Storage & Handling

Recommended Storage
Store in well-ventilated place. Keep container tightly closed. Store locked up.mubychem.com
Handling Precautions
Use in ventilation or with respiratory protection — vapour is the primary exposure. Chemical splash goggles and gloves. Open and transfer cool; pressure can build in warm sealed containers. Neutralization with acid is exothermic.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities
Acids (violent neutralization), copper, brass, zinc, aluminium and their alloys, oxidizers, halogens, mercury, and many aldehydes/ketones.Class-level guidance — not product-specific; the SDS controls.
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.
