AZ DURAZANE polysilazanes can be applied on wood, metal, plastic, glasses, ceramics and other surfaces. With manufacturing facilities and research and technology support centers located throughout the world, we provide responsive, local support to our customers, helping them to rapidly bring advanced coating solutions to the market by the utilization of polysilazane resins.

Polysilazanes (PSZ) are polymers in which silicon and nitrogen atoms alternate to form the basic backbone. Each silicon atom is bound to two separate nitrogen atoms and each nitrogen atom to two silicon atoms, and both chains and rings of the formula [R1R2Si–NR3]n occur. R1-R3 can be hydrogen atoms or organic substituents. If all substituents R are H atoms, the polymer is designated as Perhydropolysilazane (PHPS) or Inorganic Polysilazane ([H2Si–NH]n). If hydrocarbon substituents are bound to the silicon atoms, the polymers are designated as Organopolysilazanes (OPSZ).
