Water resistant aluminum particles and coating

Claim 1

A composition characterized by comprising metal particles which include compound of the formulae of Figures lA, 1B or lC in an effective concentration to retard the reaction of the metal with water, thereby inhibiting the evolution of hydrogen gas, where in said formulae, and where Z is hydrogen or means for neutralizing acid phosphate; and where R is benzo, a halo group, an alkyl group having from 1 to 24 carbon atoms, a cycloalkyl group having from 3 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a halo substituted aryl group wherein said aryl has from 6 to 40 carbon atoms, an alpha or beta naphthyl, a halo substituted alpha or beta naphthyl, a 3 to 20 carbon atom cycloalkyl substituted alpha or beta naphthyl, an alpha or beta alkyl substituted naphthyl wherein said alkyl has from 1 to 24 carbon atoms, or a heterosubstituent substituted aryl wherein said aryl has from 6 to 40 carbon atoms, and said heterosubstituent consists of CN, N0 2 , COOH, CHO, OH, a pyridinyl, an alpha or beta furyl, or an alpha or beta thienyl, and, if desired, further comprising a compatible liquid and a surfactant.

Claim 6

A method characterized by comprising contacting metal particles with compound of the formulae of Figures lA, 1B or 1C in an effective concentration to retard the reaction of the metal with water, thereby inhibiting the evolution of hydrogen gas, where in said formulae, and where Z is hydrogen or means for neutralizing acid phosphate; and where R is benzo, a halo group, an alkyl group having from 1 to 24 carbon atoms, a cycloakyl group having from 3 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a halo substituted aryl group wherein said aryl has from 6 to 40 carbon atoms, an alpha or beta naphthyl, a halo substituted alpha or beta naphthyl, a 3 to 20 carbon atom cycloalkyl substituted alpha or beta naphthyl, an alpha or beta alkyl substituted naphthyl wherein said alkyl has from 1 to 24 carbon atoms, or a heterosubstituent substituted aryl wherein said aryl has from 6 to 40 carbon atoms, and said heterosubstituent consists of CN, N0 2 , COOH, CHO, OH, a pyridinyl, an alpha or beta furyl, or an alpha or beta thienyl.

Claim 7

A method characterized by comprising contacting metal particles with compound of the formulae of Figures lA, 1B or 1C in an effective concentration to retard the reaction of the metal with water, thereby inhibiting the evolution of hydrogen gas, where in said formulae, and where Z is hydrogen or means for neutralizing acid phosphate; and where R is benzo, a halo group, an alkyl group having from 1 to 24 carbon atoms, a cycloakyl group having from 3 to 20 carbon atoms, an aryl group having from 6 to 40 carbon atoms, a halo substituted aryl group wherein said aryl has from 6 to 40 carbon atoms, an alpha or beta naphthyl, a halo substituted alpha or beta naphthyl, a 3 to 20 carbon atom cycloalkyl substituted alpha or beta naphthyl, an alpha or beta alkyl substituted naphthyl wherein said alkyl has from 1 to 24 carbon atoms, or a heterosubstituent substituted aryl wherein said aryl has from 6 to 40 carbon atoms, and said heterosubstituent consists of CN, N0 2 , COOH, CHO, OH, a pyridinyl, an alpha or beta furyl, or an alpha or beta thienyl.
