Title (EN) HIGHLY ELASTIC POLYESTER MODIFIED URETHANE RESIN, AND CLEAR COAT COMPOSITION CONTAINING SAME
(FR) RÉSINE URÉTHANE MODIFIÉE PAR UN POLYESTER HAUTEMENT ÉLASTIQUE ET COMPOSITION DE REVÊTEMENT TRANSPARENT LA CONTENANT
(KO) 고탄성 폴리에스터 변성 우레탄 수지 및 이를 포함하는 클리어코트 조성물
Abstract: front page image
(EN)The present invention relates to: a highly elastic polyester modified urethane resin; and a clear coat composition containing the same and, more specifically, to: a highly elastic polyester modified urethane resin with improved chipping resistance by introducing an aliphatic isocyanate and caprolactone polyol into a polyester resin; and a clear coat composition containing the polyester modified urethane resin as a base resin, thereby eliminating a separate intermediate coating layer formation step and, compared with a conventional coating method, ensuring a satisfactory coat appearance and excellent mechanical properties such as scratch resistance, weather chipping resistance and impact resistance.
(FR)La présente invention concerne : une résine uréthane modifiée par un polyester hautement élastique; et une composition de revêtement transparent la contenant, et plus particulièrement : une résine uréthane modifiée par un polyester hautement élastique présentant une résistance à l'écaillage améliorée par l'introduction d'un isocyanate aliphatique et d'un polyol de caprolactone dans une résine polyester; et une composition de revêtement transparent contenant la résine uréthane modifiée par un polyester en tant que résine de base, ce qui permet d'éliminer une étape de formation de couche de revêtement intermédiaire séparée, comparativement à un procédé de revêtement classique, ce qui permet de garantir une apparence de revêtement satisfaisante et d'excellentes propriétés mécaniques telles que la résistance aux rayures, la résistance à l'écaillage dû aux conditions climatiques et la résistance aux chocs.
(KO)본 발명은 고탄성 폴리에스터 변성 우레탄 수지 및 이를 포함하는 클리어코트 조성물에 관한 것으로서, 보다 상세하게는 폴리에스터 수지에 지방족 이소시아네이트 및 카프로락톤 폴리올을 도입하여 내치핑성이 향상된 고탄성 폴리에스터 변성 우레탄 수지 및 상기 폴리에스터 변성 우레탄 수지를 주제수지로 포함함으로써 별도의 중도 도막층 형성 공정을 생략할 수 있고, 기존의 도장공법과 비교하여 양호한 도막외관과 스크래치성, 내한치핑성, 충격성 등의 우수한 기계적 물성을 확보할 수 있는 클리어코트 조성물에 관한 것이다.
