Name: Hydrophilic Super Hard Stain Resistant Nano-Coating Materials
English synonyms: PHPS
Polysilazane Liquid Coating Materials
The coating product is mainly composed of perhydropolysilazane IOTA PHPS, with a small amount of organic polysilazane, nano filler, curing accelerator and other functional additives, and is diluted and stored in a solvent.
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
Appearance: colorless transparent liquid
Solid content: 20%
Solvent: butyl ether
Liquid density: 1.16-1.31 g / ml
Density after curing: 1.6-2.0 g / ml
The curing of the coating material mainly is the Si-N bond hydrolysis, the mechanism is as follows:
Room temperature: more than 7 days
Moisture curing: humidity 90%, temperature 150 ℃, 2h
Coating thickness (nm): >100
Hardness (GPa): 3 (ammonia curable)
8-10 (high temperature curing)
Elastic modulus (GPa): 60 (NH3.H2O curing)
100-130 (high temperature curing)
Pencil Hardness: 9H(Chinese)
Transparency (visible light): > 90%
Adhesion (grid method): 0 level
Temperature resistance (air): 800 ℃
Rust, alkali, salt water resistance
Acid (10% hydrochloric acid): about a month.
Building anti - graffiti
Semiconductor insulating layer
Plastic packaging waterproof gas barrier
Metal high temperature oxidation resistance
Surface hardening coating
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.
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.
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.
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.
