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:

Store at low temperatures below 10 ℃.  

Unopened IOTA PHPS, shelf life: 1 year within China, 6 months abroad.

After opening, use up IOTA PHPS as soon as possible according to the actual situation. 

Precautions:

Should l be in a ventilated, dry environment, and the use of necessary protective measures, such as gloves, masks, goggles;

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.
