3M 468MPR
描述信息
3M 200MP是图形附件和薄膜开关应用的流行选择，因为它具有优异的质量、一致性和耐用性此外，由于3M的创新，专利过程，3M胶粘剂200MP也提供了以下卓越的性能特点
清晰(几乎没有包含在传统的溶剂涂层技术产生的胶粘剂中常见的蒸汽夹杂物)
优异的高温性能和优异的抗剪强度(能最大限度地减少边缘的抬升和滑移)
对恶劣环境的优良抵抗力;该胶粘剂可承受有机溶剂、弱酸、碱、盐水、清洗液、杀菌、消毒剂、油等的溅污此外，它还能在潮湿和热/冷循环后表现良好
当连接到塑料部件(非金属)时，可以提供一些初始的重新定位能力，如果初始对准不正确，则可以将图形部件提升并重新定位最后，该胶粘剂系列提供了多种衬垫配置，以确保良好的工艺灵活性
