Abstract

본 발명은, 선형 카르복실기-함유 폴리에스테르와 글리시딜기-함유 아크릴계 공중합체의 혼합물을 결합제로서 함유하는 분말 열경화성 조성물에 관한 것이다. 폴리에스테르는 20 내지 500mg KOH/g의 산가를 갖고, 아클리계산 공중합체는 5 내지 30중량%의 글리시딜 아크릴레이트 또는 글리시딜 메타크릴레이트, 및 70 내지 95중량%의 메틸 메타크릴레이트로부터 얻어지며, 메틸 메타크릴레이트의 25중량%는 또다른 비닐 단량체로 치환될 수 있고, 상기 아크릴계 공중합체는 약 4,000 내지 약 10,000의 수평균 분자량(Mn)을 갖는다. 상기 조성물은 정전 분무기에 의해 도포되고 약 160 내지 210℃의 온도에서 경화되어 양질의 무광택 피니시를 생성시킬수 있는 분말 페인트 및 니스의 제조를 위해 특히 유용하다.
