A method of applying a water-borne lacquer to a non-ferrous metal product

摘要

A method of applying a water-borne lacquer containing 75 to 80 % by weight of acrylic dispersions, 4.75 to 5.75 % by weight of additives for wetting, dispersion and non-foaming, 0.1 to 0.2 % by weight of corrosion inhibitor, 2 to 10 % by weight of water-soluble organic corrosion inhibitor based on a mixture of potassium octadecanoate, tripotassium phosphate and 2,2,2'-nitroloethanol, 5 to 10 % by weight of an anticorrosive pigment based on the oxyaminophosphate complex of calcium and manganese; and water for the non-ferrous metal product is based on the fact that varnish diluted by 8 to 18 % by weight is applied by pneumatic spraying at a pressure of 0.15 to 0.45 MPa at room temperature of 18 to 23 ° C and relative air humidity max. 80% to the surface of the non-ferrous metal product at room temperature between 18 and 23 °C with a min. 3 °C above the dew point, after applying the lacquer drying at room temperature from 18 to 23 °C.
