금속 쉘이 있는 배터리 디바이스를 패키징하는 방법으로서, 수계 2-성분 폴리우레탄 조성물을 배터리 디바이스의 금속 쉘에 적용하는 단계, 및 적용된 폴리우레탄 조성물을 건조시켜 패키징 층을 형성하는 단계를 포함하며; 상기 폴리우레탄 조성물은 (A) 하이드록실-작용성 중합체를 포함하는 수성 분산액 - 여기서 하이드록실-작용성 중합체는 하이드록실-작용성 중합체의 중량을 기준으로 20 중량% 내지 50 중량%의 하이드록시-작용성 알킬 (메트)아크릴레이트의 구조 단위; 0.1 중량% 내지 10 중량%의 산 단량체, 이의 염 또는 이들의 혼합물의 구조 단위; 및 모노에틸렌계 불포화 비이온성 단량체의 구조 단위를 포함함 -; 및 (B) 폴리이소시아네이트를 포함하는, 방법. A method of packaging a battery device with a metal shell, comprising: applying a waterborne two-component polyurethane composition to the metal shell of the battery device, and drying the applied polyurethane composition to form a packaging layer; wherein the polyurethane composition comprises, (A) an aqueous dispersion comprising a hydroxyl-functional polymer, wherein the hydroxyl-functional polymer comprises, by weight based on the weight of the hydroxyl-functional polymer, from 20% to 50% of structural units of a hydroxy-functional alkyl (meth)acrylate; from 0.1% to 10% of structural units of an acid monomer, a salt thereof, or mixtures thereof; and structural units of a monoethylenically unsaturated nonionic monomer; and (B) a polyisocyanate.
