Modified Silicone
濕氣硬化型改性矽膠為(聚醚樹脂所構成的)新型態彈性體接著劑,也是快速固化膠類中,性價比高的接著劑之一。
而濕氣硬化型改性矽膠產品具有下列特色:
@ 無溶劑配方
@ 黏合時具感壓性
@ 固化後具有高彈性
@ 黏著材質廣泛(塑膠、金屬、玻璃等)
@ 優秀的環境耐久性
@ 優秀的機械性質
@ 優秀的低溫性能
相較於傳統PU (Poly Ureathane)產品會使用到含有毒性的異氰酸脂(Isocyanate),濕氣硬化型改性矽膠在硬化的過程中僅會釋放出醇類(alcohol),因此在使用上更加安全。
另外傳統的RTV-1矽膠(Silicone Rubber)具有下列缺點,因此使部分使用者覺得不便。
@ 具有污染性,因其內部的未反應矽油小分子會慢慢地擴散到膠體外界來,在土木應用上會造成建築物的汙損,在電子應用上會造成接點的接觸不良,以及密閉環境應用上的透明基材造成汙染而影響透光度。
@ 硬化時會釋放出較難聞的臭味(如脫酸型及脫肟型)。
@接著能力相對較差,大多用在密封用途上。
而濕氣硬化型改性矽膠在硬化過程中僅會釋出醇類,因此並不會有傳統RTV-1矽膠的污染性及臭味;且由於改性矽膠具有聚醚結構,也使得在接著應用上會比傳統RTV-1還要來得好。
由於濕氣硬化型改性矽膠具有在一般室溫環境即可固化的方便性,使得各類型產業都會廣泛地使用之,目前永寬化學在光學感測模組產業、揚聲器產業、光纖連接器產業、排線補強產業上都有成功的應用,而永寬化學也致力推廣於在6C產業的產品設計上的接著、灌注、密封、補強的應用上,由於永寬化學將濕氣硬化型改性矽膠產品的開發列為研發重點,因此在配方開發、製程技術、產品包裝…等,投入大量的資源,進而來開展這個具前景與多元應用的市場。
Moisture curing modified silicone (Made of Polyether resin) is the new elastomeric adhesive. It is one of high performance-price ratio adhesive in fast curing adhesive.
Moisture curing modified silicone has the following feature:
l Solvent-free formula
l Pressure sensitive when bonding
l High flexibility after curing
l Wide range of adhesive materials (plastic, metal, glass, etc.)
l Excellent environmental durability
l Excellent mechanical properties
l Excellent lower temperature property
The traditional PU (Poly Ureathane) products, it will release the toxic Isocyanate during using. The Moisture curing modified silicone only releases alcohol during the hardening process, it is more safely.
In addition, the traditional RTV-1 silicone rubber has the following disadvantages, it is inconvenient for some users.
l It has pollution because the internal unreacted small molecules will slowly spread to the outside of the rubber. In the civil application, it will cause the stained on the building; Poor contact in electronic applications, the transparent substrate will cause pollution and affects the transmittance on the enclosed space.
l It will release stench when haring(Such as deacidification and deoxime.)
The adhesion is lower, mostly used for sealing.
