<p>Anti-corrosion pigments based on zinc silicate, produced from 35-65% by weight of ZnO, 15-35% by weight SiO2, 5-20% per weight B2O3 and 1-20% by weight WO3, which can be completly or partly replaced by MoO3 and/or SnO2, whereby the amount of zinc silicate, boronoxide and the other metal oxides or their hydrates are contained individually or in combination in such a way that the overall combination with the zinc silicate and boronoxide contains at least one of the WO3, MoO3 and/or SnO2 oxides in a quantity which brings the total amount to 100%. The anti-corrosion pigments can be produced by dry mixing of the components, melting for a period of between 1 and 3 hours at 1,100oC - 1,400oC and by grinding to the desired degree of fineness.</p> |
