Claim 1
Independent Claim
151 words
A COATING AND BONDING COMPOSITION CONSISTING ESSENTIALLY OF A DISPERSION OF INORGANIC SOLID PARTICULATE MATERIAL HAVING A GRAIN SIZE LESS THAN 325 MESH IN AN AQUEOUS SOLUTION THE SOLUTE OF WHICH CONSISTS ESSENTIALLY OF A COMBINATION OF INORGANIC COMPOUNDS FROM THE GROUP CONSISTING OF PHOSPHORIC ACID, CHROMIC ACID, MOLYBDIC ACID AND THE METAL SALTS OF SAID ACIDS, THE COMBINATION OF COMPOUNDS IN SAID SOLUTION BEING SUCH AS WILL PROVIDE AT LEAST 1 MOL PER LITER DISSOLVED PHOSPHATE, AT LEAST .3 MOL PER LITTER DISSOLVED MATERIAL FROM THE GROUP CONSISTING OF CHROMATE AND MOLYBDATE, AND AT LEAST .5 MOL PER LITER DISSOLVED METAL, SAID SOLID PARTICULATE MATERIAL BEING SUBSTANTIALLY INSOLUBLE IN SAID SOLUTION AND BEING PRESENT IN AN AMOUNT OF FROM ABOUT 10 TO 2000 GRAMS PER LITER OF SAID SOLUTION, SAID COMPOSITION BEING HEAT CURABLE UPON DRYING THEREOF TO A SUBSTANTIALLY WATER-INSOLUBLE MATERIAL WITH SAID SOLID PARTICULATE MATERIAL BEING BONDED THEREIN.

A COATING AND BONDING COMPOSITION CONSISTING ESSENTIALLY OF A DISPERSION OF INORGANIC SOLID PARTICULATE MATERIAL HAVING A GRAIN SIZE LESS THAN 325 MESH IN AN AQUEOUS SOLUTION THE SOLUTE OF WHICH CONSISTS ESSENTIALLY OF A COMBINATION OF INORGANIC COMPOUNDS FROM THE GROUP CONSISTING OF PHOSPHORIC ACID, CHROMIC ACID, MOLYBDIC ACID AND THE METAL SALTS OF SAID ACIDS, THE COMBINATION OF COMPOUNDS IN SAID SOLUTION BEING SUCH AS WILL PROVIDE AT LEAST 1 MOL PER LITER DISSOLVED PHOSPHATE, AT LEAST .3 MOL PER LITTER DISSOLVED MATERIAL FROM THE GROUP CONSISTING OF CHROMATE AND MOLYBDATE, AND AT LEAST .5 MOL PER LITER DISSOLVED METAL, SAID SOLID PARTICULATE MATERIAL BEING SUBSTANTIALLY INSOLUBLE IN SAID SOLUTION AND BEING PRESENT IN AN AMOUNT OF FROM ABOUT 10 TO 2000 GRAMS PER LITER OF SAID SOLUTION, SAID COMPOSITION BEING HEAT CURABLE UPON DRYING THEREOF TO A SUBSTANTIALLY WATER-INSOLUBLE MATERIAL WITH SAID SOLID PARTICULATE MATERIAL BEING BONDED THEREIN.
Claim 3
Independent Claim
185 words
A METHOD FOR COATING A SURFACE COMPRISING THE STEPS OF APPLYING TO THE SURFACE A COMPOSITION CONSISTING ESSENTIALLY OF A UNIFORM MIXTURE OF INORGANIC SOLID PARTICULATE MATERIAL HAVING A GRAIN SIZE LESS THAN 325 MESH IN AN AQUEOUS SOLUTION THE SOLUTE OF WHICH CONSISTS ESSENTIALLY OF A COMBINATION OF INORGANIC COMPOUNDS FROM THE GROUP CONSISTING OF PHOSPHORIC ACID, CHROMIC ACID, MOLYBDIC ACID AND THE METAL SALTS OF SAID ACIDS, THE COMBINATION OF COMPOUNDS IN SAID SOLUTION BEING SUCH AS WILL PROVIDE ABOUT FROM 1 TO 4 MOLS PER LITTER DISSOLVED PHOSPHATE, FROM .5 TO 3 MOLS PER LITTER DISSOLVED MATERIAL FROM THE GROUP CONSISTING OF CHROMATE AND MOLYBDATE, AND FROM 1.5 TO 4 MOLS PER LITTER DISSOLVED METAL, SAID SOLID PARTICULATE MATERIAL BEING SUBSTANTIALLY INSOLUBLE IN SAID SOLUTION AND BEING PRESENT IN AN AMOUNT OF FROM ABOUT 10 TO 2000 GRAMS PER LITER OF SAID SOLUTION; DRYING SAID COMPOSITION; AND THEN CURING SAID COMPOSITION BY HEATING TO A TEMPERATURE OF AT LEAST ABOUT 500*F. FOR A TIME SUFFICIENT TO CAUSE SAID COMPOSITION TO BECOME INSOLUBLE IN WATER WITH SAID SOLID PARTICULATE MATERIAL BEING BONDED THEREIN.
