Abstract
A coating composition which is capable of being used effectively in a wide variety of applications where heretofore known coating compositions could not be used, or where their use was accompanied by various disadvantages is disclosed. The curing temperature at which coatings (for example, corrosion resistant coatings) are formed from an aqueous coating composition containing dissolved phosphate, dissolved dichromate, dissolved aluminum, and solid particulate material is lowered by adding diethanolamine to the composition. The coating composition of the present invention can be used to effectively coat substrates which heretofore could not be coated or could not be coated satisfactorily as a result of the substrate being destroyed or degraded by the relatively high temperatures that were required to satisfactorily cure heretofore known coating compositions.
