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.

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.
