Application Features: Highly efficient free-radical photoinitiator (99% purity) with broad absorption spectrum. Ideal for UV curing of thick and pigmented coatings. Leaves minimal residue post-cure; complies with migration standards for food-packaging inks.

Application Features: Low-cost, general-purpose photoinitiator; excellent compatibility with acrylate monomers; fast initiation; ideal for UV coatings and high-speed printing inks; 99% purity minimizes yellowing.

Application Features: Chlorine substitution enhances photosensitivity and deep-cure performance; ideal for opaque substrates (e.g., UV-curable adhesives).

Application Features: Dual-function molecule: acts as photoinitiator and UV absorber. Post-cure coatings exhibit enhanced weatherability; particularly suited for outdoor plastics and automotive topcoats.

Application Features: Symmetric structure enhances thermal stability; suitable for high-temperature pre-mixed UV formulations (e.g., 3D printing resins); low shrinkage ensures high dimensional accuracy.

Application Features: Methoxy electron-donating effect redshifts absorption; compatible with LED-UV sources (385 nm); energy-efficient; ideal for precision electronic component encapsulation.

Application Features: Low-odor, low-migration photoinitiator compliant with stringent requirements for food-contact UV inks and coatings on children’s products.

Application Features: Ortho-substituted photoinitiator with minimal steric hindrance; higher reactivity than para-isomer; ideal for rapid curing in high crosslink density formulations (e.g., dental filling resins).

Application Features: Most cost-effective UV photoinitiator with excellent synergy alongside amine co-initiators. Widely applied in standard UV inks and packaging coatings.

Application Features: Polymethyl substitution improves solubility; excellent compatibility with hydrophobic resins (e.g., epoxy acrylates); yields smooth, defect-free cured films—ideal for premium furniture coatings.

Application Features: Asymmetric structure reduces crystallization tendency; ideal for low-temperature storage and winter outdoor UV floor coatings.

Application Features: Dimethoxy structure enhances electron transfer efficiency; compatible with cationic photoinitiators for dual-cure systems; suitable for thick films (>500 μm).
