Heavy Equipment & Off-Road

Surface treatment put to test: A multitude of standards, diverse base materials and extreme conditions in everyday life. The requirements of the heavy equipment and off-road industry are very demanding. Our eco-friendly and efficient technologies ensure an excellent and long-term surface quality.

Off-road vehicles, construction equipment, industrial machines and agricultural vehicles are subject to high expectations: they must be robust and sometimes tough conditions and yet the same time remain functional over a long period of time. Quality and design have been for many years and are becoming even more so important purchasing criteria. With our system solutions, you are driving on the safe side concerning corrosion protection and excellent paint adhesion.

Agricultural, construction and earthmoving (ACE) machines have to withstand tough conditions. Corrosion protection layers have to demonstrate what they are capable of. Alongside a high-quality surface finish, the cost-effectiveness and flexibility of the pretreatment technologies are playing an increasingly important role. The new systems Gardo® Plus and Oxsilan® that can be used with a variety of metals and meet the demanding market requirements.
In agriculture, corrosion protection layers have to demonstrate what they are capable of. When harvesters plough through densely grown wheat fields or tractors till the fields in every wind and weather, stone chipping, wet conditions and sludge are aggressively acting on the vehicle bodies and add-on parts. Nonetheless, the paints applied must exhibit highest brilliance and color fidelity. Under such demanding conditions the high flexibility and economic efficiency of the heavy metal-free Oxsilan® technology play an ever greater role. This is why this technology is meanwhile increasingly applied by nearly all renowned agricultural machinery manufacturers.
For decades, yellow and green chromating have been the technologies of choice for the corrosion protection of metals. Rising costs for health, safety and environment as well as changed market demands have resulted in a situation where chromium-free alternatives are increasingly gaining a foothold in the market. A comparison of old vs. new technologies shows why: the eco-friendly technologies show better results in key aspects.
