Storage
Baydur 486 polyisocyanate must be stored in tightly closed containers and protected from contamination with moisture and foreign materials, which can adversely affect processing. It will react with water to form ureas and carbon dioxide gas, which may cause sealed containers to expand and rupture. Recommended storage temperatures are 18° to 30°C (64° to 86°F). The shelf life is six months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
