表面保护膜形成残胶的机理和对策

Formation mechanism and solutions of residual gum for surface protective film

对丙烯酸酯压敏胶表面保护膜的内聚破坏、粘基破坏、迁移残留等3种残胶现象进行了分类说明,提出了剥离强度经时变化、老化、与被保护表面相容、拉伸效应、黏弹性效应等5种残胶的机理,并提出了相应的解决方案。

This article described three types residual gum, such as dropping from PSA or substrate, and migrating from PSA. Then, five type mechanisms of forming residual gum were analyzed, and based on that, some solutions were provided.
