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.

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%.


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.
