Title (EN) ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE
(KO) 점착 시트
Abstract:
(EN) The present invention provides an adhesive sheet which has a tangent delta (Tan delta) value of 0.3 (inclusive) to 1 (exclusive) at 25°C, and when the adhesive sheet is adhered on one side thereof to a vertically standing SUS substrate with an adhered area of 10mm×10mm, autoclaved at 50°C and five atmospheres for 20 minutes and then cured at room temperature for 24 hours, and subsequently a 4.9N weight is vertically hung from the adhesive sheet and left for one hour, has a ratio of the pushed area to the initial adhered area of 0.1 to 5 %. The adhesive sheet according to the present invention has excellent durability and improved flexural resistance.
(FR) La présente invention concerne une feuille adhésive qui a une valeur de tangente delta (Tan delta) de 0,3 (inclus) à 1 (exclusive) à 25 °C, et lorsque la feuille adhésive est collée sur un côté de celle-ci à un substrat SUS vertical ayant une zone collée de 10 mm x 10 mm, autoclavée à 50 °C et cinq atmosphères pendant 20 minutes puis durcie à température ambiante pendant 24 heures, puis après cela lorsqu'un poids de 4.9 N est suspendu verticalement à la feuille adhésive et laissé pendant une heure, ladite feuille adhésive a un rapport de la zone poussée à la zone collée initiale de 0,1 à 5 %. La feuille adhésive selon la présente invention présente une excellente durabilité et une résistance à la flexion améliorée.
(KO) 본 발명은 25℃에서의 탄젠트 델타(Tan delta) 값이 0.3 이상 1 미만이며, 수직 방향으로 세운 SUS 기재에 접착 면적이 10mm×10mm가 되도록 점착 시트의 일면을 접착시키고, 50℃, 5기압에서 20분 동안 오토클레이브 처리한 후, 상온에서 24시간 양생시킨 다음, 상기 점착 시트에 4.9N의 추를 수직 방향으로 걸고 1시간 동안 방치한 후의 초기 접착 면적 대비 밀린 면적의 비율이 0.1 내지 5%인 점착 시트를 제공한다. 본 발명에 따른 점착 시트는 내구성이 우수하고 내굴곡성이 향상된다.
