Presentation of our individual painting options
29.01.2025
At the customer's request, we can provide additional protection for both our customised drive pulleys and fully machined components through passivation, priming and painting. In our in-house paint room, the drive elements are painted manually, taking into account their area of application. Find out more about our range of services and reference projects.
We offer customised solutions for the surface treatment of our drive pulleys to ensure optimum corrosion protection, improved durability and a high-quality surface finish.
Passivation
Cast drive discs are often exposed to high loads and environmental influences in industrial applications. Targeted passivation protects the surface from corrosion and extends the service life of the components. Special chemical treatments form a protective layer that prevents oxidation of the material and at the same time improves the adhesion of subsequent coatings such as primers or paints. This maintains the functionality and reliability of the drive discs in the long term.

Priming
Priming with a 1K or 2K paint system is standard. It serves as a protective layer and adhesion promoter for the final coating. Parameters such as the wet bulb temperature, the dew point and the temperature are recorded in a coating protocol on request and can be documented in a qualified certificate.
| 1K coating system (one-component system) | 2K coating system (two-component system) | |
|---|---|---|
| Properties | Consists of a single component and cures by evaporation of the solvent or by physical drying (air drying). | Consists of a base component (lacquer) and a hardener, which are mixed before application. Curing takes place through a chemical reaction. |
| Advantages | Easy to use as no mixing is required | High resistance to mechanical stress, chemicals and weathering |
| Quick drying | Longer durability and better corrosion protection properties | |
| Good adhesion and protection for less stressed components | High adhesion even on difficult substrates | |
| Disadvantages | Lower chemical and mechanical resistance than 2K systems | More complex processing due to exact mixing ratios |
| Less resistant to solvents and high loads | Limited processing time after mixing (pot life) | |
| Higher material and cost expenditure | ||
| Areas of application | Less stressed components or when the focus is on simple processing | Highly stressed surfaces that are exposed to high mechanical, chemical or weathering influences |
Painting
We offer professional painting to protect customised cast drive pulleys. Whether corrosion protection, increased resistance or individual colour coding - we supply custom-fit coating solutions. Choose the optimum coating for your requirements and benefit from long-lasting quality and perfect surface protection.
Corrosion protection
Cast iron can rust on contact with moisture. Painting protects the surface from oxidation and extends the service life of the disc.
Wear protection
Painting can protect the surface against abrasion and external influences, especially in environments with dust, chemicals or high humidity.
Optical reasons
Painting ensures a uniform and professional appearance (CI colouring), which can be particularly important for visible components. All RAL colours are possible.
Labelling and differentiation
Different paint finishes or colour codes can be used to identify certain specifications or manufacturers.
Improved cleanability
Painted surfaces are often smoother and less porous than untreated cast iron, which makes cleaning easier and reduces the adhesion of dirt.
After drying, the coating thickness is checked and an adhesion test can be carried out, e.g. by cross-cut testing in accordance with DIN EN ISO 2409.
Standardised commercial goods from the Far East are usually supplied with a phosphated surface. We can also offer this process for our customised products on request. It is also possible to galvanise or nickel-plate the drive pulleys. We co-operate with local specialist companies for this purpose.
Whether standardised protective coatings or special colour coding - we adapt the coating exactly to your requirements. Contact us and let us develop the optimum solution for your drive pulleys together!
