First, our products are ceramic or semi-ceramic. In addition to that side, the polymer chemistry is superior with AHC type epoxy. There are lots of types of epoxies... Bis A, BisF, Novolac, Phenolic, Polyamide, Aliphatic, Polyamines... etc... the list goes on and on...
Our LiquaTile 1184 is extremely hard... but flexible. About 10 years ago I developed coatings using AHC (Advanced Hybrid Cycloaliphatic) techology. This chemistry allows for a more thorough reaction that gives a higher cross link density. Then, by fluoromodification the the product is again enhanced although not astronomical in price like most Fluoropolymers.
Since it is devoid from low cost 100% solids liquid fillers such as nonylphenol or dibutyl phthalate, it gains flexibility from polymer chain extension rather than polymer chain termination. The low cost fillers also decrease the surface hardness. I'm too tired right now to type an extremely technical answer. However, the bottom line is that the ceramic modification, the AHC polymer system, higher quality materials, and the Fluoropolymer modification yields a coating that has extreme abrasion resistance without being brittle.
I may add to this after dinner... I've been working really hard in the yard all day...
