Chromium free Passivation Additive

LW-19 Chromium free Passivation Additive is a remarkable product in the field of metal surface treatment. As a passivation agent, it stands out for its unique properties and environmental friendliness. It is a colorless transparent and eco-friendly additive, also known as a Silane ceramic film forming agent or anti-corrosion additive.

In the context of aluminum surface treatment, LW-19 serves as a Powder Coating Agent. It utilizes composite salts to create a uniform chemical conversion film on the aluminum surface. This not only effectively enhances the adhesion of the coating film but also significantly boosts the corrosion resistance of both the surface and the coating. It is completely chromium-free, fully complying with green environmental protection requirements, and can perfectly substitute traditional chromium passivation coatings for aluminum.

When it comes to the Aluminium Anodizing Process, LW-19 can play an important supplementary role. Although it is mainly a passivation agent, its ability to improve the surface condition of aluminum can contribute to better results in the anodizing process. After the anodizing, for Cleaning Anodized Aluminum, LW-19 can also have a positive impact as it helps maintain the integrity and quality of the surface, making the cleaning process potentially easier and more effective.

As an aluminum cleaner, LW-19 is not a traditional cleaner in the sense of removing dirt and grime, but its function of forming a conversion film can indirectly contribute to keeping the aluminum surface in a better state. It helps prevent the accumulation of substances that could lead to dirt or corrosion, thus having a certain cleaning effect in the long run.

Moreover, in some cases where enhancing the appearance of aluminum is desired, LW-19 can act as a kind of aluminum brightener. Since it forms a transparent and uniform film on the aluminum surface, it can give the aluminum a more refined and bright appearance.

Although it is not primarily an Anodizing Agent, its compatibility with the anodizing process and its benefits for the aluminum surface make it a valuable addition in the overall treatment of aluminum. The features of LW-19, such as being environmentally friendly (chromium-free, without heavy metals, non-toxic, and having no health hazards), simple to use (requiring control of the bath solution pH value between 2.8-3.8), energy-saving (operating at room temperature and using running water for bath make-up), and having stable bath solution and a colorless (transparent) coating film, make it a highly practical and reliable choice for various aluminum surface treatment applications related to anodizing, cleaning, and passivation.
