Application

1. UV coatings and inks, as key monomers, are used in UV curing coatings and inks in furniture, automobiles, electronic equipment and other fields, providing fast curing, high gloss and wear resistance.

2. Photoresists and 3D printing resins, as photosensitive components in semiconductor lithography processes, are also used in stereolithography (SLA) 3D printing resins to ensure high precision and mechanical strength.

3. Adhesives, used for UV curing glue, suitable for bonding glass and plastics, with low shrinkage and high bonding strength.

4. Polymer material modification, used as a cross-linking agent: introducing a cross-linking structure into polymers (such as rubber and plastics) to improve heat resistance, solvent resistance and mechanical strength, used as a reactive diluent: reducing the viscosity of the resin system (such as epoxy or polyurethane systems), participating in the curing reaction, and reducing volatile organic compounds (VOC).

5. Packaging and insulation materials: used for LED packaging and circuit board protective coatings, providing high temperature resistance and electrical insulation properties.

6. Flexible electronic devices: as a component of a flexible substrate, it adapts to the flexibility requirements of bendable displays or wearable devices.

7. Optical materials: used for transparent plastics and optical fiber coatings, taking advantage of their high light transmittance and low yellowing properties.

8. Composite materials: used as resin matrix to reinforce carbon fiber/glass fiber composites to optimize toughness and fatigue resistance.

9. Dental materials: used for light-cured composite resins to repair teeth, ensuring rapid prototyping and biocompatibility.

10. Medical device coatings: used as antibacterial or waterproof coatings, applied to the surface of catheters and surgical tools
