Storage
Storage of the components(resin or curing agents etc.) at 6-35℃ in tightly sealed and dry. Under these conditions, the shelf life will correspond to the expiration date(2 years). After this date, the product may be processed only following re-analysis. Partial emptied containers should be closed tightly immediately after use.
Packing
Epoxy resin 20kg/pail or 220kg/pail
Curing agent 20kg/pail or 220kg/pail
First Aid
Emergency treatment for eye contact: If the eyes are accidentally contaminated with resin, curing agent or castable, they should be immediately rinsed with clean running water for 15-20 minutes, and then seek medical attention immediately. Avoid rubbing the eyes or using eye drops without doctor's guidance.
Treatment for skin contact:
First wipe the contaminant with a clean soft cloth, avoid rubbing hard
Rinse with plenty of running water for at least 15 minutes
If persistent pain/redness/blisters occur, seek medical attention immediately
Other precautions:
Contaminated clothing should be sealed immediately
Move to a ventilated place if uncomfortable after inhaling steam
It is recommended to keep the chemical packaging for doctor's reference
All contact situations require subsequent medical evaluation
