Corrosion-inhibiting pigment and paint composition |
摘要 |
The invention relates to a corrosion-inhibiting active pigment for use in the surface protection of iron and iron alloys. The pigment consists of a mixture of calcium hydrogen phosphate dihydrate, magnesium hydrogen phosphate trihydrate and zinc oxide. More specifically, the mixture contains 2 to 98 weight % of ZnO and 98 to 2 weight % of phosphate components. These in turn contain 3 to 97 weight % of CaHPO4x2 H2O and 97 to 3 weight % of MgHPO4x3 H2O. The active pigment is suitable for use in painting compositions or lacquers.
