Abstract

UV-Curing technology can be classified into two categories for radical curing and cation curing. It also has mainly focused on surface finishing technology to improve functionality of various substrates such as plastics and metals. On the other hand, EB technology has dealt with cross-linking reactions as well as polymerization process to create novel functional materials. Both technologies have advantages in energy utilizing efficiency and environmental friendly when compared to conventional thermoset coatings. Consequently, UV cured coatings also permits a reduction in the $CO_2$ and VOCs emitted in the drying and curing process. This review mainly shows radical curing technology which is commonly used in UV curing coatings and also describes the technology trends of cation curing which has been attracted attention recently.

UV 경화기술은 라디칼 경화와 양이온 경화로서 크게 2 종류로 분류할 수 있다. 이 기술은 플라스틱과 금속간의 여러 기재에 대한 기능성을 개선하기 위해서 표면처리기술에 주로 초점이 맞추어져 왔다. 반면에, Electron beam 기술은 새로운 기능성 재료들을 창출하기 위해 중합공정뿐만 아니라 가교반응들을 다루었다. 이들 두 기술들은 종래의 열경화성 코팅과 비교할 때, 에너지이용 효율과 환경 친화적이어서, 건조와 경화 공정으로 부터 배출되는 탄산가스와 휘발성 유기물을 대폭 감소시킨다. 이 논문에서는 UV 경화 코팅에서 흔히 사용되는 라디칼 경화기술과, 최근의 있는 양이온 경화와 관련된 기술을 다룬 리뷰 논문이다.
