Sodium Bicarbonate 40 mesh

Understanding 40 Mesh Soda Blast Media

The "40 mesh" designation indicates a controlled particle size distribution, optimized for a balance of cleaning speed and surface finish. This grade is fine enough to produce a uniform, satin-like profile on soft metals, yet aggressive enough to strip coatings efficiently when used with the correct blast pressure. Unlike harder, angular abrasives like aluminum oxide, sodium bicarbonate is a single-pass media that shatters on impact, providing a gentle scrubbing action that eliminates the risk of embedding or substrate warping.

Key Advantages in Surface Preparation

Selecting the right abrasive is critical for operational efficiency and part integrity. Sodium Bicarbonate 40 mesh offers distinct operational benefits:

• Non-Destructive Cleaning: Safely strips coatings from fragile assemblies, including engines, transmissions, and hydraulic components, without masking or disassembly.
• Water-Soluble Residue: Post-blast cleanup is simplified as the spent media and dust can be dissolved and rinsed away with water, preventing the gritty residue common with other abrasives.
• Environmental Profile: It is non-toxic, non-hazardous, and often permitted for use in environmentally sensitive areas where chemical strippers or silica sand are prohibited.
• Versatile Application: Effective in both dry and wet (dustless) blasting systems, providing flexibility for field and shop work.

Selection and Handling Guidance

To achieve optimal results, we recommend starting with a blast pressure between 40 and 80 PSI, adjusting based on the coating and substrate. The media should be kept dry and free from moisture to ensure consistent flow through the blast pot metering valve. For large-scale industrial stripping, a pressure pot system is ideal, while a siphon system can be used for smaller, detailed work. Always conduct a small test patch to confirm the surface finish meets your specification before proceeding with the full project.
