4. Storage
PURANOL RF4111K is slightly hygroscopic and must be stored properly so that contamination with water and absorption of atmospheric moisture is prevented. Open drums should be closed tightly to avoid contact with moisture and loss of blowing agent. Drums should be kept cool as high temperature causes loss of blowing agent and increased reactivity. Storage temperatures below 25°C are recommended.
