Summary:
An introduction to the use of photoinitiators covering:
- Components of the photoinitiator "cocktail"
- Different photoinitiator mechanisms
- Different photoinitiator chemistries
- Selection criteria and factors affecting performance
Photoinitiators can be of a variety of types, split by chemistry and the mechanism by which they create radicals under the influence of UV light. They can also act in different ways in the curing of a UV-curable film. I would like to explore the performance characteristics of photoinitiators, along with some rationale used in selecting them, usually in a blend, for particular curing applications.
