炭化ケイ素サンドペーパー

Silicon carbide sandpaper is ideal for many different tasks, from smoothing surfaces and removing old paint or primer, to working well on metals and unfinished wood surfaces.

Mercer’s waterproof, resin-bonded sandpaper sheets feature exceptional grain adhesion for wet or dry sanding using a lubricant, making these 9″ by 11″ sheets heat-resistant and suitable for use on curved surfaces.

It is the hardest abrasive

Silicon is among the hardest commonly-used abrasives, second only to diamond, cubic boron nitride and tungsten carbide in terms of hardness. Its hardness makes it useful for polishing rough surfaces as well as wet sanding applications. Silicon carbide sandpaper boasts razor-sharp grains which make light work of sanding glass, stone, plastic medium-density fiberboard metal as well as finishing coats on wood – it is even used surface preparation on automobile restoration projects! This type of paper is often employed during automobile restoration projects!

Silicone carbide sandpaper may have sharp edges and hard surfaces, yet is less durable than aluminum oxide versions due to being more brittle and having narrower grains that wear down quicker. Furthermore, silicone carbide costs more than its aluminum oxide counterpart and should always be stored flat to prevent warping and maintain consistent performance; extreme temperatures should also be avoided for storage as this can hasten its deterioration.

DIY artisans depend on silicon carbide sandpaper as a reliable ally when renovating wooden furniture or priming surfaces for paint, among other tasks. Thanks to its versatility, it can handle everything from shaping and leveling surfaces with coarse grits to creating a flawless canvas for staining or painting using finer grits. Furthermore, its use has proven essential when performing automotive bodywork restoration jobs with flawless finishes being an indispensable tool of the trade.

It is more brittle than aluminum oxide

Silicon carbide sandpaper may be more fragile than brown aluminum oxide abrasive paper, yet still makes for a tough and long-term abrasive option. Ideal for blasting glass, stone, marble and fiberglass surfaces as well as etches well to prepare surfaces prior to finishing, it has also proven useful in automotive sanding as well as wood furniture finishing applications.

Compared to other coated sandpaper options, this abrasive is much quicker and more aggressive in its action, quickly removing material quickly – an excellent option when time is an essential factor in the task at hand. Unfortunately, however, its durability cannot match that of fused alumina as it tends to fracture more readily under high pressure exposure.

This abrasive is ideal for removing rust from metal and old paint from wood surfaces, but should not be used on bare surfaces as its mineral makeup produces tiny new edges that create an uneven scratch pattern. Therefore, for optimal use this should be combined with other types of sandpaper abrasives such as micromesh.

People typically begin their sanding projects using aluminum oxide before switching to silicon carbide to complete them. You can find friable (green) and black silicon carbide abrasives; with latter generally performing better on non-ferrous metals and ceramics. Both kinds come with cloth and paper backings so they can be used with water-based lubricant solutions.

It is used in conjunction with aluminum oxide

Silicon carbide abrasive has needle-like grains that make it extremely hard, cutting glass, plastic and metal with minimal pressure. Unfortunately, it wears down rapidly; hence why aluminum oxide (softer and longer lasting abrasives) are often combined with it as they make an effective combination. Silicon carbide can also be used for blasting blasting gemstone tumbling and polishing various materials.

Silicon carbide not only excels as an abrasive material, but its heat resistance allows it to remain effective for extended sanding applications like automotive repair or woodwork that generate a great deal of heat. Silicon carbide’s exceptional heat resistance also prevents thermal degradation during intense sanding tasks and allows its effectiveness to last much longer periods.

Silicon carbide may be less durable and brittle than aluminum oxide, but it remains an excellent choice for abrading hard non-metals such as ceramics and glass, removing rust from metal surfaces, refinishing wood surfaces and etching aluminum. Furthermore, its brittleness makes it better suited for wet sanding than regular black aluminum oxide which can clog easily.

If you’re working with soft metals like aluminum, use an aluminum oxide abrasive initially before switching over to silicon carbide for the final stages. This will enable you to achieve a flawless surface without wearing out your sandpaper too quickly.

It is more friable than ordinary (black) silicon carbide

Silicon carbide is a hard, sharp mineral used for sanding and polishing surfaces. More durable than aluminum oxide and suitable for non-metallic materials such as plastics, it offers high heat resistance that prevents thermal degradation during sanding; making it the perfect choice for applications requiring high-quality finishes such as metalwork or woodwork applications.

Aluminium oxide is also an ideal material for rough sanding and polishing due to its brittle nature and narrow particle size, meaning it wears down slower. Wet sanding with it can also be done, which makes it great for working on rough surfaces such as removing rust, refinishing wood floors, deburring metal parts, and cleaning glass edges.

Hermes waterproof silicon carbide resin bonded sandpaper is an efficient and effective choice for all of your sanding needs. Featuring reduced friction levels that increase power tool speed and deliver improved results. Perfect for car body work as an abrasive abrasive or finer grades can even prepare paintwork between coats of varnish or paint application, Hermes offers coarse to very fine grit options to meet the specific requirements of every project – and features a hook and loop center design with knockout center which can be removed/pushed back in for improved flexibility!
