環氧－酚醛膠的優點是性能較全面，耐高低溫、耐熱老化、大氣老化和濕熱老化。主要缺點是脆性大。有機硅樹脂的硅氧烷基能與環氧樹脂的羥基反應，改型物具有有機硅和環氧樹脂的雙重優點。 增韌劑 耐高溫粘結劑由于大分子的剛性和交聯密度高所以脆性大，影響了粘結強度，尤其是線受力強度，因此需要增韌。通常的增韌劑有端羧基丁腈橡膠、聚酚氧樹脂、聚砜樹脂等。通常隨著韌性的增加，耐熱性會降低。近年來采用熱塑性耐熱性樹脂如聚芳砜、聚醚酮、聚醚醚酮等；來增韌，隨著韌性的提高耐熱性基本不下降，甚至還略有提高。 填料 超細純鋁粉能顯著提高粘結強度。氣相二氧化硅能控制流動性。常用的填料還有硅微粉和立德粉等。 抗氧化劑 被粘結的金屬離子如銅、鐵離子在高溫下有催化有機高分子的熱氧化分解反應，造成界面粘結破壞。為了消除金屬離子的催化降解活性，提高耐熱性，常加入金屬離子鰲合劑如8－羥基喹啉、沒食子酸丙酯、乙酰基丙酮、鄰苯二酚等。他們可以捕捉這些金屬離子，從而減弱金屬離子的催化降解作用。某些砷、錳、鉬的氧化物也能有效的降低金屬離子的活性如As2O5能于Fe離子生成很穩定的砷鐵鹽。
環氧樹脂高溫(wen)粘結(jie)(jie)劑的(de)定(ding)(ding)義、分類及(ji)評價在國內外至今沒有(you)統一的(de)標準。一般說來，耐高溫(wen)性應按照(zhao)在特定(ding)(ding)的(de)溫(wen)度、時間和介質中能保持(chi)設計(ji)所需要的(de)粘結(jie)(jie)強(qiang)度，或具有(you)一定(ding)(ding)的(de)強(qiang)度保持(chi)率來評價。
與其他(ta)耐高溫(wen)粘結劑相比教(jiao)，耐高溫(wen)環氧樹脂(zhi)粘結劑的特點是；膠接強度高，綜合性能(neng)好(hao)，使(shi)用工(gong)藝簡單。突出的優(you)點是固(gu)化過程(cheng)中(zhong)揮發份少(shao)，僅0.5～1.5％左(zuo)右，收(shou)縮率小，一(yi)般(ban)在0.05～0.1～左(zuo)右。可(ke)在-60℃～232℃下(xia)長期使(shi)用，最(zui)高工(gong)作溫(wen)度可(ke)達260～316℃。
