Abstract
Metal treating compositions, containing hexavalent-chromium-providing substance and pulverulent zinc, and which find particular utility in the coating of metal substrates prior to painting, now exhibit extended bath stability through pH control. The key to the control is achieved during preparation of precursor components. Such components of controlled, or adjusted, pH are then blended together to form a bath of excellent stability e.g., extended freedom from gelation.
