(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.

以減輕汽車自重并減少戶VC涂料用量為目的的低密度PVC抗石擊涂料是該類丁基防水嵌縫膠的一個新品種。如PS7043B車底保護涂料，其密度已降到0.81.02 g/c m3，而同類丁基防水嵌縫膠的密度一般在1,301.5 g/cm3，這樣每輛轎車使用此種丁基防水嵌縫膠將減輕自重3-5 kg據報道就采用這種丁基防水嵌縫膠。

PVC抗石擊涂料的另一技術進步是多功能合一，即其不僅起到防腐蝕作用，也能起到一定的降噪作用，典型丁基防水嵌縫膠是的INS51可噴涂降噪車底涂料，它不僅有較低的密度，而且具有降噪、抗石擊合一的功能，該丁基防水嵌縫膠在面漆烘干溫度下可產生50%的膨脹，其發泡的結構賦予它使噪音衰減的特性，如在8k日Z的頻率下做降噪性試驗，使用INS51涂料后的試板較對照裸板可使噪音水平降低20 dB，提高了司乘人員的舒適感。

由于PVC類丁基防水嵌縫膠在車輛報廢焚燒或車輛事故意外燃燒時會釋放出有毒的氯化氫氣體，對環境和人體健康造成危害，開發應用無PVC樹脂的環保型抗石擊涂料已是當今最新發展趨勢。前幾年率先成功開發出丙烯酸樹脂型車底密封涂料，并已經在多款車型以及汽車公司廣泛使用。此項技術已由國內引進，并將其丁基防水嵌縫膠成功應用于等廠家。此外，聚氨醋類的車底密封涂料在國外發展已經很成熟，國內成功應用的案例是，其丁基防水嵌縫膠由提供。http://www.www.sunsage.net/
