Definitions
- paint is intended to comprise paints, varnishes, lacquers, enamels and similar film forming materials.
- Said method executed in several modes, is suffering from the drawback that the pretreatment of the zinc surface that has been eflioresced after a rather short period already is time consuming. Additionally fully drying the zinc surface while preventing its oxidation is diiiicult if not impossible.
- the paint components of the paint have to be able to resist the temperature the articles have at the time of applying the paint. Applying the paint while the articles are at a temperature of at least 100 C. is advisable in order to prevent oxidation and deterioration of the metal coating to the utmost as well as to protect it from becoming humid while ensuring a suitable drying or baking of the protective coating.
- thermosetting resin-based binding agent the curing properties of which being adapted to the temperature the articles have at the time of applying the paint.
- suitable thermosetting resins being epoxy resins and alkyd resins.
- the paint comprises a binding agent which will become cross-linked within some minutes at the temperature the articles have at the time of applying the paint in order to enable the thus treated articles to become stacked within a practical lapse of time after the protective film has been applied thereto while preventing the risk of seriously damaging said film.
- Steel beams having an H section with a length of 4.5 m., a height of 20 cm. and a material thickness ranging from 7 to 13 mm. were hot galvanized as usual by being pickled and subsequently passed through the usual coating pot containing molten zinc covered with a flux layer and being maintained at a temperature of from 420 to 470 C.
- the zinc coated beams after emerging from the coating bath cooled down and accordingly the zinc coating solidified. After having arrived at a temperature of about 200 C. said beams were sprayed with a paint of the following composition:
- Solvesso (Esso) 20 Ethyl glycolic ether 5
- the paint flowed to an even protective film that quickly dried and became hard. After having further cooled down the beams could become stacked for storage and shipping without running the risk of substantially damaging the protective paint coating.
- the method may be used in combination with continuously hot-dip galvanizing or aluminizing of strip steel.
- step (b) dipping the metal article into and withdrawing it from the bath of step (a) to form a metallic coating on the article;
