(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.

采用直接粘接法進(jìn)行轎車和高檔客車擋風(fēng)玻璃的裝配,是現(xiàn)今國內(nèi)外汽車廠家已普遍采用的一種先進(jìn)技術(shù)。與傳統(tǒng)的橡膠密封條固定擋風(fēng)玻璃的裝配工藝相比,它不僅具有固定強(qiáng)度高、密封性能好、外表美觀大方等特點,而且具有裝配自動化程度高、適合流水線生產(chǎn)作業(yè)的優(yōu)勢。單組分濕氣固化型聚氨酯粘接MS密封膠是最理想的MS密封膠,這種MS密封膠由美國Essex化學(xué)公司于20世紀(jì)70年代最先開發(fā)研制成功,并作為聚硫橡膠MS密封膠的替代產(chǎn)品最早在美國通用汽車公司得到應(yīng)用。此后日本Sunstar化學(xué)工業(yè)株式會社、瑞士Sika公司和法國Revc。公司等相繼成功開發(fā)應(yīng)用。
早期的單組分聚氨酯擋風(fēng)玻璃膠通常需與玻璃底劑和漆面底劑配套使用,經(jīng)濕氣固化后的膠料,要求其粘接剪切強(qiáng)度大于3.5 MPa拉伸強(qiáng)度大于5.0 M Pa斷裂伸長率達(dá)350%以上,另要求在室溫下能快速固化,操作堆積性要好,通常條件下貯存期6個月以上。由于這些獨特性能和工藝性能的苛刻要求,加之國內(nèi)原料和設(shè)備的缺乏,研制和生產(chǎn)這種產(chǎn)品非常困難,上世紀(jì)80年代后期到90年代初期,國內(nèi)當(dāng)時引進(jìn)車型擋風(fēng)玻璃的粘接裝配所用的單組分聚氨酯密封膠完全靠進(jìn)口,如的WS-100聚氨酯密封膠車用的是聚氨酯密封膠等。http://www.m.n5224.cn/
