The paint removal process in metal surface treatment is the process of removing old coatings, paint films, or other coatings from the metal surface. Paint removal is typically carried out through chemical treatment to prepare the surface for subsequent painting, welding, or other surface treatment processes. Chemical paint removers are commonly used, working by dissolving or softening the coating, making it easier to peel off from the metal surface.
The paint removal process of paint remover
Surface Cleaning
Before using paint stripper, you first need to clean the metal surface to remove oil, dust or other impurities. Cleaning can be done with solvents or detergents, making sure the paint stripper can effectively reach the coating.
Soak or spray paint stripper
Brushing method: Use a brush to apply the paint remover evenly on the metal surface to ensure complete coverage. When applying, avoid missing or uneven application. Immersion method: Completely immerse the metal piece in the paint stripper solution, making sure the coating is completely covered. The soaking time will vary depending on the thickness of the coating and the type of paint stripper used.
Reaction Time
A chemical reaction occurs between the paint stripper and the coating, which can usually be observed in about 10 seconds. The coating softens, expands and breaks down, separating from the metal surface. Complete removal takes 1-3 minutes, depending on the type of coating, its thickness and the nature of the paint stripper.
Clean the surface
After paint stripping is complete, the metal surface must be thoroughly cleaned with water or an appropriate solvent to remove residual paint stripper and flaking coating. After cleaning, make sure the surface is clean and there is no paint stripper residue to avoid affecting subsequent processing or painting.
How to choose industrial paint remover?
When choosing a paint stripper, consider the coating type, metal material and paint stripper ingredients. Different coatings and metals require different paint removers to ensure the paint removal effect without damaging the substrate. According to the coating thickness and metal material, choose a suitable paint remover, and try to choose an environmentally friendly paint remover to protect users and the environment.
