SiC (Silicon Carbide) is the hardest and sharpest of the minerals used in abrasives. Its hardness and very sharp form, make this abrasive ideal for various applications that do not require great pressure when cutting. Its grains are friable and, when broken, they continually expose new cutting edges that allow rapid removal of the material. It is more aggressive than Alox but wears out more quickly.

Lightweight and flexible, A or B papers are mainly used for manual operations or to support delicate, fine-grained operations. They can be prepared for wet work.

The grits presented are the most common for the operations in question, but they do not exhaust all available alternatives. We will be happy to help you find the best solution for your case.

The diameters indicated are the most common in the industry. OTA has many more dimensions available, as it produces formats tailored to the needs of its customers.

The backing of the abrasive in fabric (Vel) is the most common situation in Europe and is designed to allow the use of discs or sheets on equipment or plates with a Velcro® type system to allow easy, quick and reusable fastening. The type of fabric is always adjusted to the abrasive in question and comes in a wide range of weights and strengths.
The self-adhesive solution (Ad) on the back of the abrasive, typically of the PSA type, allows use similar to Vel, and is intended for specific applications, such as high precision. Adhesion is an important variable and OTA has several options available. It is typically used on discs and sheets.
