STORAGE AND HANDLING Closed Cell Content 85%
Containers for both Side-A and Side-B should be kept tightly
closed to prevent moisture contamination. Do not reseal if PROCESSING CHARACTERISTICS @ 74ºF (25ºC)
contamination is suspected. Use of a dry nitrogen blanket Ratio, by Volume A:B 1:1
for partial drums is recommended. Side-B may be stored
at ambient temperatures. Storage for Side-A should be
maintained between 77ºF (25ºC) and 95°F (35°C). For best
results, this product should not be allowed to freeze, although
it may be re-heated in a well ventilated oven for a period of information on its hazards, proper use and handling. This
time to re- liquefy solid particles. To avoid product degradation, is extremely important and cannot be overemphasized.
product temperature during re-heating should not exceed Information is available in several forms, e.g. material safety
140°F (60°C). data sheets and product labels. To obtain this information,
contact yours Polycoat Products representatives.
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.
