Name: Hydrophilic Super Hard Stain Resistant Nano-Coating Materials
English synonyms: PHPS
Polysilazane Liquid Coating Materials
Description:
The coating product is mainly composed of perhydropolysilazane IOTA PHPS,diluted and stored in a solvent.
Features:
Good solubility
Short curing time
Curing a variety of ways
Good adhesion on the metal ceramic polymer materials
Can be converted to SiO2 at a lower temperature

Product packaging:
According to customer demand, 0.5-10 liters metal sealed drum, generally use xylene, dibutyl ether or dichloromethane for filling, solid content of 2-20%.
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 acetone or solvent oil to wipe the tool cleaning.
IOTA PHPS cured, the solvent can not be washed away.
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.
Acid (10% hydrochloric acid): about a month.
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.
