säteilykovetteita
Säteilykovetteita, also known as radiation curable coatings or inks, are liquid formulations that harden rapidly when exposed to specific types of radiation. This process, called curing, involves initiating a polymerization reaction within the coating. The primary radiation sources used are ultraviolet (UV) light and electron beams (EB). UV curing relies on photoinitiators within the formulation that absorb UV photons and generate reactive species, typically free radicals or cations, which then propagate the polymerization chain reaction. EB curing uses high-energy electrons to directly initiate the polymerization process without the need for photoinitiators.
The composition of säteilykovetteita typically includes monomers and oligomers, which form the backbone of the hardened
