Abrasives

Kurval offers a wide range of abrasives for both rotary and linear sanding. The sanding process uses abrasive grain embedded in the backing. The grain size is therefore a direct cause of the sanding scratch. We therefore recommend not starting too coarsely to avoid additional work to undo an incorrect initial step. This step, and estimating the correct grain size, is often difficult. The materials to be sanded determine the choice of abrasive grain. Stainless materials often require a different grain than ferrous materials such as iron, steel, and cast iron. For stainless steel, we therefore recommend using silicon carbide or zirconium (an industrial diamond grain).

Abrasives can also be effectively applied in rotary applications, such as in flap discs or sanding hoods. The combination of sandpaper with a sanding fleece allows for a better finish than sanding alone. This is a good solution for surfaces where visibility is a factor.

Sandpaper – whether waterproof or not – varies significantly in quality. This is due to the combination of a good grit and proper bonding to the paper backing. If the grit is stressed and breaks, it can build up and leave deep scratches, immediately distorting the image. Therefore, a higher-quality sandpaper is always worthwhile.

Our sanding program is so extensive that we can't describe it in a few sentences. So please feel free to ask about the possibilities.
