| Storage | HMDI is sensitive to moisture and therefore should be stored in its sealed original containers. Water or moisture in the air reacts with the product and generates pressure. If partially filled containers are stored, it is advisable to blanket the liquid surface with dry nitrogen before sealing. At approx. 25 ℃, crystals will generate in HMDI and set on the bottom. The product should therefore be heated to 40 ~ 50 ℃ and homogenized before use. This process also allows the use of the product which has already crystallized. |
