Description
[評価法]
粘着力(アクリル板):
アクリル板を幅50ミリメートル(mm)、長さ125ミリメートル(mm)に切断し、この試験板に2kgのゴムローラーを用いて貼り付ける。次いで、300mm/分の速度で剥離(180度剥離)した時の剥離力を測定し、50ミリメートル(mm)幅あたりの剥離力を粘着力(N/50mm)とする。
粘着力(凹凸板):
日新製鋼株式会社製ステンレススチールHL仕上げ#180に保護フィルムを貼り付け、300mm/分の速度で剥離(180度剥離)した時の剥離力を測定し、50ミリメートル(mm)幅あたりの剥離力を粘着力(N/50mm)とする。
巻き戻し力:
ロール状サンプルを用い、300mm/分の速度でロールから引き剥がす時の剥離力(N/50mm)を測定し、巻き戻し力とする。
