How to use:
First, clean the substrate surface, coating products using spin-coating, rubbing, spraying, dipping, etc. construction, and then by room temperature curing, high temperature curing, etc. curing.
Clean:
Proper cleaning is important. After using promptly use aceton or solvent oil to wipe the tool cleaning.IOTA PHPS cured, the solvent can not be washed away.
Product packaging:
According to customer demand, 0.5-10 liters metal sealed drum, generally use xylene, dibutyle ether or dichloromethan for filling, solid content of 2-20%.
Storage:
Shelf life: 2years; after the application, it depend on the protective measures, sealed low temperature drying case, the applicable period of more than half a year.
Precautions:
Should l be in a ventilated, dry environment, and the use of necessary protective measures, such as gloves, masks, goggles; shall not
Do not place uncured IOTA PHPS near to fire, humid air, or water.
After opening, seal it in a timely manner. If it is used in a humid environment, replace the container with nitrogen after using.
Q: What is polysilazane?
A: Polysilazane is a high molecular polymer formed by connecting silicon and nitrogen elements through silicon-nitrogen bonds. It usually has very stable chemical properties.
Q: What are the characteristics of polysilazane?
A: Polysilazane generally has excellent high temperature resistance, fire resistance and electrical insulation properties. It also exhibits good chemical stability and corrosion resistance.
Q: What are the application fields of polysilazane?
A: Polysilazane is commonly used in coatings, refractory sealing materials, electrical insulation materials, aerospace and some chemical industries in special high-temperature environments.
Q: How are polysilazane different from organic polymers?
A: Polysilazane has higher temperature resistance and chemical stability than organic polymers, such as plastics or rubbers, but may have slightly different properties in other aspects.
Q: What is the preparation method of polysilazane?
A: The preparation of polysilazane usually involves the reaction of silicon source and nitrogen source, forming silicon-nitrogen bonds under specific conditions, and obtaining polymer materials through specific processes.
Q: How stable is polysilazane at high temperatures?
A: Polysilazane usually has good stability in high temperature environments, can maintain its structure and performance, and can withstand a certain degree of high temperature.
