Abstract:

Coatings based on ZnO, dimethyl hydrogen phosphite, and ethyl acid phosphate were resistant to outdoor weathering for 6 months. The thickness of the coating, the amount of ethyl acid phosphate in the coating, and the relative humidity of the cring atmosphere affect the properties of the coating. The interactions among these variables are not yet fully understood, and still other variables not yet studed, may also be responsble for some differences in coating properties. Coatings made with MgO were resistant to a temperature of 1000 F, but the coatings were soft. Coatings made with hydrated Al2O3, Li2TiO3, Li2ZO3 failed when heated to 1000 F and mixtures of Bi2O3 or hydrated Al2O3 with H3PO4 did not cure to dry coatings. Author
