Abstract

열경화성, 팽창성 일액형 폴리우레탄 조성물이 기재되어 있다. 이들 조성물은 a)실온에서 유동성이고, 유기 폴리이소시아네이트를 폴리히드록실 화합물과 반응시킴으로써 얻어지는 이소시아네이트 프리폴리머；b)분자당 평균 2개 이상의 히드록실기를 갖고, 프리폴리머 상 a)중에서 불용성이고, 그 중 미세하게 분포된 고상의 미분 폴리히드록실 화합물；및 c)프로폴리머 상 a)중에 미세하게 분포된 고상의 미분 취입제로 이루어지며, 단, 취입제 c)의 분해 온도가 이 조성물의 경화 온도보다 그다지 높지 않다.
이들 폴리우레탄 조성물은 또한 d)안료, 촉매, 안정화제, 유동 증지네, 농후화제, 건조제 및 발포 조절제와 같은 보조제 및 첨가제로 이루어질 수 있다.
