Abstract:
(EN) [Problem] To provide a cationic electrodeposition coating composition containing an amine-modified epoxy resin which achieves sufficient throwing power and corrosion resistance even in the case of being less than 1000 μS/cm, and has excellent emulsion stability. [Solution] The cationic electrodeposition coating composition is characterized in that a resin emulsion contains: an amino group-modified epoxy resin (A) obtained by reacting, with an amine compound (A2), an epoxy group of an epoxy resin (A1) obtained by reacting a propylene oxide-added diepoxy resin (a1) having a specific structure, a bisphenol compound (a2), a diepoxy resin (a3), and a dicarboxylic acid (a4) having two carboxyl groups bonded together by at least one carbon atom; and a curing agent (B) which can cross-link the amino group-modified epoxy resin (A).
(FR) [Problème] Fournir une composition de revêtement par électrodéposition cationique contenant une résine époxyde modifiée par une amine qui permette d'obtenir un pouvoir de pénétration et une résistance à la corrosion suffisants même si elle est inférieure à 1000 µS/cm, et qui présente une excellente stabilité d'émulsion. [Solution] La composition de revêtement par électrodéposition cationique est caractérisée en ce qu'une émulsion de résine contient : une résine époxyde modifiée par un groupe amino (A) obtenue en faisant réagir, avec un composé amine (A2), un groupe époxyde d'une résine époxyde (A1) obtenu par réaction d'une résine diépoxyde à oxyde de propylène ajouté (a1) ayant une structure spécifique, d'un composé de bisphénol (a2), d'une résine diépoxyde (a3) et d'un acide dicarboxylique (a4) ayant deux groupes carboxyle liés ensemble par au moins un atome de carbone ; et un agent de durcissement (B) qui peut réticuler résine époxyde modifiée par le groupe amino (A).
(JA) 【課題】 1000μS/cm未満でも十分な付き廻り性及び耐食性を実現でき、且つ、優れたエマルション安定性を有する当該アミン変性エポキシ樹脂を含有するカチオン電着塗料組成物の提供 【解決手段】 樹脂エマルションが、特定構造のプロピレンオキサイド付加ジエポキシ樹脂(a1)とビスフェノール化合物(a2)とジエポキシ樹脂(a3)と2つのカルボキシル基が少なくとも1個の炭素原子を介して結合されているジカルボン酸(a4)とを反応させてなるエポキシ樹脂(A1)のエポキシ基に対してアミン化合物(A2)を反応させて得られるアミノ基変性エポキシ樹脂(A)と、(A)を架橋し得る硬化剤(B)とを含むことを特徴とするカチオン電着塗料組成物
