Is polyurethane adhesive a dangerous good? What should be noted when using it?
2025,12,04
Whether polyurethane adhesives are classified as dangerous goods depends on their specific components. Most common one-component polyurethane adhesives do not fall under the strict category of hazardous chemicals, but some two-component products (containing free cyanate ester monomers) or solvent-based products may be classified as dangerous goods, featuring flammability and harmfulness.
When using polyurethane adhesives, the following safety precautions must be noted:
1. Ventilation protection: Operate in a well-ventilated environment to avoid inhaling volatile gases. It is recommended to use local exhaust equipment or wear qualified gas masks in confined Spaces.
2. Contact protection: Chemical-resistant gloves, goggles and protective clothing must be worn during operation to prevent direct contact between skin and eyes. In case of accidental contact, rinse immediately with plenty of water and seek medical attention if necessary.
3. Fire and explosion prevention: Keep away from open flames, heat sources and equipment that may produce sparks. Solvent-based products are especially flammable. Smoking is prohibited in the storage and usage areas.
4. Proper storage: The product should be stored in a sealed container in a cool and dry place, away from direct sunlight and isolated from other chemicals. Two-component adhesives must be accurately mixed in accordance with the proportion specified in the instructions and used up within the applicable period.
5. Waste disposal: Uncured adhesives and contaminants should be treated as chemical waste and must not be discarded at will or poured into the sewer.
