Abstract:
1. A coating composition comprising: magnesium powder; and a silane modified epoxy isocyanate hybrid polymer or prepolymer, wherein (a) said magnesium powder comprises a mixture of a first magnesium particle powder and a second magnesium particle powder, wherein the first magnesium particle powder and a second magnesium particle powder have substantially different mean particle size distributions, wherein the mixture's bulk density is greater than that of the first magnesium particle powder's bulk density, wherein the mixture's bulk density is greater than that of the second magnesium particle powder's bulk density, and wherein the first magnesium particle powder has a mean particle size distribution of from about 25 μm to about 35 μm and wherein the second magnesium particle powder has a mean particle size distribution of from about 65 μm to about 75 μm; or wherein (b) said silane modified epoxy isocyanate hybrid polymer or prepolymer comprises a polyisocyanate prepolymer, an epoxy prepolymer, and a silanated tetrahydroquinoxalinol crosslinker or a polymerization product thereof.
