Abstract Peelable coatings, as the name suggests, are temporary coatings which can be peeled off as continuous and sizable sheets from the substrate at the end of the service period. These coatings, also known as strippable coatings, have proven to be a cost-effective and time-efficient solution for protection and decontamination of sensitive, and inaccessible surfaces requiring a high precision application method. These coatings are removable and flexible but are robust and impervious to external chemical attacks and physical stresses. Peelable coatings due to their compatibility with a wide range of substrates can be applied on metals, plastics, glass and concrete, to name a few. The polymers predominantly used for peelable coating composition include vinyl-based polymers and copolymers, acrylics, polyurethanes, cellulose polymers and derivatives in a water-based or solvent-based system. Another key ingredient of the peelable coating system is the release agent used. Release agents play a cardinal role in the coating as they restrict the adhesion of the film to the substrate and supplement the peel ability of the film. Coupling the polymer chemistries, release agents with different additives can yield a broad spectrum of peelable coatings finding applications in decontamination of nuclear reactors, optics, automotive, floor coatings, electronic protection, food coatings, cosmetics and labels for plastics.

可剥离涂层：综述

摘要 可剥离涂层，顾名思义，是一种临时涂层，可在使用期结束时从基材上剥离成连续且相当大的片状。这些涂层，也称为可剥离涂层，已被证明是一种经济高效且省时的解决方案，用于保护和净化敏感且难以接近的表面，需要高精度的应用方法。这些涂层可移除且柔韧，但坚固耐用且不受外部化学侵蚀和物理应力的影响。可剥离涂层因其与多种基材的兼容性而可应用于金属、塑料、玻璃和混凝土，仅举几例。主要用于可剥离涂料组合物的聚合物包括乙烯基聚合物和共聚物、丙烯酸、聚氨酯、水基或溶剂基系统中的纤维素聚合物和衍生物。可剥离涂层系统的另一个关键成分是所使用的脱模剂。脱模剂在涂层中发挥着重要作用，因为它们限制了薄膜与基材的粘附并补充了薄膜的剥离能力。将聚合物化学、脱模剂与不同添加剂相结合，可以产生广泛的可剥离涂层，可用于核反应堆、光学、汽车、地板涂料、电子保护、食品涂料、化妆品和塑料标签的净化。脱模剂在涂层中发挥着重要作用，因为它们限制了薄膜与基材的粘附并补充了薄膜的剥离能力。将聚合物化学、脱模剂与不同添加剂相结合，可以产生广泛的可剥离涂层，可用于核反应堆、光学、汽车、地板涂料、电子保护、食品涂料、化妆品和塑料标签的净化。脱模剂在涂层中发挥着重要作用，因为它们限制了薄膜与基材的粘附并补充了薄膜的剥离能力。将聚合物化学、脱模剂与不同添加剂相结合，可以产生广泛的可剥离涂层，可用于核反应堆、光学、汽车、地板涂料、电子保护、食品涂料、化妆品和塑料标签的净化。
