用于压敏粘合剂（PSA）的SYL-OFF™氟硅橡胶离型涂层解决方案

有机硅压敏粘合剂（PSA）具有独特的优势，使其成为具有挑战性的高价值应用的理想选择。通过陶氏的各种氟硅橡胶离型涂层解决方案和PSA的相辅相成，您可以：

扩展PSA的粘合性能，适用于新的应用和产品。
满足不断变化的客户需求并进入新市场。
为您的应用实现经济和性能的最佳平衡。

此外，SYL-OFF™氟硅橡胶离型涂层旨在为DOWSIL™有机硅压敏粘合剂提供一致、稳定的脱模。

采用 SYL-OFF™氟硅橡胶衬里的典型胶带结构

插入性能

将陶氏有机硅压敏粘合剂浇铸并固化到载体膜上，并在固化步骤之后将氟硅橡胶离型衬里夹在中间。
低离型力允许通过手动或半自动生产线轻松去除衬里。

转移涂料性能

对于薄、易碎或热敏薄膜，转移涂料可能是一种选择。一些有机硅压敏粘合剂可直接涂覆在具有陶氏氟硅橡胶涂层的薄膜上，以满足苛刻的涂敷和固化过程。可以将这些薄膜夹在PSA上，从而将PSA从衬里转移到载体上。

差异离型

双面、不支持的或转移胶带通常需要差异离型，以避免在应用过程中出现混淆。一种选择是使用直接铸造和夹持衬里之间的差异来获得比例为1.2-2.5的差异，具体取决于应用。
