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.
