First, the principle
Silicone resin coating is based on silicone resin as the main film-forming substance. Through chemical reaction or physical mixing, the silicone resin is combined with other functional materials to form a coating with specific properties.The principle is based on the unique molecular structure of silicone resin：
Molecular structure: The main chain of silicone resin is composed of silicon-oxygen bonds (Si-O), which have high bond energy and strong stability, giving the coating excellent heat resistance, weather resistance and chemical stability.
Functional group function: The organic groups of the molecular side chain (such as methyl, phenyl, etc.) can adjust the flexibility, adhesion and compatibility of the coating with other materials.
Crosslinking curing: Through heating or catalyst action, the active groups (such as hydroxyl groups and alkoxys) in the silicone resin condense to form a three-dimensional mesh structure, which improves the mechanical strength and durability of the coating.
Second, the application
Silicone resin coating is widely used in many fields because of its excellent performance：
Aerospace field
