| Résumé : |
Alloy wheels with coatings are often stripped using concentrated sulphuric acid. However, the aggressive liquid can penetrate into the microstructure of the metal and have a negative impact on the quality of the subsequent coating. By contrast, a gentle coating removal process causes much less damage to the substrate. |
| Note de contenu : |
- Short stripping times accompanied by material damage
- No damage to the surface of the metal
- Additives compensate for fluid losses
- Acid-activated formulations for even stripping effect
- Fig. 1 : Parts of rims after stripping : Gentle alkaline paint stripper at 120°C, sulphuric acid at 80°C ; gentle acidic paint stripper at 80°C
- Fig. 2 : The surface of the alloy after the removal of the coating in a gentle alkaline paint stripper at 120°C
- Fig. 3 : After the removal of the coating in sulphuric acid at 80°C, the surface of the alloy is covered with silicon particles. Different enlargements are shown |
