The present invention is to provide a coating composition for a polyurethane foam and a polyurethane foam using same, which not only can provide a level of adhesion suitable for an automated process for producing battery packs, but also has a uniform surface, and excellent durability and reliability in a harsh environment. Provided are a coating composition for a polyurethane foam and a polyurethane foam using same, the composition comprising a (meth)acrylate-based monomer, urethane acrylate, a photoinitiator, and inorganic fine particles, wherein the amount of the inorganic fine particles is 100-500 parts by weight with respect to 100 parts by weight of the photoinitiator. La présente invention concerne une composition de revêtement pour une mousse de polyuréthane et une mousse de polyuréthane l'utilisant, qui non seulement peut fournir un niveau d'adhérence approprié pour un procédé automatisé de production de blocs-batteries, mais présente également une surface uniforme ainsi qu'une excellente durabilité et une excellente fiabilité dans un environnement difficile. La composition de revêtement selon l'invention comprend un monomère à base de (méth)acrylate, un acrylate d'uréthane, un photo-initiateur et des particules fines inorganiques, la quantité des particules fines inorganiques étant de 100 à 500 parties en poids par rapport à 100 parties en poids du photo-initiateur. 본 발명은 배터리 팩을 생산하는 자동화 공정에 적합한 수준의 점착성을 제공할 수 있을 뿐만 아니라, 균일한 표면을 갖고 있으며, 가혹환경에서 내구성, 신뢰성이 뛰어난 효과를 갖는 폴리우레탄 폼용 코팅제 조성물 및 이를 이용한 폴리우레탄 폼을 제공하기 위한 것으로, (메트)아크릴레이트계 모노머, 우레탄아크릴레이트, 광개시제 및 무기 미립자를 포함하며, 상기 무기 미립자의 함량은 상기 광개시제 100 중량부 대비 100 중량부 이상 500 중량부 이하인 것인, 폴리우레탄 폼용 코팅제 조성물과 이를 이용한 폴리우레탄 폼이 제공된다.
