Description

ω-(Dimethylamino)-4'-Methoxy-ω-(p-Methoxyphenyl)-γ,γ-Dimethylvalerophenone CAS NO 3215-84-7 is a specialized photoinitiator compound, a key component in advanced photopolymerization systems. Its value lies in its ability to efficiently generate free radicals upon exposure to specific light wavelengths, initiating rapid and controlled polymerization reactions. This makes it an essential material for manufacturers in the UV-curable coatings, inks, and adhesives industries, where precise curing and high-performance finishes are required.

Application

• Primary photoinitiator in UV-curable coatings for wood, plastic, and metal substrates.
• Critical component in photopolymer printing plates and flexographic inks.
• Used in the formulation of UV-curable adhesives and sealants for electronics and medical devices.
• Enables rapid curing in dental restorative materials and composites.
• Facilitates production of optical fibers and other light-cured polymer components.
• Employed in 3D printing (stereolithography) resins for high-resolution prototyping.
• Acts as a radical source in specialized organic synthesis and polymer research.

Quality Control

Our ω-(Dimethylamino)-4'-Methoxy-ω-(p-Methoxyphenyl)-γ,γ-Dimethylvalerophenone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for photopolymer applications. Certificates of Analysis (COA) with full traceability are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect performance. Keep away from heat sources and incompatible materials.
