[Opti-Coat is not a nano particle; it is rather a pre-polymer that cross links and forms a continuous film on the surfaces it is applied to similar to a single component isocyanate that forms a clear coat finish. Opti-Coat also reacts with the substrate that it is applied to so it will not delaminate. Nano particles are sub micron particles that are created by controlled reactions or by breaking down larger particles. They do not react or form bonds. The application of Opti-Coat takes less than 10 minutes for a full size car, if it is done correctly. It applies just like Opti-Seal; however, if there is over application, you have to remove the excess within the first 10 minutes (just leveling with the applicator-CT). Otherwise, once it cures, you have to buff off the excess (machine polishing-CT). Most people apply this product to one panel at a time and check for any unevenness before moving to the next section. As far as the durability, it is similar to urethane clears. It will not wash away or break down; however, you can polish it over time! The hardness starts at 6-7 but will increase over time to 9H as it is exposed to heat.
Opti-Coat is based on a resin pre-polymer that we manufacture and once it is applied, it cross links and reacts with urethane and other clear coat paints. Opti-Coat has better chemical resistance, scratch & mar resistance, and release properties than any automotive coating in use. This coating like a regular clear coat lasts indefinitely unless it is removed by polishing, sanding, or paint removers.
The coating will get to a hardness of 9H after it is fully cured. The solvents used in Opti-Coat are also used in hand lotions and other cosmetic products. The polymers, however, are very reactive and should be used with caution and that is one of the reasons we only offer it to professional detailers] Dr. G of Optimum Polymer Technologies.
