STORAGE AND HANDLING listed above. Before working with these products, it is your
Containers for Side A and Side B should be kept tightly responsibility to read and become familiar with the available
closed to prevent moisture contamination. Do not reseal if information on its hazards, proper use and handling. This
contamination is suspected. Use of a dry nitrogen blanket is extremely important and cannot be overemphasized.
for partial drums is recommended. Side B may be stored Information is available in several forms, e.g. material safety
at ambient temperatures. Storage for Side A should be data sheets and product labels. To obtain this information,
maintained between 77ºF (25ºC) and 95°F (35°C). contact yours Polycoat Products representative.
An additional note of caution is that exposure to temperatures
over 400°F (204°C) can create excessive pressure potentially
causing containers to rupture. Do not breathe aerosol or vapors
and avoid contact with skin and eyes. Exposure to vapors
of heated MDI can be dangerous. To heat product properly,
use well ventilated convection ovens or other methods that
distribute heat evenly. Avoid using drum heaters or other heat
sources that may cause excessive local heating.

SAFETY
Appropriate literature has been assembled which provides
information concerning the health and safety precautions
that must be observed when handling any of the products
