Storage & Handling
Recommended Storage
Keep tightly closed (hygroscopic) in a cool, dry place away from oxidizers. Store separately from food and drink.Adjudicated
Handling Precautions
Chemical-resistant gloves and splash goggles. Ethylene glycol grades are toxic by ingestion and must be kept away from food, drink and animals; propylene glycol grades are not. Avoid contact with hot surfaces and hot process equipment. Inhibitor packages deplete in service — monitor rather than top up blindly.Class-level guidance — not product-specific; the SDS controls.
Incompatibilities
Strong oxidizing agents, strong acids and bases, aldehydes, alkali and alkaline-earth metals, aluminum compounds.Adjudicated
Shelf Life
Consult Technical Services for product-specific shelf life
