## Abstract

A corrosion inhibition composition is disclosed comprising a zinc oxide, a zinc phosphate, a calcium silicate, an aluminum phosphate, a zinc calcium strontium aluminum orthophosphate silicate hydrate, a molybdate compound, a silicate compound, and a zinc phthalate compound.

## Claims

### Claim 1

A method of disposing a corrosion resistant coating to a substrate, comprising:
forming the corrosion resistant coating by combining a corrosion inhibition composition and an application vehicle; and
applying the corrosion resistant coating to the substrate,
wherein the corrosion inhibition composition comprises a zinc oxide, a zinc phosphate, a calcium silicate, an aluminum phosphate, a zinc calcium strontium aluminum orthophosphate silicate hydrate, a molybdate compound, a silicate compound, and a zinc phthalate compound.

### Claim 2 (depends on 1)

The method of claim 1, wherein the zinc phthalate compound comprises at least one of a nitrophthalate zinc salt or a phthalic acid zinc salt.
