04 · Handling and storage

Storing and handling Crimidine

Storage conditions

Castrix must be stored to avoid contact with strong acids (such as hydrochloric, sulfuric and nitric) and acid fumes since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area.

Reactivity

CRIMIDINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
