Title (EN) POLYURETHANE RESIN COMPOSITION AND SEALED OBJECT
(FR) COMPOSITION DE RÉSINE DE POLYURÉTHANE ET OBJET SCELLÉ
(JA) ポリウレタン樹脂組成物および封止物
Abstract:
(EN) Some polyurethane resin compositions are used to seal objects such as electric and electronic components in order to provide protection from condensation and pollutants. Such polyurethane resin compositions are often used under high-temperature environments. Thus, the present invention provides a polyurethane resin composition that has high thermal resistance. The polyurethane resin composition is obtained by reacting a hydroxyl group-containing compound (A) with an isocyanate group-containing compound (B) and contains an anti-oxidant (C) having an alkylthio group.
(FR) Certaines compositions de résine de polyuréthane sont utilisées pour sceller des objets tels que des composants électriques et électroniques afin de les protéger contre la condensation et les polluants. De telles compositions de résine de polyuréthane sont souvent utilisées dans des environnements à haute température. Ainsi, la présente invention concerne une composition de résine de polyuréthane qui présente une résistance thermique élevée. La composition de résine de polyuréthane est obtenue par réaction d'un composé contenant un groupe hydroxy (A) avec un composé contenant un groupe isocyanate (B), et contient un antioxydant (C) comportant un groupe alkylthio.
(JA) 結露や汚染から保護するために、ポリウレタン樹脂組成物を用いて電気電子部品等の対象物を封止することが行われている。このようなポリウレタン樹脂組成物は、高温環境下で使用されることも多い。そこで、高い耐熱性を有するポリウレタン樹脂組成物を提供する。 ポリウレタン樹脂組成物は、水酸基含有化合物(A)とイソシアネート基含有化合物(B)とを反応させることにより得られるポリウレタン樹脂組成物であって、アルキルチオ基を有する酸化防止剤(C)を含む。
