Description

The sealing process consists in treating chromate coatings to D.T.D. 9 11 on magnesium-rich alloy components with a solution of a stoving resin by dipping. draining and baking. In certain circumstances spraying may replace dipping. Three successive applications of the resin are made with the component held each time in a different attitude to facilitate even coating. When it can be demonstrated (see para. 6b) that two coats applied at the standard viscosity by dipping give a film of thickness at least 0.001 inch, two coat sealing may be permitted at the discretion of the inspector.
