THE DEVELOPMENT OF HEAT-RESISTANT PAINTS FOR METALS
Abstract
Studies were made of the effects of composition and conditions of application on the properties of heat-resistant paints that were cured at low temperatures by the reaction of organo-phosphorus compounds with metal oxides and ceramic frits. Formulations and coating procedures were developed that could produce coatings on metal substrates with any of the several target properties that were desired, but it was not yet possible to obtain all of these properties simultaneously and reproducibly. The most promising coatings were acid phosphate. A number of metal oxides, ceramic frits, and organo-phosphorus compounds were investigated for use in phosphorus-bonded coatings. The ceramic frits, some metal zirconates, and bis(2-ethylhexyl) phosphite merited further study. Reaction mechanism studies indicated that the dimethyl hydrogen phosphite hydrolyzed and reacted with ZnO to form an amorphous polymeric product that is insoluble in organic solvents. (Author)
