THE FACTS... The Differences Between SiC-Based Ceramic Coatings (OPTI-COAT) And Other Si-Based Ceramic Coatings02

-The differences and similarities between the ceramic coatings available on the market are quite impressive

All true coatings are ceramic based, ceramic being a term meaning inorganic. Organics like sealants are carbon based and as such wear out over time, the ceramic itself is permanent, being inorganic.

Ceramic coatings are characterized by their silicon content and 2 main variations of silicon are used. The most common is silicon dioxide (SiO2), sometimes marketed as Glass, Quartz or Ceramic and in all cases this is true. SiO2 is suspended in a resin in the form of Silicon Dioxide Nanoparticles, and the resins suspend it in a film on top of the paint. SiO2 has a melting point of 1,600 °C and is 7 on the Mohs hardness scale.

The other ceramic coating system is silicon carbide (SiC), the Opti-Coat Pro range is the ONLY ceramic coating range available that takes advantage of the strengths of silicon carbide (sometimes referred to as ceramic, industrial diamonds and carborundum) . Unlike SiO2-based ceramic coatings, SiC-based coating actually melts and mixes with the paint and the SiC is formed as a chemical reaction in this process, not by having ceramic nanoparticles floating in a resin. SiC is chemically superior to SiO2 coatings and has a melting point of 2,730 °C and on the Mohs hardness scale it is 9 .

Opti-Coat Pro is unique in many ways because of this fundamental difference in chemistry. Opti-Coat-Pro becomes one with the paint instead of suspending nanoparticles of a harder substance in a resin. This gives Opti-Coat Pro much superior chemical resistance, as the chemical must break down SiC and not break down a resin containing SiO2 nanoparticles. Opti-Coat Pro is harder than other coatings, but no coating is scratch-proof. For maximum strength, other coatings require heat curing and multiple coats, with Opti-Coat Pro this is not necessary.

SiO2 coatings achieve their maximum shine immediately and this shine decreases over time, Opti-Coat Pro achieves its maximum shine once the polymerization process is complete (approximately 7 to 30 days). Opti-Coat Pro will maintain its shine over time, SiO2 coatings begin to lose their shine due to oxidation and continue to fall off, making it necessary to periodically add some type of resin to maintain or restore shine and protection.
