Perhydropolysilazane (PHPS) or Inorganic Polysilazane IOTA-PHPS

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

Technical Parameters:

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

Curing mechanism:

The curing of the coating material mainly is the Si-N bond hydrolysis, the mechanism is as follows:

Curing conditions:

Room temperature: more than 7 days

Moisture curing: humidity 90%, temperature 150 ℃, 2h

Coating properties:

Composition: SiOx

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)
                                   6H (Mitsubishi)

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.

Applications:

Building anti - graffiti

Metal anti-corrosion

Rail

Semiconductor insulating layer

electronic circuit

Plastic packaging waterproof gas barrier

Metal high temperature oxidation resistance

Surface hardening coating

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.

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.
