Liaparo tsa UV tse nang le metsi haholo-holo li kenyelletsa li-resin tsa UV tse tsoang metsing, li-photoinitiators, li-additives le liphahlo tsa mebala.Har'a likarolo tsohle, resin ea UV e nang le metsi e na le tšusumetso e kholo ts'ebetsong ea ho roala ha metsi ka metsi.Ts'ebetso ea resin ea Waterborne UV e ama matla, ho hanyetsa kutu le ho folisa kutloelo-bohloko ea filimi e folisitsoeng e holim'a lesela [1].Resin e thehiloeng metsing e boetse e angoa ke photoinitiator.Tlas'a tšusumetso ea photoinitiator, resin e thehiloeng metsing e ka phekoloa tlas'a leseli.Ka hona, photoinitiator le eona ke karolo ea bohlokoa ea liaparo tsa UV tse nang le metsi.Tlhokahalo ea nts'etsopele ea nakong e tlang ea photoinitiator ke polymerizable le macromolecular.
