Description
Product Description of the Mirka Sica Coarse / Sica Closed Antistatic Paper Wide Belts
Sica Coarse - Grits 40-60Sica Coarse is ideal for coarse sanding and calibration sanding of wood and MDF. It features silicon carbide grains, in combination with an open coating, to provide long lasting performance on tough sanding applications. In addition, the product’s anti-static characteristics minimise dust load and help prevent clogging.
Recommended for hard wood & MDF, as well as plastics & composites due to the silicon carbide grains requiring less pressure and providing a finer scratch pattern without gouging the workpiece.
Technical Specifications
• Grain: Silicon carbide
• Color: Black
• Backing: Antistatic T-paper
• Bonding: Resin over resin
• Grit range: P40-P60
• Coating: Open
Sica Closed - Grits 80-220
Designed for belt sanding and sanding of MDF and other materials containing mineral debris, Sica Closed is a fully antistatic product that’s suitable for materials covered with water-based surface treatment coatings. It maintains its shape well and the silicon carbide grains produce less fibre rising and a finer scratch pattern than products using aluminium oxide grains. The result is a smoother sanded surface and a better final finish after surface treatment.

Why Use Silicon Carbide?
Silicon carbide is the hardest common abrasive grain with exception of diamond. Because it is tougher and sharper than aluminium oxide, even though it tends to wear down more quickly, it is still a long-lasting product that works well for polishing, harder materials, and uneven surfaces. It is the only grain that works well on glass, stone, and marble and is especially useful for metals, especially the tougher kinds, while also suitable for cork and MDF as well.Silicon carbide is widely used in wet sanding applications, including automotive polishing and the polishing of stone and marble. This works well in coarser grits for deburring metal and glass, rust removal, and refinishing wood floors (cutting through/removing earlier finishes). It is standard practice to use aluminium oxide for rough sanding raw wood and move to silicon carbide for finishing phases of the same job since it may also be used to sand in between finishing coatings in woodworking projects.
As an abrasive it is a somewhat adaptable and forgiving material that may be used in power and manual sanding applications, in the form of, among others, belts, discs, sheets, and sponges.
