Abstract
A black uniform coating with excellent adhesion, bend flexibility, and cosion resistant characteristics can be formed on metals such as aluminum and its alloys, zinc and its alloys, and copper and its alloys such as brass, with the deposition of zinc and antimony compounds through a base solution and sealed with a water base sealer. The water based sealer comprises an organic film forming resin, an organic solvent, and emulsifying agents and an alkyd resin.
Claims19
A method for forming a black coating on a metallic substrate comprising the steps of:
- a) contacting said substrate with a blackening treatment comprising zinc and antimony;
- b) drying said substrate
- c) contacting said substrate with a sealing treatment comprising an organic film forming resin component, an organic solvent, and lacquer;
- and
- d) drying said substrate to thereby provide a dry, black coating on said substrate.
Method of forming a black coating on a metallic substrate, said method comprising the steps of:
- a) contacting said metallic substrate with a basic blackening treatment solution or dispersion comprising zinc and antimony;
- b) forming a sealing treatment by the steps of:
- i) providing an emulsion including an organic film forming resin component;
- ii) providing a lacquer;
- iii) mixing said emulsion i) and lacquer ii) and adding water to said mixture of i) and ii) to form said sealing treatment,
- c) drying said metallic substrate after said step a);
- and then
- d) contacting said metallic substrate with said sealing treatment;
- and drying said metallic substrate.
