Most of the time we recommend and install SiO2 based coatings from Holy Grail Ceramics. HGC has a higher active ingredient content than the competitors mentioned in the Sio2 category. Through our own testing we have also found that it performs better, lasts longer and requires less maintenance than other ceramic coatings. Organic products, such as sealants, are carbon-based and therefore wear out over time, whereas ceramic is permanent as it is inorganic.
The most common is silicon dioxide, sometimes marketed as glass, quartz or ceramic, and in all cases this is true. Paint coatings are characterised by their silicon (not silicon) content, and two main variations of silicon are used. SiC is chemically superior to SiO2 coatings and has a melting point of 2,730 °C (4,950 °F; 3,000 K) and is a 9 on the Mohs hardness scale. Unlike SiO2-based coatings, the SiC-based coating actually bonds to the paint and the SiC is formed as a chemical reaction in that process, not by having nano particles of the ceramic floating in a resin.
For maximum strength, other coatings require heat curing and multiple coats, with OCP that is not necessary. Opti-Coat Pro will maintain its gloss over time, SiO2 coatings start to lose their gloss due to oxidation and continue to lower, requiring the need to periodically add some type of resin to maintain or restore gloss and protection. SiO2 coatings obtain their maximum gloss immediately, and that gloss drops over time, Opti-Coat Pro obtains its maximum gloss once the polymerisation process is complete (approximately 7 days). Opti-Coat Pro is the only coating available that harnesses the strength of silicon carbide (sometimes referred to as ceramics, industrial diamonds and carborundum).
