What is the photoinitiator used in composites?

Benzoyl peroxide
Tertiary amines
Camphorquinone
MMA

The correct answer is: Camphorquinone

Camphorquinone is a commonly used photoinitiator in composites due to its high reactivity and ability to be activated by a broad spectrum of light. Unlike the other options, benzoyl peroxide, tertiary amines, and MMA are not photoinitiators and are typically used as comonomers in the composite resin. These substances can act as catalysts for the polymerization process but do not initiate the reaction like a photoinitiator does. Therefore, they are not the correct answer for this question. It is important to accurately identify the photoinitiator used in composites in order to ensure proper and efficient polymerization of the composite material.
