본 발명의 실시예는 낮은 음극 박리 코팅 조성물, 특히 낮은 음극 박리를 갖는 폴리우레탄 코팅을 형성하는데 이용될 수 있는 부틸렌 옥사이드계 폴리올 조성물을 포함하는 폴리우레탄 조성물에 관한 것이다. 예로서, 낮은 음극 박리 코팅 조성물은 부틸렌 옥사이드계 폴리올 조성물을 포함하는 폴리올 조성물 및 폴리이소시아네이트 조성물을 포함하는 폴리우레탄 조성물로부터 형성될 수 있으며, 상기 폴리올 조성물은 2 내지 8의 평균 히드록실 작용가 및 150 내지 4000의 히드록실 당량을 가지며, 상기 부틸렌 옥사이드계 폴리올 조성물은 폴리올 조성물의 총 중량의 10 중량% 내지 100 중량%이고 평균 히드록실 작용가가 2 내지 3이고, 상기 폴리우레탄 조성물은 70 내지 120의 이소시아네이트 지수를 갖는다. Embodiments of the present disclosure are directed to low cathodic disbondment coating compositions, more particularly, to polyurethane compositions including a butylene oxide based polyol composition that can be utilized to form polyurethane coatings having low cathodic disbondment. As an example, a low cathodic disbondment coating compositions can be formed from a polyurethane composition including a polyol composition that includes a butylene oxide based polyol composition, where the polyol composition has an average hydroxyl functionality from 2 to 8 and a hydroxyl equivalent weight from 150 to 4000, where the butylene oxide based polyol composition is from 10 weight percent to 100 weight percent of a total weight of the polyol composition and has an average hydroxyl functionality from 2 to 3, and a polyisocyanate composition, where the polyurethane composition has an isocyanate index in a range from 70 to 120.
