Polysilazane Resins

Polysilazane resins(organopolysilazanes) are a class of polymers with backbones consisting of alternating silicon and nitrogen atoms, where silicon atoms bear organic substituents. Polysilazane resins feature excellent thermal stability and oxidation resistance, and can be converted into ceramic phases such as Si₃N₄ and SiCN at high temperatures, serving as ceramic precursors. Polysilazane resins are widely applied in ceramic coatings, fiber impregnation and composite matrixes, enabling low-temperature shaping followed by high-temperature ceramization.

MQ Silicone Resins

MQ silicone resin is a type of organosilicon polymer built from M monofunctional and Q tetrafunctional siloxane units. It features high thermal stability, excellent weather resistance and good compatibility with many silicone materials. This resin is widely used as tackifier, reinforcing filler and film-forming agent in coatings, adhesives and release liners.

Phenyl Silicone Resins

Phenyl silicone resin is a three-dimensional crosslinked organosilicon polymer with Si-O-Si backbone and phenyl groups bonded to silicon atoms. Compared with methyl silicone resin, it features superior heat resistance, radiation resistance, high refractive index and better compatibility with most organic resins. It is widely applied in high-temperature coatings, class H insulating varnishes, LED optical encapsulants and weather-resistant protective films.
