How shall chemical setting refractories be packaged?

Chemical setting refractories are designed to cure chemically and require a vapor-tight enclosure to maintain their integrity until they are ready to be used. Packaging them in heat-sealed plastic ensures that moisture and other external factors do not interfere with the setting process, which is crucial for achieving the desired properties and performance of the refractory material. This method also protects the refractories from contamination, which could occur if they were exposed to air or moisture prior to installation.

In contrast, other packaging methods such as cardboard boxes or metal containers do not provide the necessary vapor-tight seal that would prevent moisture ingress, making them less suitable for chemical setting refractories. Open air storage would further expose the refractories to environmental conditions, which could negatively affect their performance by allowing premature reactions or moisture absorption.
