3. Champ d'application et utilisation
DPM is widely used as a solvent in coatings, dyes, inks, and cleaning agents. It is also a common component in brake fluids and is used in the formulation of cosmetics and personal care products due to its low toxicity and excellent solubility. In the electronics industry, DPM serves as a solvent or intermediate in the production of specialty chemicals. Its ability to dissolve a wide range of resins, including cellulose, polyvinyl acetate, and phenolic resins, makes it valuable in industrial formulations.
4. Emballage et stockage
DPM is typically packed in 195 kg steel drums, or in Bacs IBC for bulk quantities. It should be stored in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and ignition points. Containers must be tightly sealed to prevent moisture absorption and contamination. During handling, avoid contact with skin and eyes, and use appropriate personal protective equipment. Storage areas should be equipped with firefighting facilities, and DPM should be kept away from strong oxidizing agents
