Fotoinitiaattorien
Fotoinitiaattorien, or photoinitiators, are molecules that absorb light energy and subsequently initiate a chemical reaction. This process is commonly known as photoinitiation. When exposed to specific wavelengths of light, a photoinitiator undergoes a photochemical transformation, typically leading to the generation of reactive species such as free radicals or cations. These reactive species then propagate a chain reaction, causing the polymerization or crosslinking of monomers or oligomers present in a formulation.
The choice of photoinitiator depends on several factors, including the type of light source used (e.g., UV
Fotoinitiaattorien are crucial components in various applications, most notably in UV-curable coatings, inks, adhesives, and 3D
