陶氏DOW硅酮密封胶DOWSIL™ 983 Structural Glazing Sealant Base and Curing Agent

专为工业玻璃和幕墙生产需要双结构和耐候密封应用的专业用途而设计。一旦固化，这种结构密封胶形成一种耐用，柔韧，不透水的粘合剂，可保证20年，并用于±25％运动的耐候密封应用。虽然DOWSIL™r-C OS可以快速和一致地粘合，但它具有优异的未涂底漆对玻璃，铝和阳极氧化铝1的附着力，特别是对于Kynar™和其他批准用于建筑结构玻璃应用的高性能基材。

Designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in ±25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum1, although DOWSIL™ r-C OS is recommended for fast and consistent adhesion, especially to Kynar™ and other high-performance substrates approved for architectural structural glazing applications.
