CONCLUSIONS There is some correlation, although not precise, of the results between the three types of water test as to their deleterious effects on nitrogen resin-containing alkyd coatings. Composition of the nitrogen resin influences the results markedly. The urea resin is much poorer for resisting water exposure than is the melamine or triazine resin. Some improvement can be obtained by altering the composition of the urea resin, but ...
