其實環氧樹脂在20世紀40年代末的一次商業化生產后，成為一個廣泛的材料家族。環氧樹脂由于其高強度、多功能性和優異的表面附著力，在涂料、電氣、鑄造樹脂、復合材料等領域得到了廣泛的應用。

　　In fact, epoxy resin has become a wide family of materials after the primary commercial production in the late 1940s. Epoxy resin has been widely used in coatings, electrical, casting resin, composite materials and other fields because of its high strength, versatility and excellent surface adhesion.

　　熱固性樹脂，即熱固性樹脂，是一種利用熱或輻射等固化方法固化或固化成硬形狀的聚合物。固化過程是不可逆的，因為它引入了由共價化學鍵交聯的聚合物網絡。

　　Thermosetting resin, that is, thermosetting resin, is a kind of polymer which is cured or cured into hard shape by curing method such as heat or radiation. The curing process is irreversible because it introduces polymer networks crosslinked by covalent chemical bonds.

　　與熱塑性塑料不同的是，在加熱時，熱固性會保持固態，直到溫度達到熱固性開始降解的程度。

　　Unlike thermoplastics, thermosets remain solid when heated until the temperature reaches the point where thermosetting begins to degrade.

　　酚醛樹脂、氨基樹脂、聚酯樹脂、硅樹脂、環氧樹脂和聚氨酯(聚酯、乙烯基酯、環氧樹脂、雙馬來酰亞胺、氰酸酯、聚酰亞胺和酚醛樹脂)是熱固性樹脂的少數例子。

　　Phenolic resin, amino resin, polyester resin, silicone resin, epoxy resin and polyurethane (polyester, vinyl ester, epoxy resin, bisMaleimide, cyanoate, polyimide and phenolic resin) are a few examples of thermosetting resins.

　　其中，環氧樹脂或環氧樹脂是當今結構和特殊復合材料應用中常見和廣泛使用的熱固性材料之一。由于它們的高強度和剛性(因為高度的交聯)。環氧樹脂熱固性樹脂幾乎適用于任何用途。
