Applications of 142770-42-1
| Industry | Application | Process |
|---|---|---|
| UV-Curable Coatings | Photoinitiator for UV-curing systems | Acts as a Type I free-radical photoinitiator; undergoes homolytic cleavage under UV irradiation to generate free radicals that initiate polymerization of acrylate monomers |
| UV-Curable Inks | Photoinitiator to enhance cure speed and surface hardness | Incorporated into offset, flexographic, and inkjet ink formulations; enables rapid crosslinking upon irradiation with 365 nm UV light |
| UV-Curable Adhesives | Photoinitiating component to improve initial tack and through-cure performance | Used in combination with other photoinitiators (e.g., TPO) to increase resistance to oxygen inhibition and improve curing efficiency in thick films |
