Application of garnet
Coarse 20/40mesh 30/40 mesh : Used for general purpose repair and maintenance blasting including removal of weathered paint, rust, mill scale, and other coatings from surfaces of stainless steel, carbon steel, aluminum parts and etc.
Medium 30/60mesh : Utilized for new steel, light paint and rust removal and special maintenance applications requiring reduced profiles.
Fine 60mesh 80mesh : Applicable for light blasting requiring a clean surface and minimum anchor profile including brush-off blast or high-pressure water blast system.
Fine 120mesh 150mesh 200mesh 300mesh: available for special application based on customer’s request.
