PU adhesive is made of polyurethane (polyurethane), chemically known as polyurethane ester. It is a high-molecular polymer material formed by the chemical reaction of polyols and polyisocyanates.
1. Storage Conditions: PU adhesive should be stored in a cool, dry place, avoiding direct sunlight. The recommended storage temperature is generally between 5-40°C.
2. Packaging Containers: Keep containers tightly closed to prevent solvent evaporation or moisture intrusion. Seal the packaging promptly after use.
3. Inventory Management: Follow the first-in, first-out (FIFO) principle to avoid performance changes due to long-term storage. Regularly check the condition of inventory products.
4. Safety Measures: The storage area should be well-ventilated and away from fire and heat sources. Operators must wear protective equipment.
