Title (EN) POWDER PAINT COMPOSITION
(FR) COMPOSITION DE PEINTURE EN POUDRE
(JA) 粉体塗料組成物
Abstract:
(EN) Provided is a powder paint composition with which it is possible to form a uniform coating that has excellent edge covering properties and excellent insulating properties. In addition, a coating formation method using this paint composition allows for heating at a low temperature. The powder paint composition contains a bisphenol A epoxy resin (A), a phenolic curing agent (B), and a curing accelerator (C) as coating formation components. The bisphenol A epoxy resin (A) has an epoxy equivalent weight of 800 g/eq to 1,150 g/eq and a softening point of 90ºC to 115ºC. The phenolic curing agent (B) has a phenolic hydroxyl group equivalent weight of 200 g/eq to 750 g/eq. The powder paint composition has a gel time at 200ºC of 10 seconds to 25 seconds.
(FR) L'invention concerne une composition de peinture en poudre permettant de former un revêtement uniforme qui présente d'excellentes propriétés de recouvrement de bord et d'excellentes propriétés isolantes. De plus, un procédé de formation de revêtement mettant en œuvre ladite composition de peinture autorise un chauffage à basse température. La composition de peinture en poudre contient une résine époxy de bisphénol A (A), un agent de durcissement phénolique (B) et un accélérateur de durcissement (C) en tant que constituants de formation de revêtement. La résine époxy de bisphénol A (A) présente un poids équivalent époxy de 800 g/éq à 1 150 g/éq et un point de ramollissement de 90 °C à 115 °C. L'agent de durcissement phénolique (B) présente un poids équivalent de groupe hydroxyle phénolique de 200 g/éq à 750 g/éq.La composition de peinture en poudre présente un temps de gélification à 200 °C de 10 secondes à 25 secondes.
(JA) 本発明は、優れたエッジカバー性を有し、均一な塗膜であり、優れた絶縁性を有する塗膜を形成できる粉体塗料組成物を提供する。加えて、本発明に係る塗料組成物を用いる塗膜形成方法であれば、低温で加熱を行うことができる。塗膜形成成分として、ビスフェノールA型エポキシ樹脂(A)と、フェノール系硬化剤(B)と、硬化促進剤(C)とを含む、粉体塗料組成物であって、前記ビスフェノールA型エポキシ樹脂(A)は、800g/eq以上1,150g/eq以下のエポキシ当量、及び90℃以上115℃以下の軟化点を有し、前記フェノール系硬化剤(B)は、フェノール性水酸基当量が200g/eq以上750g/eq以下であり、並びに前記粉体塗料組成物の200℃におけるゲルタイムが10秒以上25秒以下である、粉体塗料組成物。
