Document Type and Number:
Japanese Patent JP3379190
Kind Code:
B2
Abstract:
PURPOSE:To obtain a surface coated material useful for a fine material for a heat exchanger, etc., capable of preventing adhesion of waterdrop and reducing pressure loss as much as possible by providing the surface of a substrate with a hydrophilic coating film having fine unevenness. CONSTITUTION:The surface of a substrate such as a metal useful as a heat exchange member for a heat exchanger is provided with a coating film comprising (i) 0.3-5 pts.wt. of a poly(meth)acrylic acid, (ii) 0.3-3 pts.wt. of a cellulosic polymer, (iii) 1-7 pts.wt. of a polyphosphoric acid-based compound, (iv) 0.3-3 pts.wt. of a cross-linking agent, (v) 0-5 pts.wt. of a water-soluble organic polymer except the above-mentioned compounds and (vi) 0-3 pts.wt. of a surfactant as constituent elements and a hydrophilic coating film having fine unevenness on the surface is formed on the coated surface in such a way that >=100 fine particles having 0.1-1mum diameters exist in a visual field of a regular square having 10mum side in a mutually noncontact state or in a wholly or partially bonded or contact state to give the objective surface coated material.
