(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

挤胶后10分钟内，安装玻璃，以免二次污染或玻璃专用硅烷改性聚氨酯密封胶发生表干现象。抹底涂及挤胶前须保证玻璃及窗框干燥。

8693聚氨酯吸潮固化型玻璃硅烷改性聚氨酯密封胶安装完24小时后再启动车辆，保证玻璃有足够时间固化。

通常8693硅烷改性聚氨酯密封胶在温度25℃，湿度50%的情况下，24小时后会完全固化。若遇特殊天气情况，可适当延长固化时间。

标准挡风玻璃安装位置的调节。将更换的挡风玻璃放到窗框上。调整挡风玻璃，使其很好地嵌入整个窗框里，在挡风玻璃上和车身上粘贴遮蔽胶带，标出这一位置。剪开玻璃边缘的胶带。如图2所示。卸下挡风玻璃，待打完玻璃胶可有效快速地在正确的位置安装玻璃。

储存注意事项

8693聚氨酯汽车玻璃密封胶储存于4.4℃一26℃之间。滚动库存基于“先进先出”原则。在推荐条件下储存时，未开启的产品可储存12个月。

硅烷改性聚氨酯密封胶目前广泛地应用于塑料管道密封、机械防漏、汽车维修等化工领域，因为性价比高、粘接性好、性价比高、施工工艺简洁等先天优势，在胶粘剂市场上深受消费者喜爱。硅烷改性聚氨酯密封胶目前工艺技术成熟、产能产量初具规模，但与此同时品垫片胶、高分子胶等同类相似产品也在迅速发展，这些产品在性能与价格方面向硅烷改性聚氨酯密封胶提出严峻的挑战。为了进一步提高产品性能、降低生产成本，生产企业在硅烷改性聚氨酯密封胶的生产过程中加人大量的填料，这对硅烷改性聚氨酯密封胶长期贮存不分层、浮色提出了更高的要求。相比于溶剂、气相粉，填料比重大很容易沉降分层，如果填料使用量不合理，胶液在后期的运输、储存过程中出现不同程度的分层和浮色，不仅影响产品开罐效果，也给施工质量带来极大隐患。硅烷改性聚氨酯密封胶分层浮色影响因素探讨尤为重要，本文通过对密封胶主要原料橡胶、填料、溶剂、偶联剂等几个逐一探索，在历经大量试验发现经过合理的配方搭配，添加填料的硅烷改性聚氨酯密封胶综合性能优异、贮存性能良好。http://www.sdyuantai.com/
