Principles for use of photoinitiators

1. Photoinitiator and amine promoter EDAB are used together.
2, small smell, no poison, no environmental pollution.
3, cheap and easy to obtain, low cost.
4. Select photoinitiator with appropriate activity according to the type of prepolymer and monomer.
5, with good solubility and reactivity, less dosage, high initiation efficiency.
6, there should be a certain thermal stability, not decomposed below 85℃, there should be a long time storage stability.
7, it is best to use several photoinitiator compound, in different wavelength range can lead to curing, curing faster than a single photoinitiator.
The above content is an overview of photoinitiator, action mechanism, performance requirements, common types, characteristics and principles of use. Photoinitiator is one of the indispensable components of the free radical UV photocuring reaction system. The type and dosage of photoinitiator have great influence on the photocuring behavior of the system, and play a decisive role in the sensitivity of the photocuring system.
