Olivine Sand 40 mesh

Low-Silica Blasting Media for Safer Surface Preparation

Olivine sand is a magnesium iron silicate mineral prized in the abrasive blasting industry for its combination of high specific gravity, moderate hardness, and angular particle shape. The 40-mesh particle size distribution is a workhorse grade, balancing cutting speed with profile control. It is widely used for removing mill scale, rust, and old coatings from structural steel, tanks, and pipelines before repainting or coating.

Unlike silica sand, olivine contains less than 1% free silica, drastically reducing the risk of silicosis. This makes it a compliant choice for projects governed by strict health, safety, and environmental (HSE) regulations. Its high density ensures efficient energy transfer upon impact, leading to faster cleaning rates and lower media consumption compared to lighter mineral slags.

Performance and Application Profile

The angular morphology of olivine sand creates a sharp, clean surface profile essential for mechanical bonding of paints, epoxies, and thermal spray coatings. The 40-mesh grade is particularly effective for:

• Structural Steel Blasting: Achieving a SA 2.5 (Near White Metal) or SA 3 (White Metal) cleanliness standard with a consistent 50–75 micron anchor profile.
• Concrete Surface Preparation: Removing laitance and opening surface pores for coating or overlay adhesion.
• Marine and Offshore Maintenance: A preferred media in shipyards and offshore platforms where silica sand is banned.
• Industrial Tank and Pipeline Coating: Preparing surfaces for high-performance linings.
