    Abstract: This invention concerns a process for imparting corrosion and creep resistance to a coating prepared from a particulate polymer composition and applied from a fluidized bed or by electrostatic spraying over metal substrates. The process of the present invention provides for maintaining the content of acid functionality of an acid-functionalized semicrystalline or acid-functionalized amorphous particulate polymer of the particulate polymer composition within a desired range. The acid functionality on the particulate polymer can be maintained, by crosslinking and/or neutralizing, within a desired range of the acid content which results in imparting corrosion and creep resistance to the coating applied over the metal substrates. Neutralizing the acid functionality of the polymer component results in hardening the coatings resulting therefrom. The process further provides for adding anticorrosive pigments to the composition for further improving corrosion resistance of the resultant coatings.

    Abstract: The present invention provides a coating composition for hydrophilization comprising (A) a water-soluble or water-dispersible organic resin, (B) organic resin fine particles described below and (C) a crosslinking agent, and a method for hydrophilization of heat exchanger fins by coating said fins with the above composition. The organic resin fine particles (B) are fine particles having a weight-average particle diameter/number-average particle diameter ratio of 1.2 or less and an average primary particle diameter of 0.1-1.0 .mu.m, which are obtained by dispersion-polymerizing 100 parts by weight of a monomer mixture consisting of 0.1-10.0% by weight of (a) at least one monomer selected from a polyoxyalkylene chain-containing (meth)acrylate and a (meth)acrylamide, 15.0-45.0% by weight of (b) divinylbenzene, 45.0-84.9% by weight of (c) styrene and 0-39.9% by weight of (d) (meth)acrylic acid, in the presence of 40 parts by weight of a poly(meth)acrylic acid in a lower alcohol. The composition can form a hydrophilic film superior in retention of hydrophilicity, continuous formability and corrosion resistance.
