Patent ID: 8524816

Claim:
A coating composition comprising a solids phase comprising: (a) a primary resin and a blocked isocyanate, and (b) a first bio-diesel fuel degradation product neutralizing agent comprising at least one of phosphate compounds, citrates, borates, glycine compounds, carbonates, hydroxides, acetate compounds, urea compounds, ammonia, ammonia compounds, ethanesulfonic acid compounds, propanesulfonic acid compounds or amine compounds, and further comprising a second bio-diesel fuel degradation product neutralizing agent comprising a peroxide or hydro-peroxide neutralizing, decomposing or scavenging material, wherein the coating composition is formulated so that when cured the cured coating has a resistance to corrosion by bio-diesel fuel wherein the first bio-diesel fuel degradation product neutralizing agent is present in about 0.5 to about 40.0 wt % of the solids phase, wherein the second bio-diesel fuel degradation product neutralizing agent is present in about 0.25 to about 30.0 wt % of the solids phase, further comprising a trimodal size distribution of particles comprising a first group of micron size particles, a second group of submicron particles, and a third group of nanoparticles, or a bimodal particle shape distribution comprising a first group of particles having a platelet or near-platelet shape and a second group of particles having a spherical or near-spherical shape and an iron based pigment.
