Storage & Handling

Handling

SIROPOL­ 8341 resin  contains  ingredients,  which could  be harmful  if  mishandled.  Contact with skin and eyes should be avoided and necessary protective equipment  and clothing should be worn.

Saudi Industrial Resins Ltd., maintains Material Safety Data Sheets on all of its products.  Material  Safety  Data Sheets  contain health and safety  information for your development  of appropriate product handling procedures to protect your employees and customers.

Our  MSDS should  be read and understood by all of your supervisory  personnel  and employees  before using SIR`s products in your facilities.

Recommended Storage

DRUMS:­ Store at temperatures below 25 o C.  Storage life decreases with increasing storage temperature.  Avoid exposure to heat sources, such as direct sunlight or steam pipes. Keep containers sealed to prevent moisture pickup and monomer loss.  Rotate stock.

BULK: ­ Store in stainless steel tanks or tanks lined with epoxy or phenolic coatings.  Observe precautions against heat and moisture (see above).  An oxygen or dry air spurge may be desirable  to keep inhibitors activated. Store at temperature below 25 ºC.
