Storage & Handling

Recommended Storage
Cool, well-ventilated flammable-liquid storage area. Tightly sealed original containers. Segregate from oxidizers and acids. Bond and ground bulk storage.Class-level guidance — not product-specific; the SDS controls.
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 oxidizers, strong acids, isocyanates, anhydrides. Hygroscopic — protect from atmospheric moisture for water-sensitive end uses.Class-level guidance — not product-specific; the SDS controls.
Shelf Life
Consult Technical Services for product-specific shelf life
