Cer (Ceramic) abrasives have the longest life and the fastest cutting rate of all abrasives. They ensure an aggressive and consistent cut under moderate to high pressure, as they break down into micro particles, keeping the abrasion surface permanently sharp.

JJ and J cloths are light and flexible fabrics used when surface finishing and uniformity are more important than material removal. They are ideal for finishes where flexibility and conformity are essential, such as contour work, especially on curved surfaces. JJ and J cloths are usually made of cotton, but they are also available in a blend (polyester/cotton) when you want to give them more mechanical strength.

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

Disc holes is an important and often neglected topic. The best solution depends on several factors, namely: the disc diameter, the suction system and the holes in the disc pad. Therefore, there is a huge variety of standard solutions.

The backing of the abrasive in fabric (Vel) is the most common application 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 with a double-sided film on the back of the abrasive (SK) is intended for specific applications that are very demanding in terms of adhesion or support. Adhesion and thermal resistance are important variables and OTA has several alternatives available. It is typically used in rolls, discs and sheets.
There are also Ad (self-adhesive) fixing.
