Title:
HYDROPHILIC-FILM-FORMING COATING AGENT AND HEAT EXCHANGER MEMBER COATED THEREWITH
Document Type and Number:
Japanese Patent JP3158989
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a hydrophilic-film-forming coating agent improved in hydrophilicity, water-film-forming properties, and prevention of water drop formation by using as the essential components a polymer compd. having an amide group is the molecule, a polymer compd. having an ether bond in the molecule, and a polymer compd. having at least two aldehyde groups in the molecule.
SOLUTION: This agent comprises 0.5-5wt.% polymer compd. having an amide group, 1-10wt.% polymer having an ether bond in the molecule, 0.2-2wt.% polymer compd. having at least two aldehyde groups, if necessary 0.8-3.0wt.% water-sol. polymer compd. other than foregoing compds., 0.1-1.0wt.% surfactant, and the rest being water. The surface of a heat exchanger member is coated with the agent and baked.
