Title
(EN) SURFACE PROTECTION FILM
(FR) FILM DE PROTECTION DE SURFACE
(JA) 表面保護フィルム
Abstract
(EN)
Provided is a surface protection film which does not readily peel off the adherend and can be inhibited from coming to have an extremely high peel force with the lapse of time even when having a high initial peel force just after application to the adherend, and the application of which to adherends less soils the adherend surfaces. The surface protection film of the present invention includes a pressure-sensitive adhesive layer. This surface protection film, when applied to a glass plate by bonding the pressure-sensitive adhesive layer to the glass plate, allowed to stand at 23°C for 30 minutes, and then peeled at 23°C from the glass plate at a peel angle of 180° and a peel rate of 300 mm/min, has a peel force A of 0.024-0.50 N/25 mm. This surface protection film, when applied to a glass plate by bonding the pressure-sensitive adhesive layer thereof to the glass plate, allowed to stand at 100°C for 2 days, and then peeled at 23°C from the glass plate at a peel angle of 180° and a peel rate of 300 mm/min, has a peel force, which is expressed by B. Then the surface protection film has a degree of peel force increase with time, which is calculated by (B/A)×100, of 1,000% or less.

L'invention concerne un film de protection de surface qui ne se décolle pas facilement de la partie à coller et peut être empêché d'avoir une force de pelage extrêmement élevée avec l'écoulement du temps même lorsqu'il présente une force de pelage initiale élevée juste après l'application sur la partie à coller, et dont l'application aux parties coller salit moins les surfaces des parties à coller. Le film de protection de surface de la présente invention comprend une couche adhésive autocollante. Ce film de protection de surface, lorsqu'il est appliqué à une plaque de verre par liaison de la couche adhésive autocollante à la plaque de verre, est laissé reposer à 23 °C pendant 30 minutes, puis pelé à 23 °C de la plaque de verre à un angle de pelage de 180° et une vitesse de pelage de 300 mm/min, a une résistance au pelage A de 0,024 à 0,50 N/25 mm. Ce film de protection de surface, lorsqu'il est appliqué sur une plaque de verre par liaison de la couche adhésive autocollante de celui-ci à la plaque de verre, est laissé reposer à 100 °C pendant 2 jours, puis pelé à 23 °C de la plaque de verre à un angle de pelage de 180° et une vitesse de pelage de 300 mm/min, a une force de pelage, qui est exprimée par B. Alors le film de protection de surface a un degré d'augmentation de la résistance au pelage avec le temps, qui est calculé par (B/A) x 100, de 1 000 % ou moins.

被着体から容易に剥がれることがなく、被着体に貼り付けた後の初期の剥離力が大きくても経時における重剥離化を抑制でき、被着体に貼り付けることによる該被着体表面の汚染性が低い、表面保護フィルムを提供する。 本発明の表面保護フィルムは、粘着剤層を有する表面保護フィルムであって、該表面保護フィルムの該粘着剤層をガラス板に貼り合わせて温度23℃で30分間放置した後に、温度23℃で該表面保護フィルムを該ガラス板から剥離角度180度、剥離速度300mm/分で剥がした際の剥離力Aが0.024N/25mm~0.50N/25mmであり、該表面保護フィルムの該粘着剤層をガラス板に貼り合わせて温度100℃で2日間放置した後に、温度23℃で該表面保護フィルムを該ガラス板から剥離角度180度、剥離速度300mm/分で剥がした際の剥離力をBとしたときに、(B/A)×100で算出される剥離力経時上昇率が1000%以下である。
