Sandblast - Sandblast Media

At Olimag Sands, we offer high quality resistant sands that offer optimal results which are perfect for Sandblast Media.

Sandblasting, also known as abrasive blasting, is a process used to clean, prepare, or finish surfaces by forcibly propelling abrasive material against the surface under high pressure. The type of abrasive used and the blasting parameters significantly influence the resulting surface profile. Here are different types of surface profiles that can be achieved by sandblasting metal surfaces with specific abrasives:

  1. Smooth Profile: JETMAG 100 (60B2) (Surface or anchor pattern profile of 0.5 to 1 mils)

    • Abrasive: Fine abrasives such as glass beads or aluminum oxide.
    • Purpose: Achieve a smooth surface finish with minimal roughness. Ideal for applications where aesthetics or coating adhesion is critical.
  2. Medium Profile: JETMAG 35-70 (Surface or anchor pattern profile of 1.5 to 2.5 mils)

    • Abrasive: Common abrasives like silica sand or garnet.
    • Purpose: Create a moderate level of roughness on the surface. This profile is often suitable for preparing surfaces for coatings or adhesives.
  3. Coarse Profile: JETMAG 32B4 (Surface or anchor pattern profile of 2 to 3 mils)

    • Abrasive: Heavy abrasives like steel shot or grit.
    • Purpose: Generate a more substantial texture on the surface. This profile is beneficial for enhancing adhesion in applications where a thicker coating is required.
  4. Angular Profile: JETMAG 30-60 (Surface or anchor pattern profile of 2.5 to 4 mils)

    • Abrasive: Abrasives with angular shapes, such as steel grit.
    • Purpose: Produce a surface with sharp peaks and valleys. This profile is useful for applications requiring strong adhesion, such as coatings on structural steel.
  5. Deep Profile: JETMAG 16-60 (Surface or anchor pattern profile of 4 to 6 mils)

    • Abrasive: Aggressive abrasives like crushed glass or aluminum oxide.
    • Purpose: Create a deep and coarse surface profile. Ideal for heavy-duty applications where maximum adhesion is essential, such as preparing surfaces for epoxy coatings.

The selection of the abrasive type, size, and blasting parameters (pressure, distance, angle) plays a crucial role in determining the final surface profile. It's essential to match the abrasive and blasting conditions to the specific needs of the project, considering factors such as material type, coating requirements, and environmental considerations. The right surface profile ensures optimal adhesion and performance of subsequent coatings or treatments applied to the metal surface.
