본 개시내용은 기재 상에 n-아실 우레아 코팅을 형성하기 위한 용매계 시스템을 제공한다. 한 실시양태에서, 용매계 시스템은 폴리카르보디이미드-폴리우레탄 하이브리드를 포함한다. 용매계 시스템은 또한 산 관능성 중합체 및 유기 용매를 포함하고, 상기 용매계 시스템의 총 중량을 기준으로 하여 10 중량% 이하의 물을 포함한다. 용매계 시스템은 또한 백만 중량부의 용매계 시스템 당 약 100 중량부 미만의 톨루엔 디이소시아네이트를 포함한다. This disclosure provides a solvent-borne system for forming an n-acyl urea coating on a substrate. In one embodiment, the solvent-borne system comprises a polycarbodiimide-polyurethane hybrid. The solvent-borne system also comprises an acid functional polymer and an organic solvent, and comprises less than or equal to 10 weight percent of water based on a total weight of said solvent-borne system. The solvent-borne system also comprises less than about 100 parts by weight of toluene diisocyanate per one million parts by weight of the solvent-borne system.
