接着剤は耐熱性、耐薬品性に乏しく、広範囲の使用途に
は不向きである。Until now, urethane adhesives have been used for potting hollow fiber membrane modules. This urethane adhesive has poor heat resistance and chemical resistance, and is not suitable for a wide range of uses.
【００１２】そのため、ポッティング剤としてより耐薬
品性、耐熱性を有するエポキシ接着剤を用いることとし
た。Therefore, an epoxy adhesive having more chemical resistance and heat resistance is used as the potting agent.
