      有機矽膠黏劑( Silicone Adhesive)可分為以矽樹脂為基料的膠黏劑和以有機矽彈性體為基料的膠黏劑(包括密封劑)兩類。二者的化學結構有所區別,矽樹脂是由矽‐氧鍵為主鏈的三向結構組成,在高溫下可進一步縮合成為高度交聯的硬而脆的固體;而有機矽彈性體是一種線型的以矽‐氧鍵為主鏈的高分子量的橡膠態物質。室溫硫化矽橡膠種類繁多。根據包裝形式,可分為單組分和雙組分室溫硫化矽橡膠。前者是將基礎聚合物、填料、交聯劑或催化劑在無水條件混合均勻,密封包裝、遇大氣中濕氣進行交聯反應。後者是將基礎膠料和交聯劑或催化劑分開包裝,使用時按一定配比混合就發生交聯。根據固化機理,又可分為縮合型、加成型室溫硫化橡膠兩大類。根據固化時放出的氣體,又可分為脫酸型、脫肟型、脫醇型、脫酮型等。各類有機矽膠黏劑的優缺點見下表。
