(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.

       單組分濕氣固化型聚氨酯密封膠適用于多孔性表面粘接,對玻璃和金屬等非孔性表面,通常需與玻璃活化劑、玻璃底膠、漆面底劑配合使用。為了確保風擋玻璃與車體粘接性能可靠,在玻璃表面涂布底膠是必要的,它可提高聚氨酯密封膠在玻璃層上的粘接強度。

       為了提高施膠速度和質量,目前各大汽車公司均采用機械手自動涂布單組分濕氣固化型聚氨酯密封膠。自動涂膠系統由涂膠泵、計量裝置、機械手、涂膠槍和工作臺組成。為了保證涂膠量的穩定性通常采用帶有加熱系統的壓盤和輸膠管路。使用自動涂膠系統要保證每次更換膠桶時排出空氣,防止出現氣泡,還要確保槍嘴的清潔,保證涂膠量準確。單組分濕氣固化PU風擋玻璃聚氨酯密封膠正在應用和開發的品種有:高模量型單組分PU玻璃聚氨酯密封膠;高接觸粘性型單組分PU玻璃聚氨酯密封膠;預涂單組分聚氨酯密封膠及工藝;硅烷改性PU粘接密封劑;低導電性單組分聚氨酯密封膠,用于防止引起鋁質車體的腐蝕和對天線接收效果的不良影響。www.16878m.com
