Pre-coating surface treatment is the underpinning for any high-caliber coating system. Industrial, automotive, and construction uses included, sand blasting is an extremely important step for ensuring surfaces have been optimally prepared to effectively bond with the coating. From Itaichu, you can count on us to furnish top-notch abrasives and surface treatment products like stainless steel shot and other kinds of blasting medias suited to various requirements.
1. Obtaining Clean and Reactive Surface
Eliminates Contaminants Entirely
Prior to applying any coating, the surface should be clean and free of contaminants including rust, mill scale, oil, paint residues, and oxidation. Sand blasting applies high-pressure abrasive blasting to remove all the unwanted material and leave a clean and bare surface. This is necessary to avoid coating failure due to poor adhesion.
Surface Profiling for Improved Adhesion
Coating systems—powder, epoxy, or polyurethane—need a certain surface texture to stick. Sand blasting creates microscopic anchor patterns on the surface, giving it greater mechanical grip. This enhances the durability and lifespan of the coating, particularly under tough environmental conditions.
2. Choosing the Proper Abrasive: Why Stainless Steel Shot Is the Best
Best suited for Reusability and Clean Finishes
Among the various abrasives used at Itaichu, stainless steel shot is especially suitable for producing shiny, bright, and contamination-free surfaces. It’s non-corrosive in nature and gives very little dust, so it can be used in industries where cleanliness and metal integrity are extremely important, including aerospace, automobile, and medical equipment production.
Cost-Effective and Eco-Friendly
Stainless steel shot can be recycled hundreds of times, saving overall consumption and reducing waste. This makes it an economical option for businesses looking to achieve sustainability without sacrificing surface preparation quality. We provide a variety of shot sizes at Itaichu to suit various blasting needs, striking the perfect balance between finish and efficiency.
Conclusion
In any coating operation, the initial step is always the most important. Without adequate surface preparation, even the most sophisticated coatings can fail prematurely. Sand blasting, particularly when used with the proper abrasive such as stainless steel shot, provides a clean, textured, and best-prepared surface for coating applications.
