Abstract

본 발명은 자외선 경화형 도료 조성물에 관한것으로서, 실란변성에폭시 아크릴레이트 올리고머, 반응성모노머 광개시제, 레벨링제 및 첨가제로 구성되며 자외선 경화형바니쉬 경화물이 갖기 쉬운 경도, 내세제성, 내마모성, 내스크래치성, 내후성등의 물성저하와 도장시 작업성 불량을 크게 개선한 것으로서 특히 열경화형 도료가 도막을 형성하기 위해 장시간 가열시 물성 변화가 적게 되어 도장시 작업성이 우수한 자외선 경화형 도료 조성물을 제공한다.The present invention relates to a UV-curable coating composition, comprising a silane-modified epoxy acrylate oligomer, a reactive monomer photoinitiator, a leveling agent and an additive, the hardness, detergent, abrasion resistance, scratch resistance, weather resistance, etc. It is a significant improvement in physical property degradation and poor workability during painting, and in particular, the thermosetting paint provides a UV-curable coating composition having excellent workability during coating due to a small change in physical properties when heated for a long time to form a coating film.
