Industrial Applications of Tetra(ethylene glycol) diacrylate
| Industry | Application | Process |
|---|---|---|
| Coatings & Inks | Acts as a reactive diluent and crosslinker to enhance coating hardness, abrasion resistance, and adhesion | Used in ultraviolet (UV) curing systems; polymerizes under UV irradiation in combination with photoinitiators |
| Adhesives | Functions as a high-crosslink-density monomer to improve bond strength and heat resistance | Incorporated into UV-curable or thermally curable adhesive formulations to form dense three-dimensional network structures |
| Photoresists & Electronic Materials | Serves as a photosensitive monomer for fabricating high-resolution microstructures | Applied in photolithographic processes for semiconductor and flat-panel display manufacturing |
| 3D Printing (Stereolithography) | Used as a resin component to enable rapid curing and high mechanical strength | Employed in SLA/DLP stereolithography 3D printing technologies; mixed with prepolymers and cured under UV light |
| Fiber & Plastic Modification | Applied for surface coating or copolymer modification to improve surface properties | Introduces acrylate groups via free-radical polymerization or grafting reactions to enhance scratch resistance |
