NINGBO INNO PHARMCHEM CO.,LTD. serves as a vital resource for industries leveraging UV curing technology, a process that relies heavily on the functionality of photoinitiators. These specialized chemicals are the linchpin of UV curing, initiating rapid polymerization reactions that transform liquid coatings, inks, and adhesives into durable solid materials.

The diverse range of photoinitiators can be broadly categorized based on their initiating mechanism: free radical photoinitiators and cationic photoinitiators. Free radical photoinitiators, such as alpha-hydroxy ketones and acylphosphine oxides, are widely used for curing acrylate-based formulations. They generate free radicals upon UV exposure, which then propagate a chain reaction. Cationic photoinitiators, often based on onium salts like iodonium or sulfonium salts, are used for curing epoxy, vinyl ether, and oxetane systems. They generate strong acids that initiate cationic polymerization.

The choice of photoinitiator is crucial for achieving desired curing performance and final product properties. Factors influencing this selection include the type of resin system being cured, the wavelength of the UV light source, the required cure speed, the desired film thickness, and potential issues like oxygen inhibition or yellowing. For instance, formulations for clear coatings or sensitive substrates may require photoinitiators that generate minimal color or are highly efficient at lower concentrations. When businesses aim to buy photoinitiator chemical, consulting with a knowledgeable supplier like NINGBO INNO PHARMCHEM CO.,LTD. can provide invaluable guidance.
