| 主要用途 | Used as a chemical intermediate and adhesive. It is employed in the synthesis of light-cured coatings, crosslinking resins, and other materials. It can also copolymerize with acrylic esters to produce polymers with weather resistance and chemical resistance, commonly used in coatings, adhesives, and sealants. |
| Polymerization | Capable of spontaneous polymerization through vinyl groups, and radical initiation can form soluble cyclic polymers. Inhibitors such as 2.6-di-tert-butyl-4-methylphenol can be used. |
| Safety Hazards | Harmful if inhaled. Causes skin irritation and serious eye damage. May cause respiratory tract irritation. Keep away from heat, sparks, and open flames. Wear appropriate protective equipment when handling. Avoid contact with strong oxidants and strong bases. |
| Storage Conditions | Store in a cool, dry, and well-ventilated place. Keep container tightly closed and store at 2-8°C. |
