Product packaging:

According to customer demand, 0.5-10 liters metal sealed drum, generally use xylene, dibutyl ethe r or dichloromethan e 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 aceton e 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 OPSZ-9150 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.
