Zusammenfassung: | The present invention relates to a photocurable transparent paint composition for PCM with improved weather resistance and, more specifically, to a photocurable transparent paint composition for PCM with improved weather resistance that has eco-friendly characteristics and transparency while solving problems such as gloss reduction, yellowing phenomenon, harmfulness to the human body, quality deterioration, etc. due to the use of the conventional photoinitiator and, in particular, improves main performance such as weather resistance, etc. by synthesizing a self-photocurable intermediate using a Michael addition reaction, preparing a self-photocurable polyurethane acrylate oligomer using the self-photocurable intermediate, and applying the self-photocurable polyurethane acrylate oligomer to the photocurable transparent coating composition for PCM.
본 발명은 내후성이 개선된 PCM용 광경화형 투명 도료 조성물에 관한 것으로, 보다 구체적으로는 마이클 부가(Michael addition) 반응을 이용하여 자가 광경화가 가능한 중간체를 합성하고 이를 이용하여 자가 광경화가 가능한 폴리우레탄 아크릴레이트 올리고머를 제조한 후, 이를 PCM용 광경화형 투명 도료 조성물에 적용함으로써, 종래 광개시제의 사용에 따른 따른 광택저하, 황변 현상, 인체 유해성, 품질저하 등의 문제를 해결하면서도 친환경적 특성과 투명성을 가질 뿐만 아니라, 특히 내후성 등의 주요 성능을 향상시킬 수 있도록 하는, 내후성이 개선된 PCM용 광경화형 투명 도료 조성물에 관한 것이다. |
