Explanation on Acid-base Corrosion of Profile Surface Coating

Impact of Acid-base Liquids on Powder-sprayed Surface:

When coming into contact with acidic or alkaline substances, the powder coating may have chemical reactions, causing corrosion or discoloration on the surface. To ensure the long-term durability and aesthetics of the powder-sprayed surface and avoid acid-base contact: During the using process, make sure to prevent the sprayed surface from direct contact with acid-base liquids. In case of accidental contact, rinse it immediately with clean water.

When in touch with acidic or alkaline substances, the powder coating may have chemical reactions, leading to corrosion or discoloration on the surface;

Avoid using corrosive liquids such as caustic soda, strong detergents and toilet cleaners during the decoration and cleaning process.

The impact of acid-base liquids on the powder-sprayed surface is remarkable. When the powder coating contacts acidic or alkaline substances, these highly corrosive liquids may react chemically with the coating materials. Such chemical reactions usually result in corrosion on the coating surface.

Acid-base liquids may also lead to changes in the coating color. The originally uniform appearance may become mottled and uneven, affecting the aesthetics. Therefore, when using powder-sprayed materials, special attention should be paid to avoiding contact with acid-base liquids to guarantee the long-term durability and aesthetics of the coating.

During decoration, the protection of windows is often neglected, leaving a lot of scratches and stains on the window surfaces after the decoration is finished. This not only affects the aesthetics but also shortens the service life of the windows.

The following are cases of how to protect windows after installation:
