Title:
HYDROPHILIZATION TREATMENT, ALUMINUM-CONTAINING METAL MATERIAL, AND ALUMINUM ALLOY HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2010185024
Kind Code:
A
Abstract:

To provide a hydrophilization treatment for forming a film which imparts excellent moisture condensation wetting properties as well as antibacterial properties on the surface of an aluminum-containing metal material.

This hydrophilization treatment includes a chitosan derivative (component B) produced by adding a compound (component A) having an unsaturated group between the carbon-carbon atoms at the α-position of its electron-drawing group to a part or all of the primary amino groups of chitosan. This hydrophilization treatment forms a film which gives moisture condensation wetting properties as well as antibacterial properties onto the aluminum-containing material of a material to be treated.
