Coating resistant to bio-diesel fuels

A product comprising:

• a substrate and a cured coating over the substrate, the cured coating comprising (a) the reaction product of a primary resin and a blocked isocyanate, and (b) a first bio-diesel fuel degradation product neutralizing agent comprising at least one of citrates, borates, glycine compounds, carbonates, hydroxides, acetate compounds, urea compounds, ammonia, ammonia compounds, ethanesulfonic acid compounds, or propanesulfonic acid compounds, and wherein the substrate is shaped and welded into a bio-diesel fuel tank with the cured coating facing the cavity of the tank, and further comprising a second bio-diesel fuel degradation product neutralizing agent comprising a peroxide or hydroperoxide neutralizing, decomposing or scavenging material.

A product comprising:

• a substrate and a cured coating over the substrate wherein the substrate is shaped and welded into a bio-diesel fuel tank with the cured coating facing the cavity of the tank, wherein the substrate comprises a first shell and a second shell, and wherein the first shell comprises a first flange, and wherein the second shell comprises a second flange, and wherein the first flange is welded to the second flange, the cured coating comprising (a) the reaction product of a phenoxy resin, polyvinyl butyral, and a methylethylketoxime blocked toluene diisocyanate, and (b) the cured coating further comprising a pH buffer comprising at least one of barium borate or barium metaborate, a bio-diesel degradation product neutralizing agent comprising di-lauryl-3,3′-thiodipropionate, electrically conductive particles comprising at least one of FeP or Fe2P, and a trimodal size distribution of barrier particles comprising talc platelets, mica platelets, barium sulfate, and alumina, the cured coating being formulated to be resistant to corrosion by bio-diesel fuels.

A coating composition comprising:

• a phenoxy resin, polyvinyl butyral, a methylethylketoxime blocked toluene diisocyanate, a pH buffer comprising at least one of barium borate or barium metaborate, a first bio-diesel fuel degradation product comprising barium and a second bio-diesel fuel degradation product neutralizing agent comprising di-lauryl-3,3′-thiodipropionate, electrically conductive particles comprising at least one of FeP or Fe2P, and a trimodal size distribution of barrier particles comprising talc platelets, mica platelets, barium sulfate, and alumina.

A coating composition comprising:

• a phenoxy resin, polyvinyl butyral, and a blocked isocyanate, and wherein the phenoxy resin has an average molecular weight ranging from about 10,000 to about 100,000, and wherein the polyvinyl butyral has an average molecular weight ranging from about 10,000 to about 350,000, and a barium compound and a sulfur compound.
