Applications

Solvent and cleaning agent; degreasing; electronics cleaning; formulation ingredient.Adjudicated

Restrictions on Use: For industrial, professional and laboratory use. Not for ingestion, medicinal or food use.

Storage & Handling

Recommended Storage
Store in tightly closed original containers in a cool, dry, well-ventilated flammable-liquids area that meets NFPA 30, away from heat, sparks and open flame. Ground and bond containers and equipment when transferring: vapor can be ignited by static discharge. Do not store with oxidizing agents, strong acids, peroxides, aldehydes, halogens, ammonia, acid anhydrides or alkali metals.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; strong acids and acid anhydrides; peroxides; aldehydes; halogens; ammonia and amines; alkali metals, potassium and aluminum; iron salts. May attack some plastics and rubber.Adjudicated
Shelf Life
Consult Technical Services for product-specific shelf life

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
