  • Patent number: 4505748
    Abstract: An anti-corrosive coating composition includes an anti-corrosive pigment component comprising (a) a salt comprising a polyvalent metal cation and an organic polyphosphonic acid containing at least 2 phosphonic acid groups and (b) a corrosion passivator capable of modifying the metal oxide film on the metal to be protected to render it more protective. The ratio of the polyphosphonate salt (a) to the passivator (b) in the coating composition is 1:1 to 50:1 by weight.

  • Patent number: 4444930
    Abstract: The invention relates to a fire-resistant synthetic resin composition containing a polycarbonate, more specifically a bisphenol A derivative, a phosphorous fireproofing additive derived from phosphonic acid, and possibly other additives and/or fillers.The fireproofing additive is a Li, Na or K hemiester of a phosphonic acid derived from an aromatic or cycloaliphatic hydrocarbon, or from a polynuclear aromatic compound, and is added at the rate of 0.01 to 0.4 weight % in relation to polycarbonate. This small amount of additive improves the fire-resistant properties of the polycarbonate, without affecting its mechanical properties.
