    • Provided is a precoated fin material for heat exchangers that allows the construction of a fin structure in which frost formation at the time of heater operation can be prevented to the extent possible, and under such a condition that condensation is liable to occur on a fin surface, a water droplet of condensed water can be quickly removed by bringing the water droplet into contact with a hydrophilic film, and as a result, a favorable heat exchange function can be maintained without any increase in ventilation resistance. Also provided is a heat exchanger including such fin structure. The precoated fin material for heat exchangers includes: a fin substrate formed of an aluminum plate material; a crosslinked hydrophobic film having a frost formation-suppressing effect, the crosslinked hydrophobic film being formed on one surface of the fin substrate and being formed of an aqueous hydrophobic coating composition containing a resin (A) having a fluorine atom-containing group, a quaternary ammonium salt group-containing modified epoxy resin (B), and an amino resin (C) at predetermined ratios; and a hydrophilic film having a condensed water-removing effect, the hydrophilic film being formed on another surface of the fin substrate. The heat exchanger includes a fin structure in which a hydrophobic surface having a frost formation-suppressing effect and a hydrophilic surface having a condensed water-removing effect are opposite to each other.
    • 提供一种用于热交换器的预涂布翅片材料,其允许构造翅片结构,其中可以在可能的程度上防止加热器操作时的结霜,并且在翅片表面上容易发生冷凝的条件下 通过使水滴与亲水膜接触,可以快速除去冷凝水的水滴,结果,可以保持良好的热交换功能而不会增加通气阻力。 还提供了包括这种翅片结构的热交换器。 用于热交换器的预涂布翅片材料包括:由铝板材料形成的散热片基板; 具有霜冻抑制效果的交联的疏水性膜,所述交联疏水性膜形成在所述散热片基板的一个表面上,并且由含有含氟原子的基团的树脂(A),含有氟原子的基团的四氢呋喃 含铵盐基团的改性环氧树脂(B)和氨基树脂(C); 以及具有冷凝除水效果的亲水性膜,所述亲水膜形成在散热片基板的另一表面上。 热交换器包括翅片结构,其中具有霜冻抑制效果的疏水性表面和具有冷凝除水效果的亲水性表面彼此相反。

    • The present invention is directed to an optically clear coating made from a composition comprising an epoxy-melamine resin. The coating is obtained on a metallic substrate and has a very rigid structure and a unique combination of properties that includes hydrophobicity/easy-to-clean, adhesion to bright chrome, abrasion resistance and chemical resistance. The coating composition comprises (A) a mixture of at least one hydrolysable silane and one hydrolysable metal compound, the compounds of said mixture being partly or fully hydrolyzed and partly or fully condensed, (B) at least one melamine derivative selected from derivatives having formula (C3N3)(NR4R5)3, and derivatives having formula (C3N3)(NR4R5)3-p(NR4R6)p, wherein R4 and R5 are independently selected from H, hydroxymethylene and alkoxymethylene, with the proviso that at least one of the R4 groups is a hydroxymethylene or alkoxymethylene group, and R6 is —CH2—NR4(C3N3)(NR4R5)2 or —CH2—O—CH2-NR4(C3N3)(NR4R5)2, and p is 1 or 2, and either at least one partially or fully fluorinated, at least partly hydrolyzed and condensed silane compound, this compound being part of the said mixture (A) of hydrolysable silanes, or (C) at least one partially or fully fluorinated organic compound containing at least one group which may bind to hydroxy groups.
