THE DEVELOPMENT OF HEAT-RESISTANT PAINTS FOR METALS
Abstract
Research continued on the ZnO-dimethyl hydrogen phosphite (DMHP)-ethyl acid phosphate (EAP) coating system. The relative humidity and temperature during curing were important in developing certain properties in these coatings. The methods of preparing and applying these coating compositions had a minor influence on coating properties. Addition of water improved some coating properties but impaired others; additions of various metal oxides or a colloidal SiO2 dispersion did not improve coating properties. The study of frits in phosphorus-bonded coatings showed that relative humidity and temperature during curing were important. Benefits were indicated for the inclusion of BaO in a glassy matrix. Coatings prepared from the zirconates or titanates of Ba or Zn and organo-P compounds were heat resistant, but were deficient in hardness and in water resistance. The reaction for forming ZnO-DMHP-EAP coatings was mainly dependent on the activity of the phosphite. (Author)
