(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.

為滿足裝配式建筑墻體修復接縫時防水密封膠的性能要求，制備雙組分MS密封膠、聚氨酯密封膠，通過試驗分析為這2種密封膠選擇適合的催化劑、觸變劑用量;并對比分析2種密封膠的粘接性能、老化條件下的溶脹情況。
(1)常溫下催化劑質量分數為0. 25%時，聚氨酯密封膠表干時間為0. 4 h。溫度為(38士1)℃時，雙組分MS密封膠表于時間較短，催化劑質量分數為0. 75%時，表干時間0. 75 h ;
(2)雙組分MS密封膠、聚氨酯密封膠均應將聚酞胺蠟作為首選觸變劑;
(3)底涂可對密封膠的粘接性能起到保護作用，提升密封膠的防水性能，有底涂的雙組合MS密封膠性能優于有底涂的聚氨酯密封膠;
(4)聚氨酯密封膠更容易受到紫外老化的影響。紫外老化條件下，雙組合MS密封膠溶脹倍率呈低一高一低一高趨勢變化。www.www.lustload.com
