ROCRYL 420 Hydroxyethyl Acrylate causes severe eye and skin irritation, is a strong skin sensitizer and is highly toxic. Contact with eyes may cause blindness and with skin may be fatal.
Unless well controlled, polymerization of monomers such as ROCRYL™ 420 Hydroxyethyl Acrylate is a significant concern. In order to prevent unscheduled polymerization, hydroxyethyl acrylate must be stored and handled properly including the use of a stabilizer (inhibitor), storage under an oxygen containing atmosphere (never inert gas), at temperatures below 38°C (100°F), and used before the shelf life has expired (see MSDS). To minimize the risk of storing material beyond the shelf life, 'first in-first out principle' should be used when handling drums.
Do not store this material in containers made of carbon steel.
Local regulations must be observed for storage of materials such as polymerization of monomers such as ROCRYL™ 420 Hydroxyethyl Acrylate. Please contact your local Rohm and Haas representative for recommendations for the design of storage facilities or additional safe handling advice.
Rohm and Haas Company maintains comprehensive and up-todate Material Safety Data Sheets (MSDS) on all of its products. These MSD sheets contain pertinent information that you may need to protect your employees and customers against any known health or safety hazards associated with our products.
Under the many local, national and regional regulations, workers must have access to and understand MSDS on all hazardous substances to which they are exposed. Thus, it is important that you provide appropriate training and information to your employees and make sure they have available to them MSDS on any hazardous products in their workplace.
MSDS on non-hazardous as well as hazardous products are sent by Rohm and Haas to both the customer's “bill to” and “ship to” locations upon initial shipment (including samples) of any product. If you do not have access to one of these MSDS, please contact your local Rohm and Haas representative for an additional copy. Updated MSDS are sent, upon revision, to all customers of record. In addition, MSDS are sent on an annual basis to all customers of record.
