There is a wide variety of coatings that can be applied to the back of timing belts, and based on your specific application needs, we can recommend the most suitable solution, balancing both technical performance and cost-effectiveness.

Coated belts are used across a broad range of industries, including packaging, glass, wood, ceramics, automation, and foodstuffs. Depending on the product being transported, coatings with varying hardnesses and properties are selected to ensure the optimal level of grip is achieved.

Cold-Glued Coatings

The cold-glued coatings category offers the broadest range of solutions, enabling us to meet the specific needs of each conveyor system effectively. With our expertise, we can ensure the reliable attachment of any type of coating, regardless of the grip requirements or varying hardness levels. This includes materials such as Linatex, Linatrile, food-grade rubber, oil-resistant rubber, and more.

Hot Vulcanised Coatings

This type of coating is applied through the vulcanization of synthetic rubber onto the back of the belt in an autoclave, using either natural rubber or polyurethane. The available rubbers range in hardness from 45 Shore to 80 Shore and can be produced in various colors (e.g., Tenax, para rubber, etc.).

The advantage of this vulcanized coating over cold-applied coatings is the superior adhesion achieved through the high temperature process, coupled with an excellent price-to-performance ratio.

Silicone and Silicone Rubber Coatings

Silicone rubber coatings, available in various hardness levels (ranging from 30 to 65 Shore), are primarily used for transporting films, pipes, and cables. These coatings are moulded onto sleeve belts with a length of less than 1000 mm.

The silicone coating with a hardness of around 30 Shore is applied through a hot pour process, followed by grinding. It is FDA certified and can also be applied to longer belts when necessary.

Extruded Coatings on Timing Belts

On the back of timing belts supplied by the meter (hardness 92 Shore), an additional layer can be extruded. This layer can be made from a softer polyurethane (70/85 Shore) or, alternatively, a mixture of rubber and polyurethane (50/60 Shore) to enhance the grip.

Foam Coatings and Dual Coatings

We offer a wide range of foam coatings designed to transport objects with unusual shapes or fragile products (such as Sylomer, neoprene foam, foam rubber, etc.). Unlike denser coatings, foams do not provide a high level of grip. However, in such cases, a dual coating approach can be applied—combining foam with a denser material. This allows the foam’s deformability to be paired with the strength and grip of more solid materials like silicone, Linatex, and others.

1 – Linatex natural rubber coating, hardness 38 shore, excellent grip

2 – The 30 shore silicone coating offers a high level of deformability

3 – White food-grade rubber coating (FDA approved), hardness 60 shore

4 – Neoprene foam coating, excellent deformability and good wear resistance

5 – Polyurethane and rubber compound extruded onto the back of the timing belt, hardness 55 shore

6 – Silicone rubber coatings available in 30, 40, 50 and 65 shore hardnesses

7 – The back of the timing belt can be coated with low-friction and wear-resistant material

8 – We can quickly create new moulds for specific customer developments

9 – The coating in linatrile rubber, hardness 55 shore, has a good grip and excellent resistance to wear

10 – The coating in vulkolann has a hardness of 70 shore and excellent wear resistance

11 – Sylomer foam coatings are different colours depending on their density

12 – AT10 timing belt with medium-porosity foam rubber coating

13 – Blue Sylomer coating with back in hot-poured silicone which is then ground

14 – Dual coating composed of blue Sylomer and cold-glued linatex rubber

15 – A honeycomb geometry for the back is recommended in dusty environments (ceramics)

16 – It is possible to have pre-extruded coatings on belts with different types of geometries
