Storage & Handling
- Recommended Storage
- Keep containers tightly closed in a cool, dry, well-ventilated flammables area away from heat, sparks, open flame and direct sunlight. Keep in fireproof surroundings separated from strong oxidizers. Do not store above 49 °C (120 °F). Ground and bond containers when transferring.Adjudicated
- Handling Precautions
- Use chemical-resistant gloves and splash goggles. Bond and ground during transfer to prevent static accumulation. Eliminate ignition sources within vapor envelope.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizing agents (peroxides, nitric acid, perchlorates, hypochlorites); strong acids; alkali metals; acid anhydrides.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
