As the protective mechanism of an organic coating is largely dependent on its polymer used as binder, blending of polymers has long been practised to improve end use properties. Polymer alloys, in particular interpenetrating polymer networks (IPNs), offer a variety of improved coating properties. IPNs represent a mode of blending of two or more polymers to produce a mixture in which the phase seperation is not as extensive as in polymer blends. The combination of varied chemical types of polymeric networks in different proportions, often resulting in different controlled morphologies, has produced IPNs with stnergistic behavior. The physical properties of the IPNs fall into two classes: The first class contains those properties, which vary monotonously as the composition is varied from one pure network to the other. The second class of properties includes those which atleast in certain IPNs can exhibit maxima or minima at an intermediate composition between the two networks. IPNs offer a broad range of applications including protective coatings. IPN technology has surprisingly covered almost all sorts of applications and, in the coatings area also, quite a good number of commercial products based on full, semi- and pseudo-IPNs are already available in the market, although they are rarely identified as such. In this paper the noteworthy IPNs so far published have been cited
