Abstract: Silicone ceramic coatings made through sol-gel technique show unparalleled comprehensive advantages over traditional organic coatings, such as high hardness, excellent weathering resistance, flame retardant, safe and nontoxic. They have been widely used in non-stick pan, aluminum curtain wall, subway locomotive. Herein, the relationship between the preparation processes, formula and the performance of ceramic coatings was reviewed. Common misconceptions in the formulation design were also discussed. Furthermore, two kinds of novel silicone ceramic coatings including flexible silicone ceramic coating and plastic silicone ceramic coating were introduced. Further trend was forecasted as well.
