Stability and Storage
Phenalkamine may absorbs moisture and carbon dioxide when left in open container, which could result in increased viscosity, discoloration, reduction of reactivity, and/or crystallization of the products. This products should be kept tightly sealed in their in original container when not in use, and store in a cold, dry place. Expiry of the products is six months from the date of manufacture.
