic” is a descriptive first given as a layman’s explanation for silane condensation reactions. C-O-Si type bonding appears in ceramic compositions hence the reference. Polysiloxanes are used and do constitute the majority of “ceramic chemistry” as understood in the Detailing industry. These actives are not water soluble and must be supplied in solvent or emulsion form. If not properly catalyzed, reaction rates can be slow and/or require heat. The small bottles used by many suppliers come from the fact that the solvents are flammable. Anything over 3.5 ounces must ship ground.




Low molecular weight silicone makes up most of the “Quick Detailer” products. These products are low viscosity, clear, water based micro-emulsions or cloudy, water based non-reactive.


9H or 7H, references to “Quartz” or “Crystal” elude to hardness. Trouble with this reference is it’s improper terminology as well. The references are derived from the Moh’s hardness test for geologic mineral classification. It’s not applicable to reactive surface coatings but doesn’t seem to bother most selling it.


Pretty much all ceramic coatings are Polysiloxane polymer coatings with nano sized silica particles. There are differences in the exact polymer composition, solvent carriers, and powder size distribution of the ceramic particles. They really are just sealants with particles in them.

What are Polysiloxanes? (https://www.corrosionpedia.com/definition/1842/polysiloxanes)


Polysiloxanes, or polymerized siloxanes, are a polymer with a silicon-oxygen backbone. Its chemical formula is (R2SiO)n , where R is usually methylsiloxanes (CH3), although it can be H or alkyl or aryl group. Polysiloxane has shown greater resistance to the effects of UV radiation than organic polymers containing a carbon-carbon backbone. Polysiloxanes can be oils, greases, rubbers or plastics depending on molecular weight.


Polysiloxanes exhibit:

  • Superb abrasion and corrosion resistance

  • Strong chemical resistance

  • Anti-graffiti properties

  • Resilience to dirt pickup
