Silicon Carbide Sandpaper (Kraft / Latex Paper)

Product Overview

Silicon carbide sandpaper is a high-performance coated abrasive made with silicon carbide grains, kraft or latex paper backing and a resin bond using high-voltage electrostatic grain coating. Dry and wet / dry types are available for sanding and polishing metals, wood, furniture, automotive parts, plastics, ceramics and glass. Formats include sheets, rolls and discs, with a complete P60-P3000 grit range.

Technical Specifications

Product Types

Silicon carbide sandpaper is divided into two main types by backing material and operating method:

1. Kraft Paper Sandpaper

High-strength kraft paper provides a flexible, tear-resistant and economical backing. Dry and waterproof types are available:

Dry type: a synthetic resin adhesive suits dry sanding in furniture and interior finishing, with easy swarf release.

Waterproof type: special water-resistant treatment enables wet sanding for automotive and hardware applications.

2. Latex Paper Sandpaper

Latex paper provides a soft, flexible, water- and oil-resistant backing for curved surfaces and fine polishing. Available latex contents are 15% and 30%; higher latex content improves water resistance and flexibility.

Key Features

1. Hard, sharp-cutting silicon carbide abrasive

Silicon carbide has high hardness (Mohs 9.0-9.4) and sharp, friable grains for efficient grinding. Service life can be more than 30% longer than conventional sandpaper.

2. Anti-loading and antistatic treatment

A special antistatic surface coating reduces swarf loading and adhesion during sanding, extending paper life and improving grinding efficiency.

3. Flexible paper backing for complex profiles

Kraft and latex paper backings combine flexibility and toughness for manual sanding and clamping in pneumatic or electric sanding equipment, following curved and contoured surfaces.

4. Flexible wet and dry applications

Waterproof products can be used with water to lower grinding-zone temperature, prevent heat discoloration and eliminate airborne sanding dust during wet operation.

5. A full grit range in multiple formats

Grits from P60 to P3000 can be supplied as sheets, rolls, hook-and-loop discs and self-adhesive discs for different equipment and methods.

Available Grit Sizes

Silicon carbide sandpaper offers a complete grit range from coarse grinding to ultra-fine polishing:

Grit selection: P60-P120 for coarse grinding, P150-P240 for intermediate grinding, P280-P600 for fine grinding, and P800 or finer for ultra-fine polishing.

Typical Applications

Furniture: rough sanding bare wood, leveling primer and polishing topcoats

Automotive refinishing: sheet-metal sanding, paint finishing and wheel hub polishing

Metalworking: deburring, rust removal and mirror polishing of stainless steel, aluminum alloys and hardware

Electronics and plastics: sanding and polishing electronic housings and plastic parts

Construction and decoration: sanding wall filler to improve uniform coating adhesion

Packaging

Sheets: 100 sheets per pack, standard 230×280 mm, wrapped in kraft paper

Rolls: widths of 100-1650 mm and lengths of 50 or 100 m; can be slit to order

Discs: boxed by piece count, with hook-and-loop or adhesive backing

Custom packaging: special packaging and branding on request

Storage Recommendations

To maintain product quality during storage, observe the following conditions:

Store in a cool, dry, ventilated warehouse away from direct sunlight. Relative humidity should preferably be ≤60% to prevent moisture-induced deformation and adhesive aging.

Store sheets flat without heavy pressure to avoid creasing or deformation. Hang rolls or store them upright to prevent moisture-induced curling.

Separate and clearly label different grit sizes to prevent mixing. Avoid contact with acids, alkalis, organic solvents and other chemicals.
