(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.

(1)MS密封膠出供箱后黏性維持時間一般為3 min,所以在最短時間內完成粘合可獲得最佳粘接效果。否則,隨時間的延長實體溫度下降,影響粘接效果。
(2)經驗得知,MS密封膠的最佳粘合溫度為48一54℃,低于45℃,鉆性明顯降低;高于65℃,可能造成未枯合完成膠層已矢去翁性。同時,壓合后徐膠邊緣線易產生拉絲,材料間吻合度不好,或因該處張力較大形成脫膠及假性粘接。
(3)最后一道烘箱出口處最好設置保溫罩,以免溫度下降太快,影響粘接牢度。
加壓
(1)加壓的時間長短和壓力高低依鞋型、材質而定。張力大的鞋型,應延長壓合時間,一般在2. 5-3. 0 MPa壓力下壓合10一12 s。
(2)壓合時,使用三合一強式壓合機,一次壓合完成。因為多次壓合產生的剪切力會破壞已粘合的粘接面。
整理
(1)整理時應避免整理用的溶劑滲人粘接面,從而降低粘接強度。
(2)如設置有再加工成型工序,應放置24 h,待MS密封膠反應完成后再進行,以免熱活化時造成脫膠。
