HYDROPHILIC COMPOSITION, HYDROPHILIC MEMBER, FIN MATERIAL, HEAT EXCHANGER, AND AIR CONDITIONER

摘要

Disclosed is a hydrophilic composition for forming hydrophilic films that have high thermal diffusivity and are superior from the viewpoints of hydrophilicity, water resistance, and contamination resistance. The hydrophilic composition contains a hydrophilic polymer that includes a hydrolyzable silyl group, said composition being characterized in that the difference between the time it takes the temperature of a hydrophilic member with a hydrophilic film formed on a base material using said hydrophilic composition, as measured by the laser-flash method, to reach half the maximum attainable temperature and the time it takes the temperature of said base material, as measured by the laser-flash method, to reach half the maximum attainable temperature is 0.01 milliseconds or less.
