Liquid reactive adhesive - Stationary reactive adhesive

… Adhesives are classified into several categories according to the method of giving them fluidity during use. The main types are: (1) solution-type adhesives in which rubber or acetyl cellulose is dissolved in a mixture of organic solvents; (2) aqueous-type adhesives in which a solution is dissolved in water, such as the traditional starch paste and glue; (3) emulsion-type adhesives in which a water-insoluble polymer, such as vinyl acetate, is mixed with water in a colloidal form and suspended; (4) liquid reaction-type adhesives that are initially low-molecular-weight or low-molecular-weight polymers and have fluidity, such as many thermosetting resins; and (5) hot-melt-type adhesives that utilize the thermoplasticity of linear polymer copolymers, such as ethylene-vinyl acetate copolymers, which are solid at room temperature but soften at 80-110°C and become fluid enough for bonding when heated to 160-180°C. Technological progress in this field is currently remarkable. …

Japanese:

… 接着剤は作業時に流動性をもたせる方法その他によっていくつかに分類される。そのおもなものをあげると,(1)ゴムあるいはアセチルセルロースなどを有機溶剤の混合物に溶かした溶液型接着剤,(2)溶液のなかでも,古くからのデンプンのり(糊)やにかわ(膠)のように水に溶かした水溶液型接着剤,(3)酢酸ビニルのような水に溶けない高分子がコロイド状に水と混合して懸濁しているエマルジョン型接着剤,(4)多くの熱硬化性樹脂のように,はじめ低分子あるいは低分子量の重合物で流動性をもつ液状反応型接着剤,(5)常温では固体であるが,80~110℃で軟化し,160~180℃に温度を上げると接着に十分な流動性をもつようになる線状高分子の共重合物,たとえばエチレン酢酸ビニル共重合物のようなものの熱可塑性を利用するホットメルト型接着剤などに分けられる。 この分野の技術的進歩は現在著しい。…
