    안녕하세요. 좀 궁금한게 있어서 문의 드립니다. 

     

    제가 진행하는 Test가 있었는데 하기의 내용과 같이 

     

    PET/PET/PE로 구성된 Sheet를 평평한 Plate에 붙혀서 온도 85도 습도 85% 조건으로 가열 Test를 하던 중에 

     

    약 1500시간에서 제일 윗쪽의 PET가 박리되어 주름이 발생했습니다.(모서리 부분만) 

     

    접착제는 폴리우레탄 소제를 사용했는데, 혹시 이게 고온 또는 고습도 상태에서 박리가 될수 있는지

     

    그리고 주름 형태를 봤을때 PET 소재가 팽창한 것으로 보이는데, 그렇게 보는게 맞는지 문의 드립니다.

     

    감사합니다.
