Molecular Structure
Description:
Syna-PI 1173 is a general-purpose radical photoinitiator that can be used alone or in combination with other photoinitiators. It is used in formulations containing unsaturated materials such as acrylates, methacrylates, vinyls and unsaturated polyesters. With exposure to UV light, Syna-PI 1173 undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerization through the unsaturated groups present in the system.
