ABSTRACT:
The combination of an ethylene/acrylic acid copolymer and a water soluble amine salt of a fatty acid is useful as a hydrophilic coating for the surfaces of fins in a heat exchanger. The exchanger is more efficient because the coating prevents the blockage of air flow by beads of condensed water which would otherwise build up in the narrow spaces between the fins.
