Key Packaging & Storage Considerations
Material Compatibility: DTPMPA is an acidic liquid and should be stored in plastic (HDPE) drums or IBC containers. Avoid contact with metals to prevent corrosion .
Storage Conditions: Store in a cool, dry, well-ventilated area, away from direct sunlight and heat sources. Keep containers tightly closed and away from incompatible materials such as strong oxidizers .
Shelf Life: Typically 10 to 12 months under appropriate storage conditions .
Transport Classification: DTPMPA is classified as a corrosive liquid (UN3265, Class 8) for transport purposes .
