7. HANDLING AND STORAGE
Handling:
Avoid contact with eyes, skin and clothing. Avoid breathing vapor and mist. Wash thoroughly after
handling. Avoid contact with fabric or paper goods. Contact with these materials may cause rapid
polymerization which can generate smoke and strong irritating vapors, and cause thermal burns.
Storage:
Keep in a cool, well ventilated area away from heat, sparks and open flame. Keep container tightly
closed until ready for use.
Incompatible products:
No special restrictions on storage with other products.
For information on product shelf life contact Henkel Loctite Customer Service at (800) 243-4874.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering controls:
Use positive down-draft exhaust ventilation if general ventilation is insufficient to maintain vapor
concentration below established exposure limits.
Respiratory protection:
Use NIOSH approved respirator if there is potential to exceed exposure limit(s).
Skin protection:
Use nitrile gloves and aprons as necessary to prevent contact. Do not use PVC, nylon or cotton.
Eye/face protection:
Chemical splash goggles or safety glasses with side shields.
See Section 2 for exposure limits.
