Abstract
Official abstract text for this publication.
A coating material is allowed to contain a sulfate having a higher degree of solubility in water than that of calcium sulfate. The sulfate is an additive for coating materials which is used for reducing the consumption of zinc (including zinc oxide) in a coating film formed from the coating material and the corrosion of a base material when the coating film is scratched. The content of the sulfate can be 0.004 to 0.65 mol per 100 g of the content of zinc. Alternatively, the content of the sulfate may be 0.006 to 0.186 mol per 100 g of a heating residue (except for the sulfate added) of a coating film.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coating material comprising: a zinc powder; a binder; and a sulfate having a higher degree of solubility in water than an eighth of a degree of solubility in water of calcium sulfate, and wherein a content of the sulfate is 0.004 to 0.065 mol per 100 g of a content of zinc in the coating material. 2. The coating material according to claim 1 , wherein the zinc powder is a powder of zinc alloy comprising zinc and at least one of aluminum or magnesium. 3. The coating material according to claim 1 , wherein the sulfate is at least one of potassium sulfate, sodium sulfate, magnesium sulfate, calcium sulfate, ferric sulfate, ferrous sulfate, lithium sulfate, or aluminum sulfate. 4. The coating material according to claim 1 , wherein the binder is water-soluble. 5. The coating material according to claim 1 , wherein the binder is dispersible in water. 6. A coating material comprising: a zinc powder; a binder; and a sulfate having a higher degree of solubility in water than an eighth of a degree of solubility in water of calcium sulfate, wherein a content of the sulfate is 0.006 to 0.186 mol per 100 g of a heating residue of a coating film, wherein the heating residue excludes the sulfate added. 7. The coating material according to claim 6 , wherein the zinc powder is a powder of zinc alloy comprising zinc and at least one of aluminum or magnesium. 8. The coating material according to claim 6 , wherein the sulfate is at least one of potassium sulfate, sodium sulfate, magnesium sulfate, calcium sulfate, ferric sulfate, ferrous sulfate, lithium sulfate, or aluminum sulfate. 9. The coating material according to claim 6 , wherein the binder is water-soluble. 10. The coating material according to claim 6 , wherein the binder is dispersible in water. 11. A coating material comprising: a binder; and a sulfate having a higher degree of solubility in water than an eighth of a degree of solubility in water of calcium sulfate, wherein a content of the sulfate is 0.006 to 0.186 mol per 100 g of a heating residue of a coating film, and wherein the heating residue excludes the sulfate added. 12. The coating material according to claim 11 further comprising zinc powder. 13. The coating material according to claim 11 , wherein the sulfate is at least one of potassium sulfate, sodium sulfate, magnesium sulfate, calcium sulfate, ferric sulfate, ferrous sulfate, lithium sulfate, or aluminum sulfate. 14. The coating material according to claim 11 , wherein the binder is water-soluble. 15. The coating material according to claim 11 , wherein the binder is dispersible in water.
