(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.

表干時間是研究丁基防水嵌縫膠性能的重要指標之一，表干時間過長，丁基防水嵌縫膠會在基材表面流動給施工帶來不便，同時也影響后期的固化速度;而表干時間過短，也會對施膠過程產生一定影響，還未完成施工就已固化，從而浪費資源，因此，適宜的表干時間尤為重要。本文通過摻人不同質量的PADE,研究了對丁基防水嵌縫膠表干時間的影響，結果如圖4所示。
PADS-0 C純E-51丁基防水嵌縫膠的表干時間較長，為59 min。而隨著PADE摻人量的增加，丁基防水嵌縫膠的表干時間逐漸縮短。當PADE摻人量為10%時，表干時間僅為29 min(理論依據見后文分析)，比未添加PADE的丁基防水嵌縫膠表干時間縮短了30 min，滿足丁基防水嵌縫膠的施工條件。
不同PADE添加量下環氧丁基防水嵌縫膠的硬度測試
硬度是衡量丁基防水嵌縫膠是否合格的一個重要指標，它主要取決于基體樹脂中填料的添加量8。而本文填料的添加量均保持一致，摻人不同PADE的密封膠硬度測試結果，如表2所示。
添加PADE后的丁基防水嵌縫膠較純E-51丁基防水嵌縫膠的硬度基本保持一致，均大于75邵D硬度，達到丁基防水嵌縫膠合格指標。結合不同PADE添加量下環氧丁基防水嵌縫膠的紅外譜圖可知，5種丁基防水嵌縫膠均已完全固化。http://www.caffertyclinic.com/
