Available in various finenesses, suitable for sanding metal surfaces, putties, and coatings.
Dry sanding paper is generally made of special Kraft paper and latex paper, using natural and synthetic resins as binders, and is manufactured through advanced high-static sand-planting technology. This product has high grinding power and is not easy to stick to chips. It is suitable for dry grinding. Widely used in furniture, decoration, and other industries, especially coarse grinding.
Advantages: cheap and durable, can be used directly, high power, remarkable polishing effect.
Disadvantages: When grinding, the dust is relatively large, the loss is profound, and it cannot be reused.
In addition to the common paper-based carrier, there are two special forms:
(1) Emery cloth
After changing the carrier from the original thin and brittle paper to cloth, the service life is significantly increased a lot. Because the carrier is thicker, it is also more durable.
(2) Flocking sandpaper
On the basis of the original carrier, a layer of fine fluff is added, which is often used together with the machine
