Silicon Carbide Coated Sand Paper is a high-performance industrial dry abrasive paper tailored for hard material polishing and high-precision surface finishing. It adopts premium sharp silicon carbide grains and high-tensile kraft paper backing with heat-resistant resin bonding. Featuring ultra-hard abrasive property, self-sharpening effect and uniform grinding performance, this sandpaper excels at polishing hard surfaces that ordinary aluminum oxide sandpaper cannot handle. It is widely applicable for dry sanding of glass, stone, stainless steel, plastic and high-hardness paint surfaces, with complete grit options for bulk wholesale and customized OEM service.

Aluminum-Oxide Coated Sand Paper

Material & Craft Features

Abrasive Grain: High-purity silicon carbide (SiC) grains, higher hardness and better self-sharpening ability than aluminum oxide. The grains produce new cutting edges during grinding, maintaining lasting sharpness without passivation.

Paper Backing: Heavy-duty high-strength kraft paper base, excellent tensile and tear resistance, stable structure during manual and mechanical dry sanding, not easy to break or deform.

Bonding Technology: High-temperature resistant resin adhesive coating, firm combination of abrasive grains and paper base, effectively prevents grain shedding during high-intensity dry grinding.

Precision Coating Process: Uniform electrostatic grain distribution ensures consistent grinding traces, avoiding uneven surface scratches and improving finishing uniformity.

Widely used for glass, marble, granite and stone processing, stainless steel and alloy hardware polishing, hard plastic, acrylic and resin product finishing, high-hardness paint surface sanding, craft workpiece precision grinding and general industrial hard material surface treatment. Compatible with manual sanding, sanding blocks and orbital sanders.
