    摘要: The topic of this invention is an intumescent fire retardant and a method for its manufacture. The application of modifiers in the form of so-called “nano-particles” in intumescent systems improves the efficiency fire retardancy and the effectiveness of the system's thermal insulation. The high dispersion of particles influences the decomposition of intumescent systems and the combustion process. Therefore, the structure and thermal resistance of the carbon layer formed are improved.

    摘要: 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.

    摘要: 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.
