Beschreibung
Zusammenfassung:	A pre-coated fin material (1) has a substrate (2) and a resin coating (3) provided on the substrate (2). The mass per unit area of the resin coating (3) is at least 0.2 g/m2 and at most 2.5 g/m2. The pre-coated fin material (1) has the following properties: from when measuring begins until one hour has passed, the average value of the spontaneous potential measured in a 5 mass% NaCl aqueous solution that has a pH of 3 is at least +0.040 V and at most +0.2 V relative to the average value of the spontaneous potential of the substrate (2); and the angle of contact with water after being submerged in flowing water for 10 minutes is at least 20° and at most 40°. L'invention concerne un matériau préenduit (1) pour ailettes, qui comprend un substrat (2) et un revêtement résineux (3) appliqué sur le substrat (2). La masse surfacique du revêtement résineux (3) est d'au moins 0,2 g/m2 et d'au plus 2,5 g/m2. Le matériau préenduit (1) pour ailettes présente les propriétés suivantes : à partir du moment où la mesure commence jusqu'à ce qu'une heure se soit écoulée, la valeur moyenne du potentiel spontané mesuré dans une solution aqueuse à 5 % en masse de NaCl qui a un pH de 3 est d'au moins +0 040 V et d'au plus +0,2 V par rapport à la valeur moyenne du potentiel spontané du substrat (2) ; et l'angle de contact avec l'eau après avoir été immergé dans de l'eau en écoulement pendant 10 minutes est d'au moins 20° et d'au plus 40°. プレコートフィン材（１）は、基材（２）と、基材（２）上に設けられた樹脂皮膜（３）とを有している。樹脂皮膜（３）の単位面積当たりの質量は０．２ｇ／ｍ２以上２．５ｇ／ｍ２以下である。プレコートフィン材（１）は、ｐＨ３の５質量％ＮａＣｌ水溶液中で測定した自然電位の測定開始時点から１時間経過時点までの平均値が、基材（２）の自然電位の平均値に対して＋０．０４０Ｖ以上＋０．２Ｖ以下となり、流水に１０分間浸漬した後の水の接触角が２０°以上４０°以下となる特性を有している。
