Perhydropolysilazane PHPS is an inorganic polymer composed of repeating Si-N units and containing no organic groups. It can be used as a ceramic precursor to crack Si3N4 ceramics under milder conditions. Its more common use is as a coating material
Used in automotive, electronics, semiconductor, packaging, construction and other fields.
Use: As a Si3N4 ceramic precursor polymer, PHPS curing requires curing in an inert atmosphere, curing temperature 180-220 ℃, curing time 6-18 h.
As the coating material PHPS, its curing can choose constant temperature and humidity, high temperature, ammonia, infrared and other methods. The specific process parameters are adjusted appropriately according to the base material and the purpose of use.
Cleaning: After use, quickly wipe the tool with acetone or solvent oil. Once the PHPS is cured, the solvent cannot be washed away.
Operation notes:
The use of polysilazane must be in a ventilated and dry environment, and the necessary protective measures, such as gloves, masks, and protective glasses must be adopted; uncured PHPS must not be close to fire, humid air, or water.
Storage: The unopened polysilazane PHPS has a shelf life of one year; the open period of the polysilazane PHPS after opening is affected by the protection measures. Under the condition of low temperature and dry seal, the application period is more than 6 months.
Incompatible materials: Perhydropolysilazane PHPS is soluble in various polar or non-polar dry solvents. However, PHPS is sensitive to water and alcohol solvents, and undergoes hydrolysis or alcoholysis reactions, causing the product to deteriorate.
Avoid contact with protic substances such as acids and alkalis.
